Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
The XRISM/Resolve view of the Fe K region of Cyg X-3
XRISM Collaboration
The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes th…
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…
Supernova Archaeology with X-Ray Binary Winds -- The Case of GRO J1655-40
Noa Keshet, Ehud Behar, Timothy R. Kallman
Supernovae are responsible for the elemental enrichment of the galaxy and some are postulated to leave behind a black hole. In a stellar binary system the supernova pollutes its co…
Impact of the disk magnetization on MHD disk wind signature
Sudeb Ranjan Datta, Susmita Chakravorty, Jonathan Ferreira +8
Observation of blue-shifted X-ray absorption lines indicates the presence of wind from the accretion disk in X-ray binaries. Magnetohydrodynamic (MHD) driving is one of the possibl…
Elemental abundances in the diffuse ISM from joint FUV and X-ray spectroscopy: iron, oxygen, carbon and sulfur
I. Psaradaki, L. Corrales, J. Werk +10
In this study, we investigate interstellar absorption lines along the line of sight toward the galactic low-mass X-ray binary Cygnus X-2. We combine absorption line data obtained f…
High-Resolution X-Ray Spectroscopy of Interstellar Iron Toward Cygnus X-1 and GX 339-4
Lia Corrales, Eric V. Gotthelf, Efrain Gatuzz +7
We present a high-resolution spectral study of Fe L-shell extinction by the diffuse interstellar medium (ISM) in the direction of the X-ray binaries Cygnus X-1 and GX 339-4, using…
SRG/eROSITA 3D mapping of the ISM using X-ray absorption spectroscopy
E. Gatuzz, J. Wilms, A. Zainab +6
We present a detailed study of the hydrogen density distribution in the local interstellar medium (ISM) using the X-ray absorption technique. Hydrogen column densities were precise…
