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…
Solar abundance ratios of the iron-peak elements in the Perseus Cluster
Hitomi Collaboration
The metal abundance of the hot plasma that permeates galaxy clusters represents the accumulation of heavy elements produced by billions of supernovae. Therefore, X-ray spectroscopy…
Suzaku and XMM-Newton Observations of the North Polar Spur: Charge Exchange or ISM Absorption?
Liyi Gu, Junjie Mao, Elisa Costantini +1
By revisiting the Suzaku and XMM-Newton data of the North Polar Spur, we discovered that the spectra are inconsistent with the traditional model consisting of pure thermal emission…
The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster
Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215
High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
