XRISM spectroscopy of a crowded Galactic center region -- III. S, Ar and Ca ISM Absorption Features in the spectrum of MAXI J1744-294
Efrain Gatuzz, Maxime Parra, Muhammet F. Hasoglu +7
We present a comprehensive study of X-ray absorption by sulfur (S), argon (Ar), and calcium (Ca) in the interstellar medium (ISM) along the line of sight to the low-mass X-ray bina…
Argon X-ray absorption in the local ISM
E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +2
We present the first comprehensive analysis of the argon K-edge absorption region (3.1-4.2 Å) using high-resolution HETGS {\it Chandra} spectra of 33 low-mas X-ray binaries. Utiliz…
Sulfur X-ray absorption in the local ISM
Efrain Gatuzz, T. W. Gorczyca, M. F. Hasoglu +3
We present a study S K-edge using high-resolution HETGS {\it Chandra} spectra of 36 low-mas X-ray binaries. For each source, we have estimated column densities for {\rm S}~{\sc i},…
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…
Carbon X-ray absorption in the local ISM: fingerprints in X-ray Novae spectra
E. Gatuzz, J. -U. Ness, T. W. Gorczyca +3
We present a study of the C K-edge using high-resolution LETGS Chandra spectra of four novae during their super-soft-source (SSS) phase. We identified absorption lines due to C~ii…
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…
