Hard X-ray Detector (HXD) on Board Suzaku
T. Takahashi, K. Abe, M. Endo +66
The Hard X-ray Detector (HXD) on board Suzaku covers a wide energy range from 10 keV to 600 keV by combination of silicon PIN diodes and GSO scintillators. The HXD is designed to a…
Detailed spectral study of an ultra-luminous compact X-ray source M81 X-9 in the disk dominated state
Naoko Tsunoda, Aya Kubota, Masaaki Namiki +3
We report on the results of detailed spectral studies of the ultra-luminous X-ray source (ULX), M81 X-9 (Holmberg IX X-1), made with XMM-Newton on 2001 April 22 and with ASCA on 19…
Spectral Evolution of a Luminous Compact X-Ray Source in NGC 253 with Chandra and XMM-Newton
Takaaki Tanaka, Masahiko Sugiho, Aya Kubota +2
Spectral studies of a luminous X-ray source, NGC 253 X21, are presented based on archival Chandra and XMM-Newton data. The Chandra observation on 1999 December 16 detected the sour…
The Apparent Host Galaxy of PKS 1413+135: HST, ASCA and VLBA Observations
Eric S. Perlman, John T. Stocke, Chris L. Carilli +5
PKS 1413+135 (z=0.24671) is one of very few radio-loud AGN with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to heavy abs…
Observations of the BL Lacertae Object OJ 287 in 1997 April and Nov ember
Naoki Isobe, Makoto Tashiro, Masahiko Sugiho +1
X-ray properties of the BL Lacertae object OJ 287, observed with ASCA on 1997 April 26 and November 17, are reported. The 0.5 -- 10 keV flux was lower than those obtained in previo…
