X-ray Emitting GHz-Peaked Spectrum Galaxies: Testing a Dynamical-Radiative Model with Broad-Band Spectra
L. Ostorero, R. Moderski, L. Stawarz +6
In a dynamical-radiative model we recently developed to describe the physics of compact, GHz-Peaked-Spectrum (GPS) sources, the relativistic jets propagate across the inner, kpc-si…
Self-gravitating fragmentation of eccentric accretion disks
R. D. Alexander, P. J. Armitage, J. Cuadra +1
We consider the effects of eccentricity on the fragmentation of gravitationally unstable accretion disks, using numerical hydrodynamics. We find that eccentricity does not affect t…
RXTE Observation of Cygnus X--1: III. Implications for Compton Corona and ADAF Models
Michael A. Nowak, Joern Wilms, Brian A. Vaughan +2
We have recently shown that a `sphere+disk' geometry Compton corona model provides a good description of Rossi X-ray Timing Explorer (RXTE) observations of the hard/low state of Cy…
HST Observations of the Broad Absorption Line Quasar PG 0946+301
Nahum Arav, Kirk T. Korista, Martijn de Kool +2
We analyze HST and ground based spectra of the brightest BALQSO in the UV: PG~0946+301. A detailed study of the absorption troughs as a function of velocity is presented, facilitat…
RXTE Observation of Cygnus X-1: II. Timing Analysis
Michael A. Nowak, Brian A. Vaughan, Joern Wilms +2
We present timing analysis for a Rossi X-ray Timing Explorer observation of Cygnus X-1 in its hard/low state. This was the first RXTE observation of Cyg X-1 taken after it transite…
The Origin of Warped, Precessing Disks in X-Ray Binaries
Philip R. Maloney, Mitchell C. Begelman
The radiation-driven warping instability discovered by Pringle holds considerable promise as the mechanism responsible for producing warped, precessing accretion disks in X-ray bin…
