Title: Monitoring the Jet and the LMXB population in Centaurus A

PI Name: Stephen Murray

We propose 2x5ks snapshot of the nearby galaxy Centaurus A to monitor the jet and the LMXB population for flaring or any other temporal changes. Dramatic variability has been observed in the M87 jet over the period years. We will monitor the Cen A jet for similar variations on similar timescales. The proximity of Cen A also suggests that we may see temporal changes in the jet morphology during a flare since Cen A is the only jet in which Chandra's resolution probes the radiative loss spatial scale. We will also monitor the LMXB population to search for ULXs and other bright (Lx>5E38 ergs/s) transients. Such transients give important clues about the formation and evolution of the compact binary population in early-type galaxies.

Title: X-raying the circumnuclear matter in the Broad Line Radio Galaxy 3C445

PI Name: Claude Canizares

We propose to observe the radio galaxy 3C445 with HETG for 416 ks. The objectives are: 1) to improve the constraints on the gas density of the soft X-ray emission lines component by measuring the line ratios of the He-like triplets in the HETG band; 2) to confirm or exclude the presence of a high velocity outflow in this source by modeling the 2-8 keV continuum and Fe K band features.

Title: A Large, Economical Snapshot Survey of the Most-Luminous Quasars from the Sloan Digital Sky Survey

PI Name: Gordon Garmire

We propose to obtain Chandra ACIS-S snapshot exposures of 66 of the most optically luminous quasars found in the Sloan Digital Sky Survey Data Release 7 quasar catalog. Observations of these targets will substantially enlarge the sample of the most-luminous SDSS quasars having complete, sensitive X-ray coverage. Our targets represent the rapid growth phases of the most-massive black holes in the Universe, and these observations will provide the best statistical constraints to date upon the X-ray accretion emission from such growing black holes. They will break luminosity-redshift degeneracies in X-ray vs. optical/UV studies, identify remarkable new objects that provide insight into quasar physics, and reveal the best objects for follow-up X-ray spectroscopy.

Title: PKS2155-152: Measuring the mechanical energy of radiatively bright AGN

PI Name: Stephen Murray

This 20 ks observation of PKS2155-152 will be used with the existing 9 ks observation and a deep potential observation to characterize the surrounding hot atmosphere and cavities. PKS2155-152 may be near the end of its radiative "quasar" phase, but currently still near its Eddington luminosity, but surrounded by a hot gas atmosphere. We will determine the mechanical energy of the AGN outburst required to produce the X-ray cavities and compare this with the radiative luminosity.

Title: The Radio--X-ray--BH-Mass Plane for the Smallest Supermassive Black Holes

PI Name: Kayhan Gultekin

The fundamental plane relates the X-ray luminosity, radio luminosity, and mass of accreting BHs and demonstrates an intimate connection between BH inflow and outflow. Existing data are mostly from SMBHs with Mbh > 10^7. It is not clear whether the plane holds below this. Small SMBHs are critical to our understanding of BH formation and growth as well as feedback in the early Universe. We propose to survey all known BHs with mass estimates Mbh < 10^6.2 that have no CXO or XMM observations, but have VLA FIRST radio detections. With modest CXO exposures and new EVLA observations of these 7 sources plus 4 archival sources, we can test the robustness of the plan at low-mass and whether accretion properties scale from stellar BHs thus testing how BH feedback scales with mass and accretion rate.

Title: Kinematics of the outflow in Mrk 509: Completing the puzzle

PI Name: Jelle Kaastra

We propose to observe the Seyfert 1 galaxy Mrk 509 with Chandra HETGS for 280 ks in order to accurately determine the kinematics of the ionized outflow and investigate the properties of the most highly ionized gas. This observation will allow us to study the -800km/s component of the outflow. Combining this with the current information on the location, ionization structure and kinematics of the other components, for the first time we will be able to obtain a two-dimensional picture of the outflow. In addition accurate column densities of Mg XI, Mg XII, Si XIII and Si XIV will allow us to obtain relative abundances of these elements.

Title: AN X-RAY MICROLENSING TEST OF THE AU-SCALE CENTRAL STRUCTURE OF THE QUADRUPLE QUASAR 2237+0305

PI Name: Shin Mineshige

We propose Chandra observations of the gravitationally lensed quasar Q2237+0305 during a microlensing event to reveal its AU scale central structure. The quasar being monitored from the ground regularly to ascertain the onset of the event. As it occurs, we will measure X-ray spectral variations with Chandra and compare with those taken before and after the event. Since a small region of the quasar accretion disk is strongly magnified during the event, we will be able to limit the mass contained on scales of several AUs and to probe the physical properties of X-ray emitting gas in the vicinity of the black hole. Together with ground-based telescope, we can resolve the quasar emission regions at multiple wavelength. This provides a critical test of quasar accretion disk theories.

