Naoki Isobe, Kazuo Makishima, Hiromitsu Takahashi +8
Suzaku observation of an ultraluminous X-ray source, NGC 2403 Source 3, performed on 2006 March 16--17, is reported. The Suzaku XIS spectrum of Source 3 was described with a multi-…
Suzaku Observations of M82 X-1 : Detection of a Curved Hard X-ray Spectrum
Ryohei Miyawaki, Kazuo Makishima, Shinya Yamada +5
A report is presented on Suzaku observations of the ultra-luminous X-ray source X-1 in the starburst galaxy M82, made three time in 2005 October for an exposure of ~ 30 ks each. Th…
Suzaku Results on Cygnus X-1 in the Low/Hard State
Kazuo Makishima, Hiromitsu Takahashi, Shin'ya Yamada +9
The black-hole binary Cygnus X-1 was observed for 17 ks with the Suzaku X-ray observatory in 2005 October, while it was in a low/hard state with a 0.7-300 keV luminosity of 4.6 x 1…
