In Orbit Timing Calibration of the Hard X-Ray Detector on Board Suzaku
Yukikatsu Terada, Teruaki Enoto, Ryouhei Miyawaki +28
The hard X-ray detector (HXD) on board the X-ray satellite Suzaku is designed to have a good timing capability with a 61 s time resolution. In addition to detailed descriptions…
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…
Suzaku Detection of Extended/Diffuse Hard X-Ray Emission from the Galactic Center
Takayuki Yuasa, Ken-ichi Tamura, Kazuhiro Nakazawa +12
Five on-plane regions within +/- 0.8deg of the Galactic center were observed with the Hard X-ray Detector (HXD) and the X-ray Imaging Spectrometer (XIS) onboard Suzaku. From all re…
Spectral evolution of GRB 060904A observed with Swift and Suzaku -- Possibility of Inefficient Electron Acceleration
Daisuke Yonetoku, Sachiko Tanabe, Toshio Murakami +39
We observed an X-ray afterglow of GRB 060904A with the Swift and Suzaku satellites. We found rapid spectral softening during both the prompt tail phase and the decline phase of an…
Suzaku Observations of Hercules X-1 : Measurements of the Two Cyclotron Harmonics
Teruaki Enoto, Kazuo Makishima, Yukikatsu Terada +10
The accretion-powered pulsar Her X-1 was observed with Suzaku twice in its main-on state, on 2005 October 5-6 and 2006 March 29-30, for a net exposure of 30.5 ks and 34.4 ks, respe…
Measuring the Broad-band X-Ray Spectrum from 400 eV to 40 keV in the Southwest Part of the Supernova Remnant RX J1713.7-3946
Tadayuki Takahashi, Takaaki Tanaka, Yasunobu Uchiyama +13
We report on results from Suzaku broadband X-ray observations of the southwest part of the Galactic supernova remnant (SNR) RX J1713.7-3946 with an energy coverage of 0.4-40 keV. T…
The Suzaku Observation of the Nucleus of the Radio-Loud Active Galaxy Centaurus A: Constraints on Abundances of the Accreting Material
A. Markowitz, T. Takahashi, S. Watanabe +16
A Suzaku observation of the nucleus of the radio-loud AGN Centaurus A in 2005 has yielded a broadband spectrum spanning 0.3 to 250 keV. The net exposure times after screening were:…
X-Ray Study of Temperature and Abundance Profiles of the Cluster of Galaxies Abell 1060 with Suzaku
Kosuke Sato, Noriko Y. Yamasaki, Manabu Ishida +14
We carried out observations of the central and 20' east offset regions of the cluster of galaxies Abell 1060 with Suzaku. Spatially resolved X-ray spectral analysis has revealed te…
