RXTE Investigation into Extended Hard X-ray Emission from Elliptical Galaxies
Michael Loewenstein, Azita Valinia, Richard Mushotzky
We present results of the first RXTE investigation of hard X-ray emission from normal elliptical galaxies. Joint spectral analysis of RXTE PCA and ASCA GIS data for NGC 4472 and NG…
On the Origin of the Iron K Line in the Spectrum of the Galactic X-ray Background
Azita Valinia, Vincent Tatischeff, Keith Arnaud +2
We propose a mechanism for the origin of the Galactic ridge X-ray background that naturally explains the properties of the Fe K line, specifically the detection of the centroid lin…
Hard X-ray Observation of Abell 496
Azita Valinia, Keith Arnaud, Michael Loewenstein +2
We report the results of hard X-ray observations of Abell 496 (A496), a nearby relaxed cluster, using the Rossi X-ray Timing Explorer (RXTE). The 3-20 keV spectrum of this cluster…
Structure of the Circumnuclear Region of Seyfert 2 Galaxies Revealed by RXTE Hard X-ray Observations of NGC 4945
G. M. Madejski, P. T. Zycki, C. Done +4
We report the Rossi X-ray Timing Explorer observations of the heavily absorbed Seyfert 2 galaxy NGC 4945, which confirm the large column density of the absorber, corresponding to t…