Title: AGN triggering caught in the act: a triplet of nuclei in the merging system NGC3341

PI Name: Stefano Bianchi

We propose to observe NGC3341 with Chandra ACIS-S for 50ks in order to determine the AGN activity of the three nuclei of this disturbed system. Given the uniqueness of this close (<10 kpc) merging system, any outcome of this experiment will provide exciting results: if all the three nuclei turn out to be active, NGC3341 will become the only known example of a triple AGN system, with important consequences on our knowledge of the formation of SMBHs and large structures; if two nuclei are AGN, this galaxy would host one of the handful of bona-fide dual AGN; finally, if only the offset B nucleus is confirmed to be active, NGC3341 would be the first galaxy to host an AGN not in its center, implying a substantial revision of the current paradigms of AGN triggering.

Title: Extending the Chandra 3C Snapshot Survey: Radio Galaxies with 0.3
PI Name: Francesco Massaro

In the past decade many 3C sources have been observed by Chandra and in particular, during AO9 and AO12, we successfully carried out a Chandra snapshot survey of all unobserved 3CR sources with z<0.3. The results confirm our expectations and this proposal requests an extension to higher redshift: to obtain a 12ks exposure for each of 20 previously unobserved by Chandra, 3C radio galaxies with redshifts between 0.3 and 0.5. This will yield detections of new jets, hotspots, and nuclei; the later relevant to evaluate the AGN unified models. The observations will also provide a versatile, complete, and uniform database that will be a valuable resource for the astronomical community, and since it is designed as a `legacy' program, we waive proprietary rights.

Title: CHANDRA SURVEY OF DUAL ACTIVATION IN HARD X-RAY SELECTED MERGING AGN HOSTS

PI Name: Richard Mushotzky

One of the fundamental questions of AGN is why a given source is active while another in a superficially similar galaxy is not. Our recent survey of nearby hard X-ray selected AGN has found a high rate of mergers (30%) compared to optically selected AGN (2%). At least 18% (10/58) of these systems have multiple X-ray AGN, many of which can only be detected with the resolution of Chandra (e.g. NGC 6240 and Mrk 463 which are in our sample). We propose to observe AGN in mergers with multiple nuclei within 15", which can only be detected with the resolution of Chandra. This data, along with our sample observed last year, will determine the incidence of multiple accreting nuclei in the low redshift Universe for the first time.

Title: ToO Observations of a New TeV Blazar Detected by VERITAS

PI Name: Markus Boettcher

We propose a 40 ksec ACIS-S ToO observation of a new TeV gamma-ray blazar detected in a flaring state at very-high-energy (VHE) gamma-rays by VERITAS. The proposed Chandra observations will be coordinated with ground-based radio, infrared, optical and VHE gamma-ray observations, and combined with simultaneous MeV - GeV gamma-ray data from Fermi. Chandra observations are needed for a detailed spectral and timing analysis, in order to pin down the continuum spectral shape and spectral variability on time scales of a few hours. This is crucial to put stringent constraints on gamma-ray emission models of blazars as well as the intensity, spectrum, and cosmological evolution of the extragalactic background light.

Title: Quasar jet knots: an under-exploited tool for jet physics

PI Name: Diana Worrall

B0800+608 is a superb example of a long quasar jet with well resolved knots that wiggle within a straight envelope. The proposed observation is designed to detect knot X-rays that we will model to probe emission mechanisms and jet mechanical power. Unique among quasar observations, this will explore the exploitation of radio/X-ray lateral knot offsets to test the most commonly adopted model for quasar jets, with its extreme physical implications, and the origin of knots. We will also search for unusual features in an X-ray emitting atmosphere that may be responsible for the dramatic and unusual disruption of the counterjet into a swirl with no observable radio hotspot.

Short (10 ksec) Chandra observations of 3C 270.1 (z=1.532) show faint X-ray emission associated with one or both of the southern hotspots and with a bend in the northern counter-jet. Additional diffuse X-rays are unassociated with any currently observed radio structure. We request deeper X-ray and EVLA observations to explore the origin of the intriguing diffuse emission, which may be associated with a cluster of galaxies around this source, and investigate the relations between the radio structure and the associated X-rays suggested in our preliminary analysis.

