Improved Reflection Models of Black-Hole Accretion Disks: Treating the Angular Distribution of X-rays
J. Garcia, T. Dauser, A. Lohfink +8
X-ray reflection models are used to constrain the properties of the accretion disk, such as the degree of ionization of the gas and the elemental abundances. In combination with ge…
An outburst scenario for the X-ray spectral variability in 3C 111
F. Tombesi, J. N. Reeves, C. S. Reynolds +2
We present a combined Suzaku and Swift BAT broad-band E=0.6-200keV spectral analysis of three 3C 111 observations obtained in 2010. The data are well described with an absorbed pow…
An X-Ray View of the Jet-Cycle in the Radio Loud AGN 3C120
Anne M. Lohfink, Christopher S. Reynolds, Svetlana G. Jorstad +10
We present a study of the central engine in the broad-line radio galaxy 3C120 using a multi-epoch analysis of a deep XMM-Newton observation and two deep Suzaku pointings (in 2012).…
Photoionization modeling of oxygen K absorption in the interstellar medium:the Chandra grating spectra of XTE J1817-330
E. Gatuzz, J. García, C. Mendoza +6
We present detailed analyses of oxygen K absorption in the interstellar medium (ISM) using four high-resolution Chandra spectra towards the X-ray low-mass binary XTE J1817-330. The…
Tackling the soft X-ray excess in AGN with variability studies
Anne M. Lohfink, Christopher S. Reynolds, Richard F. Mushotzky +1
The origin of the soft X-ray excess in AGN has been a mystery ever since its discovery. We present how the time variability of this spectral component can point towards its origin.…
