SUMMARY OF SEQUENCE NUMBER 700149

Title: THE X-RAY CLUSTER ENVIRONMENT OF BLAZARS

Observer: Pesce

Subject Category: Active Galaxies and Quasars

Seq: 700149 ObsId: 00844

Long-term Plan bin: no LTS bin

ABSTRACT

Blazars are an important class of AGN, offering a view of the energy producing region near the central black hole. They are often found in poor galaxy clusters, but intrinsic cluster properties are largely unknown. The environment may play a role in determining the different blazar types and can tell us more about the parent population. We propose to observe the environments of blazars with the AXAF ACIS-I imager. Our complete sample of 12 objects, unbiased with respect to the optical environment, spans all spectral energy distributions and luminosities. We will detect cluster gas to below the expected luminosity for poor clusters, and constrain its extent, temperature, mass, and density.
