Silicon X-ray absorption in the Galactic ISM: the gaseous component
E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +3
We present a detailed analysis of the gaseous component of the Si K edge using high-resolution Chandra spectra of low-mass X-ray binaries. We fit the spectra with amodified version…
Oxygen, neon, and iron X-ray absorption in the local interstellar medium
Efraín Gatuzz, Javier A. García, Timothy R. Kallman +1
We present a detailed study of X-ray absorption in the local interstellar medium by analyzing the X-ray spectra of 24 galactic sources obtained with the {\it Chandra} High Energy T…
ISMabs: a comprehensive X-ray absorption model for the interstellar medium
E. Gatuzz, J. García, T. R. Kallman +2
We present an X-ray absorption model for the interstellar medium, to be referred to as ISMabs, that takes into account both neutral and ionized species of cosmically abundant eleme…
Modeling the oxygen K absorption in the interstellar medium: an {\it XMM}-Newton view of Sco X-1
J. García, J. M. Ramírez, T. R. Kallman +5
We investigate the absorption structure of the oxygen in the interstellar medium by analyzing {\it XMM}-Newton observations of the low mass X-ray binary Sco X-1. We use simple mode…
Spectrum Synthesis Modeling of the X-ray Spectrum of GRO J1655-40 Taken During the 2005 Outburst
T. R. Kallman, M. A. Bautista, Stephane Goriely +5
The spectrum from the black hole X-ray transient GRO J1655-40. obtained using the High Energy Transmission Grating (HETG) in 2005 is notable as a laboratory for the study…
