The ASTRO-H X-ray Observatory
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +220
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…
Prospect of Studying Hard X- and Gamma-Rays from Type Ia Supernovae
K. Maeda, Y. Terada, D. Kasen +9
We perform multi-dimensional, time-dependent radiation transfer simulations for hard X-ray and gamma-ray emissions, following radioactive decays of 56Ni and 56Co, for two-dimension…
Recombining Plasma and Hard X-ray Filament in the Mixed-Morphology Supernova Remnant W44
Hiroyuki Uchida, Katsuji Koyama, Hiroya Yamaguchi +6
We report new features of the typical mixed-morphology (MM) supernova remnant (SNR) W44. In the X-ray spectra obtained with Suzaku, radiative recombination continua (RRCs) of highl…
A Suzaku Study of Ejecta Structure and Origin of Hard X-ray Emission in the Supernova Remnant G156.2+5.7
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +3
We report an X-ray study of the evolved Galactic supernova remnant (SNR) G156.2+5.7 based on six pointing observations with Suzaku. The remnant's large extent (100$\arcmin$ in diam…
Suzaku View of the Supernova Remnant RCW 86: X-Ray Studies of Newly-Discovered Fe-Rich Ejecta
Hiroya Yamaguchi, Katsuji Koyama, Hiroyuki Uchida
We report on results of imaging and spectral analysis of the supernova remnant (SNR) RCW 86 observed with Suzaku. The SNR is known to exhibit K-shell emission of low ionized Fe, po…
New Insights into SNR Evolution Revealed by the Discovery of Recombining Plasmas
Hiroya Yamaguchi, Midori Ozawa, Takao Ohnishi
We report the discovery of recombining plasmas in three supernova remnants (SNRs) with the Suzaku X-ray astronomy satellite. During SNR's evolution, the expanding supernova ejecta…
