SUMMARY OF SEQUENCE NUMBER 800063
Title: BRIGHT ELLIPTICAL GALAXIES AND HIGH REDSHIFT CLUSTERS
Observer: MUSHOTZKY
Subject Category: Clusters of Galaxies
Seq: 800063 ObsId: 00325
Long-term Plan bin: no LTS bin
ABSTRACT
The program consists of 1) detailed spatially resolved spectra of bright elliptical galaxies and 2) deep images of high redshift cluster candidates NGC4472,NGC4636 and NGC 4472 are 3 of the brightest x-ray elliptical galaxies. The AXAF exposure times with ACIS-S are set to derive temperature and abundance profiles for >3 annuli inside the deVacouleurs radius allowing a direct comparison of the gas and stellar abundances and the gas and stellar temperatures. These deep exposures should also detect numerous x-ray binaries in these galaxies. 3C324 is a z=1.2 cluster that is the most distant x-ray cluster known. The S-Z cluster 1312+42 is one of two objects for which a significant Sunyaev-Zeldovich decrement is measured but for which there is no optical cluster visible.
