XRISM/Resolve observations of Hercules X-1: vertical structure and kinematics of the disk wind
Peter Kosec, Laura Brenneman, Erin Kara +11
X-ray binary accretion disk winds can carry away a significant fraction of the matter transferred from the companion and hence strongly affect the accretion flow and the long-term…
Variability of the X-ray obscuring wind in Mrk 335 with XMM-Newton/RGS
Daniele Rogantini, Erin Kara, Luigi Gallo +10
The paper analyzes X‑ray spectra of the Seyfert galaxy Mrk 335 to characterize a multi‑phase, clumpy accretion‑disk wind that shows strong variability on day‑scale timescales and a…
Atmospheric gas dynamics in the Perseus cluster observed with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +195
Extending the earlier measurements reported in Hitomi collaboration (2016, Nature, 535, 117), we examine the atmospheric gas motions within the central 100~kpc of the Perseus clust…
An X-ray spectroscopic search for dark matter and unidentified line signatures in the Perseus cluster with Hitomi
Takayuki Tamura, Andrew C. Fabian, Poshak Gandhi +14
We present results of a search for unidentified line emission and absorption signals in the 2-12keV energy band of spectra extracted from Perseus Cluster core region observations o…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Searching for cool and cooling X-ray emitting gas in 45 galaxy clusters and groups
Haonan Liu, Ciro Pinto, Andrew C. Fabian +2
We present a spectral analysis of cool and cooling gas in 45 cool-core clusters and groups of galaxies obtained from Reflection Grating Spectrometer (RGS) XMM- observations…
