Soft X-ray Imager aboard Hitomi (ASTRO-H)
Takaaki Tanaka, Hiroyuki Uchida, Hiroshi Nakajima +25
The Soft X-ray Imager (SXI) is an imaging spectrometer using charge-coupled devices (CCDs) aboard the Hitomi X-ray observatory. The SXI sensor has four CCDs with an imaging area si…
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…
Search for a Non-equilibrium Plasma in the Merging Galaxy Cluster Abell 754
Shota Inoue, Kiyoshi Hayashida, Shutaro Ueda +3
Abell 754 is a galaxy cluster in which an ongoing merger is evident on the plane of the sky, from the southeast to the northwest. We study the spatial variation of the X-ray spectr…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
Discovery of an Overlapping Cluster in Abell 1674 Field with Suzaku
Shota Inoue, Kiyoshi Hayashida, Hiroki Akamatsu +5
We present the results of a Suzaku observation of Abell 1674, an optically very rich (richness class 3) cluster cataloged as z = 0.1066. We discover the He-like Fe K-shell line fro…
Abundance Patterns in the Interstellar Medium of Early-type Galaxies Observed with Suzaku
Saori Konami, Kyoko Matsushita, Ryo Nagino +1
We have analyzed 17 early-type galaxies, 13 ellipticals and 4 S0's, observed with Suzaku, and investigated metal abundances (O, Mg, Si, and Fe) and abundance ratios (O/Fe, Mg/Fe, a…
Proton Radiation Damage Experiment on P-Channel CCD for an X-ray CCD camera onboard the Astro-H satellite
Koji Mori, Yusuke Nishioka, Satoshi Ohura +16
We report on a proton radiation damage experiment on P-channel CCD newly developed for an X-ray CCD camera onboard the Astro-H satellite. The device was exposed up to 10^9 protons…
Suzaku and XMM-Newton Observations of the Fornax cluster: Temperature and Metallicity Distribution
Hideyoshi Murakami, Madoka Komiyama, Kyoko Matsushita +7
Suzaku observed a central region and five offset regions within 0.2 r180 in the Fornax cluster, a nearby poor cluster, and XMM-Newton mapped the cluster with 15 pointings out to 0.…
Abundance Patterns in the Interstellar Medium of the S0 Galaxy NGC 1316 (Fornax A) Revealed with Suzaku
Saori Konami, Kyoko Matsushita, Ryo Nagino +3
The Suzaku X-ray satellite observed the nearby S0 galaxy NGC 1316, a merger remnant aged 3 Gyr. The total good exposure time was 48.7 ksec. The spectra were well represented by a t…
Mass Estimation of Merging Galaxy Clusters
Motokazu Takizawa, Ryo Nagino, Kyoko Matsushita
We investigate the impact of mergers on the mass estimation of galaxy clusters using -body + hydrodynamical simulation data. We estimate virial mass from these data and compare…
The Abundance Pattern of O, Ne, Mg, and Fe in the Interstellar Medium of S0 Galaxy NGC 4382 Observed with Suzaku
Ryo Nagino, Kyoko Matsushita
We derived O, Ne, and Mg abundances in the interstellar medium (ISM) of a relatively isolated S0 galaxy, NGC 4382, observed with the Suzaku XIS instruments and compared the O/Ne/Mg…
Gravitational potential and X-ray luminosities of early-type galaxies observed with XMM-Newton and Chandra
Ryo Nagino, Kyoko Matsushita
We study dark matter content in early-type galaxies and investigate whether X-ray luminosities of early-type galaxies are determined by the surrounding gravitational potential. We…
Suzaku observations of metallicity distribution in the intracluster medium of the NGC 5044 group
Madoka Komiyama, Kosuke Sato, Ryo Nagino +2
The metallicity distribution in the intracluster medium of the NGC 5044 group was studied up to 0.3 r_180 using the XIS instrument on board the Suzaku satellite. Abundances of O, M…
