Soft Gamma-ray Detector for the ASTRO-H Mission
Hiroyasu Tajima, Roger Blandford, Teruaki Enoto +26
ASTRO-H is the next generation JAXA X-ray satellite, intended to carry instruments with broad energy coverage and exquisite energy resolution. The Soft Gamma-ray Detector (SGD) is…
The ASTRO-H Mission
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +174
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
Metallicity of the Fossil Group NGC 1550 Observed with Suzaku
Kosuke Sato, Madoka Kawaharada, Kazuhiro Nakazawa +4
We studied the temperature and metal abundance distributions of the intra-cluster medium (ICM) in a group of galaxies NGC 1550 observed with Suzaku. The NGC 1550 is classified as a…
Broad-band study with Suzaku of the magnetar class
Teruaki Enoto, Kazuhiro Nakazawa, Kazuo Makishima +3
Broad-band (0.8-70 keV) spectra of the persistent X-ray emission from 9 magnetars were obtained with Suzaku, including 3 objects in apparent outburst. The soft X-ray component was…
White dwarf masses in intermediate polars observed with the Suzaku satellite
Takayuki Yuasa, Kazuhiro Nakazawa, Kazuo Makishima +5
Context. White dwarfs (WDs) in cataclysmic variables (CVs) are important experimental laboratories where the electron degeneracy is taking place on a macroscopic scale. Magnetic CV…
XMM-Newton Observation of the Northwest Radio Relic Region in Abell 3667
A. Finoguenov, C. L. Sarazin, K. Nakazawa +2
Abell 3667 is the archetype of a merging cluster with radio relics. The NW radio relic is the brightest cluster relic or halo known, and is believed to be due to a strong merger sh…
