AGN heating in galaxy groups: A statistical study
N. N. Jetha, T. J. Ponman, M. J. Hardcastle +1
We present gas temperature, density, entropy and cooling time profiles for the cores of a sample of 15 galaxy groups observed with {\it Chandra}. We find that the entropy profiles…
Shock heating by nearby AGN
J. H. Croston, R. P. Kraft, M. J. Hardcastle
Shock heating by radio jets is potentially an important process in a range of environments, as it will increase the entropy of the heated gas. Although this process is expected to…
X-ray Constraints on Galaxy-Gas-Jet Interactions in the Dumbbell Galaxies NGC4782 and NGC4783 in the LGG316 Group
M. E. Machacek, R. P. Kraft, C. Jones +2
We present results from a 49.3 ks Chandra X-ray observation of the strongly interacting dumbbell galaxies NGC4782(3C278) and NGC4783 that constrain the kinematics of the interactio…
The Chandra, HST, and VLA View of the Circumnuclear Extended Emission in the Narrow Emission Line Galaxy NGC 2110
Daniel A. Evans, Julia C. Lee, Maria Kamenetska +4
We present results from new Chandra and archival HST and VLA imaging observations of the circumnuclear extended emission in the nearby Type 2 Seyfert galaxy NGC 2110. We find resol…
The X-ray nuclei of intermediate-redshift radio sources
M. J. Hardcastle, D. A. Evans, J. H. Croston
We present a Chandra and XMM-Newton spectral analysis of the nuclei of the radio galaxies and radio-loud quasars from the 3CRR sample in the redshift range 0.1 < z < 0.5. In the ra…
Jet Speeds in Wide Angle Tailed Radio Galaxies
Nazirah N. Jetha, Martin J. Hardcastle, Irini Sakelliou +1
We present a sample of 30 wide angle tailed radio galaxies (WATs) that we use to constrain the jet speeds in these sources. We measure the distribution of jet-sidedness ratios for…
