Line-of-sight gas sloshing in the cool core of Abell 907
Shutaro Ueda, Yuto Ichinohe, Tetsu Kitayama +1
We present line-of-sight gas sloshing first found in a cool core in a galaxy cluster. The galaxy cluster Abell 907 is identified as a relaxed cluster owing to its global X-ray surf…
Substructures associated with the sloshing cold front in the Perseus cluster
Y. Ichinohe, A. Simionescu, N. Werner +2
X-ray substructures in clusters of galaxies provide indirect clues about the microphysical properties of the intracluster medium (ICM), which are still not very well known. In orde…
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…
CAMELOT: design and performance verification of the detector concept and localization capability
Masanori Ohno, Norbert Werner, András Pál +16
A fleet of nanosatellites using precise timing synchronization provided by the Global Positioning System is a new concept for monitoring the gamma-ray sky that can achieve both all…
CAMELOT - Concept study and early results for onboard data processing and GPS-based timestamping
András Pál, László Mészáros, Norbert Tarcai +17
Due to recent advances in nanosatellite technology, it is now feasible to integrate scintillators with an effective area of hundreds of square-centimeters on a single three-unit cu…
CAMELOT: Cubesats Applied for MEasuring and LOcalising Transients - Mission Overview
Norbert Werner, Jakub Řípa, András Pál +17
We propose a fleet of nanosatellites to perform an all-sky monitoring and timing based localisation of gamma-ray transients. The fleet of at least nine 3U cubesats shall be equippe…
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…
Imaging and spectral performance of CdTe double-sided strip detectors for the Hard X-ray Imager onboard ASTRO-H
Kouichi Hagino, Hirokazu Odaka, Goro Sato +20
The imaging and spectral performance of CdTe double-sided strip detectors (CdTe-DSDs) was evaluated for the ASTRO-H mission. The charcterized CdTe-DSDs have a strip pitch of 0.25 m…
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…
X-ray properties of high-richness CAMIRA clusters in the Hyper Suprime-Cam Subaru Strategic Program field
Naomi Ota, Ikuyuki Mitsuishi, Yasunori Babazaki +13
We present the first results of a pilot X-ray study of 37 rich galaxy clusters at in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) field. Diffuse X-ray emiss…
Neural network-based preprocessing to estimate the parameters of the X-ray emission of a single-temperature thermal plasma
Y. Ichinohe, S. Yamada, N. Miyazaki +1
We present data preprocessing based on an artificial neural network to estimate the parameters of the X-ray emission spectra of a single-temperature thermal plasma. The method find…