XMM-Newton revealed the presence of a prodigious Iron line and diffuse emission around this source. With 100 ks ACIS observations, we will measure the spectrum of the Compton-thick AGN resolved from its host cluster and will model the cluster gas physical parameters, including a first determination of the temperature change with radius. We will also search for X-ray counterparts to complex optical structures related to feedback and interactions within the assembling cluster environment. IRAS F15307+3252 represents a unique opportunity for detailed study of structure growth and feedback in the distant universe.

Title: Exploratory X-ray Monitoring of z>4 Radio-Quiet Quasars

PI Name: Ohad Shemmer

We propose to continue our exploratory X-ray monitoring project of some of the most distant radio-quiet quasars by obtaining one snapshot observation per Cycle for each of four sources at z>4. Combining these observations with three archival X-ray epochs per source will provide basic temporal information over rest-frame timescales of ~2-4 yr. We are supporting this project with Swift monitoring of luminous radio-quiet quasars at z=1.3-2.7 to break the L-z degeneracy. Ultimately, our monitoring project will serve as the benchmark for X-ray variability studies of quasars at the dawn of the modern universe. Our prime goal is to test claims that quasars were more X-ray variable in the early universe with implications for evolution scenarios of the central engine in active galactic nuclei.

NGC 1365 is an obscured Seyfert, well known for its variable X-ray obscuration. The column density varies on timescales of days, placing the X-ray absorber on the scale of the inner BLR. It also exhibits a highly ionized outflow, from a putative disk wind. We propose a 200ks Chandra HETG observation of NGC 1365. The goals are to: (i) obtain the first high resolution spectrum of the highly ionized outflow in NGC 1365, directly resolving the widths of the Fe K absorption lines or (ii) obtain the first grating spectrum in its Compton-thick state, (iii) monitor for rapid variability of the X-ray absorber and (iv) use the unique high spectral and spatial resolution of the Chandra/HETG to distinguish between the photoionized and collisionally ionized circumnuclear matter around NGC 1365.

Title: Dawn of a quasar: the exceptional variability of IRAS 00397-1312

We propose a Chandra monitoring of four 15 ks observations of IRAS 00397-1312, the most luminous source in the 1 Jy ULIRG sample (L_IR~10^13 Lsun), which revealed a spectacular change in its observed X-ray emission: only a weak, soft emission was detected in a Chandra observation of June 2010, consistent with the starburst emission estimated from mid-IR spectroscopy, while a subsequent Suzaku observation in Dec 2010 revealed the direct emission of a quasar with a 300 times higher 2-10 keV luminosity (2x10^44 erg/s). This suggests that we are catching this extreme object in the key evolutionary phase when the quasar is cleaning out its way through the circumnuclear gas. A few new short X-ray observations spread across several months will be enough to constrain these physical scenarios.

Title: Inverse-Compton Emission from the Lobes of Powerful High-Redshift Radio Galaxies

Analysis of the radio synchrotron and X-ray inverse-Compton (IC) emission from powerful radio-loud AGNs allows us to determine their particle acceleration processes and electron energy spectra. We propose new Chandra observations of three bright FRII radio galaxies at z > 2.35, which will detect IC emission from the radio lobes and thermal emission, if any, from the hot phase of the ambient medium. Combining the X-ray observations with archival multi-frequency radio, VLA/GMRT observations, we will not only put constraints on the densities of the electrons emitting via synchrotron radiation in the radio and IC emission in the X-ray, but also understand the interplay between the ambient medium and the radio galaxy, and describe the properties of the particle energy spectrum in the lobe.

Title: Probing the Early Evolution of Galaxies and Massive Black Holes With Nearby Star-Forming Dwarfs

PI Name: Amy Reines

Supermassive black holes inhabit essentially all galaxies with bulges, yet the birth and growth of the first high-z black holes is poorly constrained. Reines et al. (2011) have recently discovered a low-luminosity AGN (LLAGN) in the bulgeless dwarf starburst galaxy Henize 2-10, offering the first opportunity to study a growing black hole in a nearby galaxy much like those in the earlier universe. Our proposal aims to determine if LLAGN are common in galaxies like Henize 2-10, and to characterize the properties of these local analogues of primordial black hole growth. Using Chandra and the EVLA, we will probe the first radio-selected sample of star-forming blue compact dwarfs for LLAGN, with immediate implications for our understanding of the early stages of galaxy and black hole evolution.

Title: Probing the High End of the Quasar Black Hole Mass Function

PI Name: Monica Young

High-mass (M > 10^9.5 solar masses) supermassive black holes accreting at rates significantly below Eddington (L/L_Edd < 3%) offer a glimpse of the final stage of black hole growth and evolution. Characterizing the X-ray properties of such a sample will probe the accretion structure under the extreme conditions found on the high end of the quasar black hole mass function. We propose Chandra observations of 7 quasars at z~0.5-1 in order to measure their X-ray flux, spectral shape, and intrinsic absorption. These measurements will constrain two key correlations between X-ray properties and accretion rate and provide insight into changes in the accretion disk/corona structure at low accretion rates.

