VLBA and Chandra Observations of Jets in FRI radio galaxies: Constraints on Jet Evolution
P. Kharb, C. O'Dea, A. Tilak +5
(ABRIDGED) We present here the results from new Very Long Baseline Array observations at 1.6 and 5 GHz of 19 galaxies of a complete sample of 21 UGC FRI radio galaxies. New Chandra…
X-ray vs. water maser emission in AGN
P. Castangia, A. Tilak, M. Kadler +3
Correlations between X-ray and water maser emission in AGN have been recently reported. However, the lack of systematic studies affects the confidence level of these results. In th…
Discovery of Candidate HO Disk Masers in AGN and Estimations of Centripetal Accelerations
Lincoln J. Greenhill, Paul T. Kondratko, James M. Moran +1
Based on spectroscopic signatures, about one-third of known HO maser sources in active galactic nuclei (AGN) are believed to arise in highly inclined accretion disks around cen…
Prevalence of High X-ray Obscuring Columns among AGN that Host HO Masers
Lincoln J. Greenhill, Avanti Tilak, Grzegorz Madejski
Of 104 AGN known to exhibit HO maser emission, X-ray data that enable estimation of column densities, or lower limits, are available for 42. Contributing to this, we report ana…
A Deep 0.3-10 keV Spectrum of the HO Maser Galaxy IC 2560
Avanti Tilak, Lincoln Greenhill, Chris Done +1
We present a new XMM-Newton spectrum of the Seyfert 2 nucleus of IC 2560, which hosts HO maser emission from an inclined Keplerian accretion disk. The X-ray spectrum shows so…
Resolving the Shocks in Radio Galaxy Nebulae: HST and Radio Imaging of 3C 171, 3C277.3 and PKS2250-41
Avanti Tilak, Christopher P. O'Dea, Clive Tadhunter +5
We present the results of HST/WFPC2 medium and narrow band imaging and VLA and MERLIN2 radio imaging of three powerful radio galaxies: 3C 171, 3C 277.3, and PKS 2250-41. We obtaine…
