The Suzaku view of the disk-jet connection in the low-excitation radio galaxy NGC 6251
(2011-11)
We present results from an 87 ks Suzaku observation of the canonical low-excitation radio galaxy (LERG) NGC6251. We have previously suggested that LERGs violate conventional active galactic nucleus unification schemes: ...
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 ...
The gas dynamics of NGC 4472 revealed by XMM-Newton
(2011)
We present results from a 100 ks XMM-Newton observation of the hot gas in the Virgo cluster elliptical galaxy NGC 4472. We find a surface brightness discontinuity ∼21 kpc north of the nucleus, consistent with being a contact ...
