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…
L-shell Photoionisation Cross Sections in the S^{+}, S^{2+}, S^{3+} Isonuclear Sequence
J. -P. Mosnier, E. T. Kennedy, D. Cubaynes +6
We present absolute L-shell photoionisation cross sections for the S+, S2+, S3+ions. The cross sections were obtained using the monochromatised photon beam delivered by the SOLEIL…
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},…
The XSTAR Atomic Database
Claudio Mendoza, Manuel A. Bautista, Jérôme Deprince +7
We describe the atomic database of the XSTAR spectral modeling code, summarizing the systematic upgrades carried out in the past twenty years to enable the modeling of K lines from…
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…
