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…
New Insights with XRISM & Cloudy: A novel Column Density Diagnostic
Chamani M. Gunasekera, Peter A. M. van Hoof, Masahiro Tsujimoto +1
We present a simple, yet powerful column density diagnostic for plasmas enabled by X-ray microcalorimeter observations. With the recent developments of the spectral simulation code…
Detection of the orbital modulation of Fe K fluorescence emission in Centaurus X-3 using the high-resolution spectrometer Resolve onboard XRISM
Yuto Mochizuki, Masahiro Tsujimoto, Richard L. Kelley +9
The Fe K fluorescence line emission in X-ray spectra is a powerful diagnostic tool for various astrophysical objects to reveal the distribution of cold matter around photo-ioniz…
Intrinsic line profiles for X-ray fluorescent lines in SKIRT
Bert Vander Meulen, Peter Camps, Masahiro Tsujimoto +1
We included the intrinsic line profiles of the strongest fluorescent lines in the X-ray radiative transfer code SKIRT to model the cold-gas structure and kinematics based on high-r…
High-velocity blue-shifted Fe XXV He line during a superflare of the RS CVn-type star IM Peg
Shun Inoue, Wataru Buz Iwakiri, Teruaki Enoto +8
Monitor of All-sky X-ray Image (MAXI) detected a superflare, releasing erg in 210 keV, of the RS CVn-type star IM Peg at 10:41 UT on 2023 July 23 with its Gas…
