A self-consistent model of shock-heated plasma in non-equilibrium states for direct parameter constraints from X-ray observations

Yuken Ohshiro, Shunsuke Suzuki, Yoshizumi Okada +2

X-ray observations of shock-heated plasmas, such as those found in supernova remnants, often exhibit features of temperature and ionization non-equilibrium. For accurate interpreta…

Enrichment of the hot intracluster medium: observations

F. Mernier, V. Biffi, H. Yamaguchi +7

Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). Wi…

Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector

Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191

We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…

Constraints on the Chemical Enrichment History of the Perseus Cluster of Galaxies from High-Resolution X-ray Spectroscopy

A. Simionescu, S. Nakashima, H. Yamaguchi +32

High-resolution spectroscopy of the core of the Perseus Cluster of galaxies, using the satellite above 2 keV and the - Reflection Grating Spectrometer at lowe…

Hitomi X-ray Observation of the Pulsar Wind Nebula G21.50.9

Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +194

We present results from the Hitomi X-ray observation of a young composite-type supernova remnant (SNR) G21.50.9, whose emission is dominated by the pulsar wind nebula (PWN) cont…
