SPEX: High-Resolution Spectral Modeling and Fitting for X-ray Astronomy
Jelle de Plaa, Jelle S. Kaastra, Liyi Gu +2
We present the SPEX software package for modeling and fitting X-ray spectra. Our group has developed spectral models, atomic data and code for X-ray applications since the 1970's.…
The impact of improved plasma diagnostics on modeling the X-ray Universe
Junjie Mao, Francois Mernier, Jelle S. Kaastra +3
The high-resolution X-ray spectrum of the Perseus galaxy cluster observed with the Hitomi satellite challenges astrophysical collisional ionized plasma models that are widely used…
Observations of a Pre-Merger Shock in Colliding Clusters of Galaxies
Liyi Gu, Hiroki Akamatsu, Timothy W. Shimwell +10
Clusters of galaxies are the largest known gravitationally-bound structures in the Universe. When clusters collide, they create merger shocks on cosmological scales, which transfor…
X-ray spectra of the Fe-L complex
Liyi Gu, A. J. J. Raassen, Junjie Mao +7
The Hitomi results on the Perseus cluster lead to improvements in our knowledge of atomic physics which are crucial for the precise diagnostic of hot astrophysical plasma observed…
Constraining Gas Motions in the Intra-Cluster Medium
A. Simionescu, J. ZuHone, I. Zhuravleva +9
The detailed velocity structure of the diffuse X-ray emitting intra-cluster medium (ICM) remains one of the last missing key ingredients in understanding the microphysical properti…
