An X-ray survey of the 2 Jy sample-I : Is there an accretion mode dichotomy in radio-loud AGN?
(2014-05-01)
We carry out a systematic study of the X-ray emission from the active nuclei of the 0.02 < z< 0.7 2 Jy sample, using Chandra and XMM-Newton observations.We combine our results with those from mid-infrared, optical emission-line ...
Shocks, seyferts, and the supernova remnant connection : A chandra observation of the circinus galaxy
(2012-10-20)
We analyze new Chandra observations of the nearest (D = 4 Mpc) Seyfert 2 active galaxy, Circinus, and match them to pre-existing radio, infrared, and optical data to study the kpc-scale emission. The proximity of Circinus ...
Markarian 6 : shocking the environment of an intermediate Seyfert
(2011)
Markarian 6 is a nearby (D ~ 78 Mpc) Seyfert 1.5, early-type galaxy, with a double set of radio bubbles. The outer set spans similar to 7.5 kpc and is expanding into the halo regions of the host galaxy. We present an ...
A large-scale shock surrounding a powerful radio galaxy?
(2011)
We report Chandra evidence for a 200 kpc scale shock in the cluster surrounding the powerful radio galaxy 3C444. Our 20 ks observation allows us to identify a clear surface brightness drop around the outer edge of the radio ...
