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…
A Comprehensive X-ray Absorption Model for Atomic Oxygen
T. W. Gorczyca, M. A. Bautista, M. F. Hasoglu +9
An analytical formula is developed to represent accurately the photoabsorption cross section of O I for all energies of interest in X-ray spectral modeling. In the vicinity of the…
Time-dependent Photoionization of Gaseous Nebulae: the Pure Hydrogen Case
J. García, E. E. Elhoussieny, M. A. Bautista +1
We study the problem of time-dependent photoionization of low density gaseous nebulae subjected to sudden changes in the intensity of ionizing radiation. To this end, we write a co…
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…
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…
X-ray reflected spectra from accretion disk models. III. A complete grid of ionized reflection calculations
J. Garcia, T. Dauser, C. S. Reynolds +4
We present a new and complete library of synthetic spectra for modeling the component of emission that is reflected from an illuminated accretion disk. The spectra were computed us…