Title: Try Again to Locate the Site of TeV Flaring in M87

PI Name: Daniel Harris

From observational data from VERITAS, HESS, and MAGIC, it appears that there are TeV high states for M87 which can last a few weeks and provide many nightly detections at a level significantly higher than the quiet state . Because we model the TeV emission as IC scattering by the same electrons responsible for X-ray synchrotron emission, we expect that TeV variability will be mirrored in the UV and X-rays. To determine the location of TeV emission and to obtain quasi simultaneous photometry to refine sync/IC calculations, we request a Chandra ToO program on M87 to be triggered by the TeV high state condition. We request a maximum of 90 ks, divided into 5ks observations so as to construct a lightcurve for comparison with those obtained by the Cherenkov observatories.

Title: Quasar Feedback in Action: The Wide-Angle Wind of Mrk 231

PI Name: Sylvain Veilleux

In recent months, our group has discovered a ~1000-km/s outflow in the nearest post-merger quasar Mrk 231 with mass outflow rate about 3x the star formation rate. This outflow extends over several kpc and is wide-angle, thus driven by a QSO wind rather than a jet. This powerful outflow may be the long-sought "smoking gun" of quasar mechanical feedback purported to transform gas-rich mergers into red and dead galaxies. We propose a 400-ksec ACIS-S observation of Mrk 231 to permit 2D spectral mapping of this QSO wind in the X-rays. The obscuring material in Mrk 231 will act as a natural coronagraph to help us study the faint X-ray nebula around the quasar. These data will also be used to monitor the central energy source and constrain the location of the obscuring / scattering material.

We request a combination of ACIS-S (200 ks total) and HST/WFC3 (10 orbits total) observations of 10 galaxies that ground-based observations indicate likely host two kpc-scale separation AGN, known as "dual AGN". Each target has double-peaked, spatially offset AGN emission lines suggestive of dual AGN, but ACIS-S detections of two X-ray point sources would be definitive proof of dual AGN. Complementary WFC3 imaging of the host galaxies would reveal details of the galaxy mergers that produce dual AGN. Combined, the ACIS-S and WFC3 observations would establish a powerful new technique for identifying large numbers of dual AGN with ground-based observations, and have important implications for understanding galaxy evolution, black hole growth, and the parent population of LISA sources.

Title: Variability and particle acceleration in the jet of Pictor A

PI Name: Martin Hardcastle

Pictor A is one of the closest FRII radio galaxies and one of a very few to show a continuous, bright, 100-kpc-scale X-ray jet. It is a key object for our understanding of powerful jets in general, and is of particular importance because of the jet variability seen in our existing observations. Regions of the jet at distances of tens of kpc have varied in the X-ray on a timescale of years, meaning that X-rays can come from very compact sub-regions of the jet, with strong implications for the location and nature of particle acceleration. This MCOP will pin down the timescales, location and spectral properties of the flaring regions in the jet; the data taken for this purpose will facilitate many other important scientific projects and will have high legacy value.

Title: Energy Dependent Microlensing in X-rays

PI Name: Xinyu Dai

We will use microlensing, where the stars in the lens galaxy magnify the accretion disk of a gravitationally lensed quasar, to improve estimates of the size of X-ray emission regions as a function of energy. While we have clearly detected energy-dependent microlensing, precision results require constraining the overall structure of the microlensing magnification patterns on the longer time scales (years) over which they vary. We focus on extending by two epochs the light curves of two ``active'' systems, RXJ1131-1231 and Q2237+0305, that show energy-dependent X-ray microlensing using integration times long enough to measure X-ray fluxes in 3 energy bands. These observations can only be done with Chandra because future X-ray observatories will lack the necessary angular resolution.

Title: Keeping Tabs on the Unique Jet in M87

We request 2 observations of the M87 jet at 5 ks each. The first should be in 2011Dec (the beginning of the "TeV M87 Season") and the second in 2012 March (halfway through the season). There are two reasons for this modest proposal. The first is that if our M87 ToO (proposal # 13700578) is triggered, we can understand the results much better if we have some idea as to the intensity of each component in the jet before the onset of TeV flaring. The other reason is to ascertain if the nucleus, the highly variable knot HST-1, or knot D (known to be variable in the optical) have increased substantially since the last time we obtained Chandra data (2010 April). If we were to find a substantial change, a DDT request would be instigated.

