H 2O and OH Masers as Probes of the Obscuring Torus in NGC 1068
Gallimore, J.F.; Baum, S.A.; O'Dea, C.P.; Brinks, E.; Pedlar, A. (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 ... -
MERLIN observations of neutral hydrogen absorption in the Seyfert nucleus of NGC 4151
Mundell, C.G.; Pedlar, A.; Baum, S.A.; O'Dea, C.P.; Gallimore, J.F.; Brinks, E. (1995-01-01) -
The nature of the jet-driven outflow in the radio galaxy 3C305
Hardcastle, M.J.; Massaro, F.; Harris, D.E.; O'Dea, C.P.; Siemiginowska, A.; Baum, S.A.; Bianchi, S.; Chiaberge, M.; Morganti, R. (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 ... -
Neutral Hydrogen (21 Centimeter) Absorption in Seyfert Galaxies: Evidence for Free-Free Absorption and Subkiloparsec Gaseous Disks
Gallimore, J.F.; Baum, S.A.; O'Dea, C.P.; Pedlar, A.; Brinks, E. (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 ... -
Neutral hydrogen absorption in NGC 1068 and NGC 3079
Gallimore, J.F.; Baum, S.A.; O'Dea, C.P.; Brinks, E.; Pedlar, A. (1994) -
Parsec-scale imaging of the radio-bubble Seyfert galaxy NGC 6764
Kharb, P.; Hota, A.; Croston, J.H.; Hardcastle, M.J.; O'Dea, C.P.; Kraft, R.P.; Axon, D.J.; Robinson, A. (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 ... -
Very Large Baseline Array observations of Mrk 6 : probing the jet-lobe connection
Kharb, P.; O'Dea, C.P.; Baum, S.A.; Hardcastle, M.J.; Dicken, D.; Croston, J. H.; Mingo, B.; Noel-Storr, J. (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 ...
