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…
ASTRO-H White Paper - Plasma Diagnostic and Dynamics of the Galactic Center Region
K. Koyama, J. Kataoka, M. Nobukawa +16
The most characteristic high-energy phenomena in the Galactic center (GC) region is the presence of strong K-shell emission lines from highly ionized Si, S, Ar, Ca, Fe and Ni, whic…
Discovery of Recombining Plasma in the Supernova Remnant 3C 391
Tamotsu Sato, Katsuji Koyama, Tadayuki Takahashi +2
Recent X-ray study of middle-aged supernova remnants (SNRs) reveals strong radiative recombination continua (RRCs) associated with overionized plasmas, of which the origin still re…
X-ray Filament with a Strong 6.7 keV Line in the Galactic Center Region
Shigeo Yamauchi, Miku Shimizu, Shinya Nakashima +3
An elongated X-ray source with a strong K-shell line from He-like iron (Fe XXVI) is found at (RA, Dec)_{J2000.0}=(17h44m00s.0, -29D13'40''.9) in the Galactic center region. The pos…
Development and Performance of Kyoto's X-ray Astronomical SOI pixel (SOIPIX) sensor
Takeshi G. Tsuru, Hideaki Matsumura, Ayaki Takeda +18
We have been developing monolithic active pixel sensors, known as Kyoto's X-ray SOIPIXs, based on the CMOS SOI (silicon-on-insulator) technology for next-generation X-ray astronomy…
Abundances in the Ejecta of Core Collapse Supernova Remnants, G350.1-0.3 and G349.7+0.2
Masato Yasumi, Masayoshi Nobukawa, Shinya Nakashima +5
We present Suzaku results of the two Galactic supernova remnants (SNRs), G350.1-0.3 and G349.7+0.2. We find Al and Ni K alpha lines from both the SNRs for the first time, in additi…
