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…
Discovery of Diffuse X-ray Emission in One of the Nearest Massive Star-Forming Regions NGC 2024
Yuichiro Ezoe, Motohide Kokubun, Kazuo Makishima +2
A deep 75 ks {\it Chandra} ACIS--I data of NGC 2024 was analyzed, aiming at a search for diffuse X-ray emission in this one of the most nearby (415 pc) massive star-forming regions…
Long-term X-ray variability of quasars in the Lockman Hole field observed with ROSAT
Yu-ichiro Ezoe, Naoko Iyomoto, Kazuo Makishima +1
An improved method is utilized to estimate the X-ray power spectral densities (PSD) and the variation time scales of three quasars in the Lockman Hole field. Five archival ROSAT PS…
Study of the Long-Term X-Ray Variability of a Possible Quasar RX J0957.9+6903 with ASCA
Yu-ichiro Ezoe, Naoko Iyomoto, Kazuo Makishima
Long-term variability and spectral properties of a possible quasar, RX J0957.9+6903, were studied, utilizing 16 ASCA observations spanning 5.5 years. The average 0.7--10 keV spectr…
