Origin of X-ray Spectral Variation and the Seemingly Broad Iron-Line Spectral Feature in Seyfert Galaxies
Autor: Ebisawa, Ken; Iso, Naoki; Miyakawa, Takehiro; Inoue, Hajime
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present systematic X-ray data analysis of the Seyfert galaxies observed by Suzaku to study origin of their hard X-ray (2 - 40 keV) variations. In particular, we examine if the "Variable Partial Covering (VPC) model" ... -
X-Ray and Near-Infrared Spectroscopy of Dim X-Ray Point Sources Constituting the Galactic Ridge X-Ray Emission
Autor: Morihana, Kumiko; Tsujimoto, Masahiro; Ebisawa, Ken
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present the results of X-ray and Near-Infrared observations of the Galactic Ridge X-ray Emission (GRXE). We extracted 2,002 X-ray point sources in the Chandra Bulge Field (l =0°.113, b = 1°.424) down to ~10-14.8 ergscm-2s-1 ...
