XRISM spectroscopy of a crowded Galactic center region -- I. Disentangling the sources in the field of view
Maxime Parra, Kai Matsunaga, Shifra Mandel +16
The Galactic center is a complex and crowded region hosting the supermassive black hole Sgr A*, numerous accreting compact objects, and diffuse X-ray emission. This paper presents…

XRISM spectroscopy of a crowded Galactic center region -- II. Narrow emission lines in the Black Hole candidate MAXI J1744-294/Swift J174540.2-290037
Maxime Parra, Shifra Mandel, Kai Matsunaga +13
Narrow, highly ionized X-ray emission lines in black hole low-mass X-ray binaries (BH-LMXBs) are rare and have been observed in only a few sources, during unusual, heavily obscured…

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…
