Non-stationary variability in AGN: the case of 3C 390.3
M. Gliozzi, I. E. Papadakis, R. M. Sambruna +1
We use data from a two-year intensive RXTE monitoring campaign of the broad-line radio galaxy 3C 390.3 to investigate its stationarity. In order to exploit the potential informatio…
An Exploratory Chandra survey of Large Bright Quasar Survey broad absorption line QSOs
S. C. Gallagher, W. N. Brandt, G. Chartas +1
We are in the process of obtaining a complete sample of exploratory X-ray observations of broad absorption line (BAL) QSOs from the Large Bright Quasar Survey (LBQS). This survey i…
Emission Line Diagnostics of Accretion Flows in Weak-Line Radio Galaxies
Karen T. Lewis, Michael Eracleous, Rita M. Sambruna
In recent surveys of Radio-loud AGN, a new sub-class of objects, known as Weak-Line Radio Galaxies (WLRGs) has emerged. These radio galaxies have only weak, low-ionization optical…
Discovery of Narrow X-ray Absorption Lines from NGC 3783 with the Chandra HETGS
Shai Kaspi, W. N. Brandt, Hagai Netzer +4
We present the first grating-resolution X-ray spectra of the Seyfert 1 galaxy NGC 3783, obtained with the High Energy Transmission Grating Spectrometer on the Chandra X-ray Observa…
Coordinated RXTE and multiwavelength observations of blazars
Rita M. Sambruna
Results from recent multiwavelength observations of blazars are reviewed, with particular emphasis on those involving the Rossi X-ray Timing Explorer (RXTE). I discuss blazars' spe…
Blazars: Clues to jet physics
Rita M. Sambruna
Being dominated by non-thermal emission from aligned relativistic jets, blazars allow us to elucidate the physics of extragalactic jets, and, ultimately, how energy is extracted fr…
