Photoionization Modeling and the K Lines of Iron

Kallman, T. R.; Krolik, J. H.; Bautista, M. A. +2 more

We calculate the efficiency of iron K line emission and iron K absorption in photoionized models using a new set of atomic data. These data are more comprehensive than those previously applied to the modeling of iron K lines from photoionized gases and allow us to systematically examine the behavior of the properties of line emission and absorptio…

An Extended Scheme for Fitting X-Ray Data with Accretion Disk Spectra in the Strong Gravity Regime

Yaqoob, T.; Dovčiak, M.; Karas, V.

Accreting black holes are believed to emit X-rays, which then mediate information about strong gravity in the vicinity of the emission region. We report on a set of new routines for the XSPEC package for analyzing X-ray spectra of black-hole accretion disks. The new computational tool significantly extends the capabilities of the currently availab…

The Nature of Luminous X-Ray Sources with Mid-Infrared Counterparts

Le Floc'h, E.; Barmby, P.; Dole, H. +28 more

We investigate the luminous X-ray sources in the Lockman Hole (LH) and the extended Groth strip (EGS) detected at 24 µm using the Multiband Imaging Photometer (MIPS) and also with the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope. We assemble optical/infrared spectral energy distributions (SEDs) for 45 X-ray/24 µm s…
