Halo Concentration, Galaxy Red Fraction, and Gas Properties of Optically-defined Merging Clusters
Nobuhiro Okabe, Masamune Oguri, Hiroki Akamatsu +9
We present multi-wavelength studies of optically-defined merging clusters, based on the Hyper Suprime-Cam Subaru Strategic Program. Luminous red galaxies, tracing cluster mass dist…
High entropy and evidence for a merger in the low surface brightness cluster Abell 2399
Ikuyuki Mitsuishi, Yasunori Babazaki, Naomi Ota +4
We present results of the X-ray analyses of the nearby cluster of galaxies Abell 2399 () using the XMM-Newton and Suzaku satellites. This cluster is classified as a low su…
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…
Hot Grain Dynamics by Electric Charging and Magnetic Trapping in Debris Disks
Hiroshi Kimura, Masanobu Kunitomo, Takeru K. Suzuki +3
The recent discovery of hot dust grains in the vicinity of main-sequence stars has become a hot issue among the scientific community of debris disks. Hot grains must have been enor…
A Spatially Resolved Study of X-ray Properties in Superbubble 30 Dor C with
Yasunori Babazaki, Ikuyuki Mitsuishi, Hironori Matsumoto +4
We carry out spatially resolved spectral analysis with a physical scale of 10 pc in X-ray for the superbubble 30 Dor C, which has the largest diameter of 80 pc and the…
Possible Evidence for Cosmic-Ray Acceleration in the Type Ia SNR RCW 86: Spatial Correlation between TeV Gamma rays and Interstellar Atomic Protons
H. Sano, G. Rowell, E. M. Reynoso +13
We present a detailed morphological study of TeV gamma rays, synchrotron radiation, and interstellar gas in the young Type Ia supernova remnant (SNR) RCW 86. We find that the inter…
Suzaku Observations of Low Surface Brightness Cluster Abell 1631
Yasunori Babazaki, Ikuyuki Mitsuishi, Naomi Ota +5
We present analysis results for a nearby galaxy cluster Abell 1631 at using the X-ray observatory Suzaku. This cluster is categorized as a low X-ray surface brightness…
Inorbit Performance of the Hard X-ray Telescope (HXT) on board the Hitomi (ASTRO-H) satellite
H. Matsumoto, H. Awaki, M. Ishida +16
Hitomi (ASTRO-H) carries two Hard X-ray Telescopes (HXTs) that can focus X-rays up to 80 keV. Combined with the Hard X-ray Imagers (HXIs) that detect the focused X-rays, imaging sp…
A large sample of shear selected clusters from the Hyper Suprime-Cam Subaru Strategic Program S16A wide field mass maps
Satoshi Miyazaki, Masamune Oguri, Takashi Hamana +13
We present the result of searching for clusters of galaxies based on weak gravitational lensing analysis of the ~deg area surveyed by Hyper Suprime-Cam (HSC) as a Sub…
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…
