Clear detection of dusty torus signatures in a weak-line radio galaxy: the case of PKS 0043-42
(2011-06)
We report the clearest detection to date of dusty torus signatures in a weak-line radio galaxy (WLRG). The deep Spitzer InfraRed Spectrograph (IRS) rest-frame mid-infrared (MIR) spectrum of the WLRG PKS 0043-42 (z = 0.116) ...
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 ...