Title: The Most Accessible Quasar Feeding and Feedback Laboratory

PI Name: Kevin Schawinski

Less than 200,000 years ago, the nearby (z=0.05) galaxy IC 2497 hosted a powerful L_bol ~1E46 erg/s quasar, the nearest to us. The giant ionization nebula known as Hanny's Voorwerp preserves the light echo of the now dormant quasar's prior energy output. The rapid shutdown of the optically bright quasar in IC 2497 provides the first observed case of the shutdown of a quasar and raises a number of questions regarding the present day accretion state of the black hole. Circumstantial evidence points to a switch in accretion state to a radiatively inefficient state as is routinely see in Galactic X-ray binaries. We propose to use Chandra to search for evidence of a kinetic outflow driven by the present day, optically dull low-luminosity AGN in IC 2497.

Title: A DIRECT TEST OF AGN FEEDBACK IN LATE-TYPE GALAXIES: SPATIALLY RESOLVED HETG SPECTROSCOPY OF NGC 3393

PI Name: Daniel Evans

We propose a 350-ks Chandra/HETG observation of the prototypical massive late-type galaxy NGC 3393, in order to (1) map the kinematics of the NLR, and (2) directly measure the mass outflow rate from the AGN. We will use extract, compare, and model the photoionized emission-line spectra at multiple off-nuclear points along the NLR and ENLR, constructing a picture of how the AGN imparts its energy into its environment. We will also use a novel technique to map the velocity field of the kpc-scale gas, directly constraining the spatial extent and impact of any AGN outflow. Our observations will provide the key test of whether or not outflows in such late-type galaxies expel significant quantities of material during their hosts' transition from the blue cloud to the red sequence.

Title: Black Holes at the Centers of Nearby Dwarf Galaxies

PI Name: Edward Moran

As part of a search for intermediate-mass black holes in the local universe, we have assembled a sample of 27 AGNs in dwarf galaxies with absolute magnitudes as faint as -15.5 and stellar masses as low as 4e8 M_sun. Collectively, these are the least massive galaxies known to contain central black holes. Surprisingly, 25 of the objects are narrow-line (type 2) AGNs. As such, they are important in the context of theoretical work, which suggests that at low luminosites AGNs may lack obscuring tori and/or classical broad-line regions. X-ray data will indicate directly whether the AGNs are obscured. The data will also afford measurements of their high-energy luminosities, which will anchor their spectral energy distributions and provide constraints on their black-hole masses.

Title: CHANDRA ToO OBSERVATIONS OF FLARING FERMI BLAZARS

PI Name: Greg Madejski

We propose for two 10 ks ToO Chandra observations of blazars (or any other high latitude sources) undergoing an exceptional flare in the Fermi gamma-ray band. We intend to use Chandra only if observations with other facilities such as Suzaku or Swift are not sufficiently sensitive, or cannot reach the source because of the Solar angle or scheduling constraints. The positional information will be crucial in securing source identification, and resulting X-ray spectrum (and possibly variability) information will be indispensable to determine the emission mechanisms, and by extension, allow inferences about the structure of the sub-parsec jet, and connection of the jet to the accretion disk and the supermassive black hole.

Title: Investigating the Coeval Growth of SMBHs and Galaxies in a z = 2.23 Overdense Region

PI Name: Bret Lehmer

We propose to conduct a 100 ks observation of the 2QZClus1004+00 region, a rich H-alpha selected overdensity at z = 2.23 that is located between a highly-clustered group of four quasars (within a 14' X 14' region) selected for the 2dF survey. Using this sample and an identically-selected sample of z = 2.23 H-alpha emitters found over the ~1 deg^2 Chandra COSMOS region, we will investigate how the concurrent growth of galaxies and their SMBHs depend on environment.

Title: Chandra observations of the faintest hard X-ray sources in the SIX survey

PI Name: Eugenio Bottacini

We propose 5 ksec Chandra observations of each of the 20 AGN missing the NH-measurement and detected in the joined Swift-INTEGRAL hard X-ray (SIX) survey, obtained merging the Swift/BAT and the INTEGRAL-ISGRI surveys. The SIX survey is the deepest hard X-ray survey to date. It samples fluxes of the order ~10^-12 erg cm^-2 s^-1 above 15 keV and it detects 130 sources within 6200 deg^2 sky area. Chandra observations are required to unveil the nature of this unique sample of sources. The sources are likely highly absorbed. Chandra will allow to pin-point the optical counterpart of the high energy source with a very good precision together with accurate luminosity and NH determination.
