Very Large Baseline Array observations of Mrk 6 : probing the jet-lobe connection
(2014-06-01)
We present the results of high-resolution VLBI (very long baseline interferometry) observations at 1.6 and 4.9 GHz of the radio-loud Seyfert galaxy, Mrk 6. These observations are able to detect a compact radio core in this ...
The nature of the jet-driven outflow in the radio galaxy 3C305
(2012-08-11)
We present Chandra X-ray and Very Large Array radio observations of the radio galaxy 3C305. The X-ray observations reveal the details of the previously known extended X-ray halo around the radio galaxy. We show using X-ray ...
Parsec-scale imaging of the radio-bubble Seyfert galaxy NGC 6764
(2010)
We have observed the composite active galactic nucleus (AGN)-starburst galaxy NGC 6764 with the Very Long Baseline Array at 1.6 and 4.9 GHz. These observations have detected a "core-jet" structure and a possible weak ...
Neutral Hydrogen (21 Centimeter) Absorption in Seyfert Galaxies: Evidence for Free-Free Absorption and Subkiloparsec Gaseous Disks
(1999)
Active galaxies are thought to be both fueled and obscured by neutral gas removed from the host galaxy and funneled into a central accretion disk. We performed a VLA imaging survey of 21 cm absorption in Seyfert and starburst ...
H 2O and OH Masers as Probes of the Obscuring Torus in NGC 1068
(1996)
We report the discovery of OH masers and positionally resolved H_2_O maser emission in the nucleus of NGC 1068. The brightest H_2_O masers are associated with the radio continuum component that is probably the location of ...
