Spectral transitions of an ultraluminous X-ray source, NGC 2403 Source 3
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-…
Hard X-Ray Spectrum from West Lobe of Radio Galaxy Fornax A Observed with Suzaku
Makoto S. Tashiro, Naoki Isobe, Hiromi Seta +2
An observation of the West lobe of radio galaxy Fornax A (NGC 1316) with Suzaku is reported. Since Feigelson et al. (1995) and Kaneda et al. (1995) discovered the cosmic microwave…
The estimate of kinetic powers of jets in FRII radio galaxies: existence of invisible components?
H. Ito, M. Kino, N. Kawakatu +2
We investigate the total kinetic powers (L_j) and ages (t_age) of powerful jets in FR II radio galaxies by comparison of the dynamical model of expanding cocoons with observations.…
Constraint of Non-thermal X-ray Emission from the On-going Merger Cluster Abell 3376 with Suzaku
Naomi Kawano, Yasushi Fukazawa, Sho Nishino +10
Clusters of galaxies are among the best candidates for particle acceleration sources in the universe, a signature of which is non-thermal hard X-ray emission from the accelerated r…
Suzaku Observation of HCG 62: Temperature, Abundance, and Extended Hard X-ray Emission Profiles
Kazuyo Tokoi, Kosuke Sato, Yoshitaka Ishisaki +14
We present results of 120 ks observation of a compact group of galaxies HCG~62 () with Suzaku XIS and HXD-PIN\@. The XIS spectra for four annular regions were fitted with…
Discovery of a bright transient ultraluminous X-ray source Suzaku J1305-4931 in NGC 4945
Naoki Isobe, Aya Kubota, Kazuo Makishima +5
This paper reports the discovery of a bright X-ray transient source, Suzaku J1305-4913, in the south-west arm of the nearby Seyfert II galaxy NGC 4945. It was detected at a 0.5 --…
