Connection between the Accretion Disk and Jet in the Radio Galaxy 3C 111
Ritaban Chatterjee, Alan P. Marscher, Svetlana G. Jorstad +13
We present the results of extensive multi-frequency monitoring of the radio galaxy 3C 111 between 2004 and 2010 at X-ray (2.4--10 keV), optical (R band), and radio (14.5, 37, and 2…
An Occultation Event in Centaurus A and the Clumpy Torus Model
Elizabeth Rivers, Alex Markowitz, Richard Rothschild
We have analyzed 16 months of sustained monitoring observations of Cen A from the Rossi X-ray Timing Explorer to search for changes in the absorbing column in the line of sight to…
Tracking the Complex Absorption in NGC 2110 with Two Suzaku Observations
Elizabeth Rivers, Alex Markowitz, Richard Rothschild +6
We present spectral analysis of two Suzaku observations of the Seyfert 2 galaxy, NGC 2110. This source has been known to show complex, variable absorption which we study in depth b…
Emitting electrons and source activity in Markarian 501
Nijil Mankuzhiyil, Stefano Ansoldi, Massimo Persic +3
We study the variation of the broad-band spectral energy distribution (SED) of the BL Lac object Mrk 501 as a function of source activity, from quiescent to flaring. Through chi-sq…
Spectral Survey of X-Ray Bright Active Galactic Nuclei from the Rossi X-ray Timing Explorer
Elizabeth Rivers, Alex Markowitz, Richard Rothschild
Using long-term monitoring data from the Rossi X-ray Timing Explorer (RXTE), we have selected 23 active galactic nuclei (AGN) with sufficient brightness and overall observation tim…
Twelve and a Half Years of Observations of Centaurus A with RXTE
Richard E. Rothschild, Alex Markowitz, Elizabeth Rivers +5
The Rossi X-ray Timing Explorer has observed the nearest radio galaxy, Centaurus A, in 13 intervals from 1966 August to 2009 February over the 3--200 keV band. Spectra accumulated…
