XMM-Newton EPIC and OM Observations of Her X-1 over the 35 d Beat Period and an Anomalous Low State
S. Zane, G. Ramsay, M. A. Jimenez-Garate +4
We present the results of a series of XMM-Newton EPIC and OM observations of Her X-1, spread over a wide range of the 35 d precession period. We confirm that the spin modulation of…
Identification of an Extended Accretion Disk Corona in the Hercules X-1 Low State: Moderate Optical Depth, Precise Density Determination, and Verification of CNO Abundances
Mario A. Jimenez-Garate, John C. Raymond, Duane A. Liedahl +1
We identify an accretion disk atmosphere and corona from the high resolution X-ray spectrum of Hercules X-1, and we determine its detailed physical properties. More than two dozen…
Atomic X-Ray Spectra of Accretion Disk Atmospheres in the Kerr Metric
Mario A. Jimenez-Garate, Duane A. Liedahl, Christopher W. Mauche +1
We calculate the atmospheric structure of an accretion disk around a Kerr black hole and obtain its X-ray spectrum, which exhibits prominent atomic transitions under certain circum…
Using the X-ray Emission Lines of Seyfert 2 AGN to Measure Abundance Ratios
Mario A. Jimenez-Garate, Toan Khu
We measure the metal abundance ratios in the X-ray photoionized gas located near the narrow line region of a sample of Seyfert 2 AGN. The high-resolution X-ray spectra observed wit…
XMM-Newton EPIC & OM observations of Her X-1 over the 35 day beat period
Silvia Zane, Gavin Ramsay, Mario A. Jimenez-Garate +2
We present the results of a series of XMM-Newton EPIC and OM observations of Her X-1, spread over a wide range of the 35 day precession period. We confirm that the spin modulation…
Reprocessing of Soft X-ray Emission Lines in Black Hole Accretion Disks
Christopher W. Mauche, Duane A. Liedahl, Benjamin F. Mathiesen +2
By means of a Monte Carlo code that accounts for Compton scattering and photoabsorption followed by recombination, we have investigated the radiation transfer of Ly alpha, He alpha…
