Broadband spectroscopy using two Suzaku observation of the HMXB GX 301-2

Slawomir Suchy, Felix Fuerst, Katja Pottschmidt +5

We present the analysis of two Suzaku observations of GX 301-2 at two orbital phases after the periastron passage. Variations in the column density of the line-of-sight absorber ar…

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…

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…

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…
