A Chandra-HETG VIEW OF MCG +8-11-11
K. D. Murphy, M. A. Nowak
We present a spectral analysis of the 118 ks High Energy Transmission Gratings (HETG) observation of the X-ray bright Seyfert 1.5 galaxy MCG +8-11-11, in conjunction with 100 ks of…
Monte Carlo simulations of the Nickel K fluorescent emission line in a toroidal geometry
Tahir Yaqoob, Kendrah D. Murphy
We present new results from Monte Carlo calculations of the flux and equivalent width (EW) of the Ni Kalpha fluorescent emission line in the toroidal X-ray reprocessor model of Mur…
The energy budget for X-ray to infrared reprocessing in Compton-thin and Compton-thick active galaxies
Tahir Yaqoob, Kendrah D. Murphy
Heavily obscured active galactic nuclei (AGNs) play an important role in contributing to the cosmic X-ray background (CXRB). However, the AGNs found in deep X-ray surveys are often…
The Compton shoulder of the Fe Kalpha fluorescent emission line in active galactic nuclei
Tahir Yaqoob, Kendrah D. Murphy
We present new, high signal-to-noise ratio results from a Monte Carlo study of the properties of the Compton shoulder of the Fe Kalpha emission line in the toroidal X-ray reprocess…
NGC 2992 in an X-ray high state observed by XMM: Response of the Relativistic Fe K Line to the Continuum
X. W. Shu, T. Yaqoob, K. D. Murphy +3
We present the analysis of an XMM observation of the Seyfert galaxy NGC 2992. The source was found in its highest level of X-ray activity yet detected, a factor higher…
On the efficiency of production of the Fe Kalpha emission line in neutral matter
T. Yaqoob, K. D. Murphy, L. Miller +1
The absolute luminosity of the Fe Kalpha emission line from matter illuminated by X-rays in astrophysical sources is nontrivial to calculate except when the line-emitting medium is…
