Chandra Proposal Id #06611057

Scientific paper

We selected a sample of 13 X-ray bright early-type galaxies with detected radio emission for short ACIS observations. The four primary aims of our snapshot survey are 1) to identify systems for possible future deep Chandra observations, 2) to measure the mechanical energy provided by a radio source of a given luminosity, 3) to conduct a census of these systems to determine the fraction that currently show evidence of interactions of the radio plasma with the X-ray gas, and 4) to measure the X-ray emission from the nucleus and compare this with the estimated mass of the supermassive black hole. We will compare results from this galaxy sample to those from cluster samples. The proposed ACIS ``snapshots'' of NGC4104 and NGC7196 will complete the sample of 13 galaxies.
