Iron Emission Lines on the Galactic Ridge Observed with Suzaku
Shigeo Yamauchi, Ken Ebisawa, Yasuo Tanaka +5
In order to elucidate origin of the Galactic Ridge X-ray Emission, we analyzed Suzaku data taken at various regions along the Galactic plane and studied their Fe-K emission line fe…
Suzaku observations of the hard X-ray variability of MCG-6-30-15: the effects of strong gravity around a Kerr black hole
Giovanni Miniutti, Andrew C. Fabian, Naohisa Anabuki +21
Suzaku has, for the first time, enabled the hard X-ray variability of the Seyfert 1 galaxy MCG-6-30-15 to be measured. The variability in the 14-45 keV band, which is dominated by…
Partial Covering Interpretation of the X-Ray Spectrum of the NLS1 1H 0707-495
Yasuo Tanaka, Thomas Boller, Luigi Gallo +2
The X-ray spectrum of 1H 0707-495 obtained with XMM-Newton showing a deep flux drop at ~7 keV (Boller et al. 2002) is studied based on the partial covering concept. The previously…
A Complete Relativistic Ionized Accretion Disc in Cygnus X-1
A. J. Young, A. C. Fabian, R. R. Ross +1
The galactic black hole candidate Cygnus X-1 is observed to be in one of two X-ray spectral states; either the low/hard (low soft X-ray flux and a flat power law tail) or high/soft…
RXTE observation of NGC 6240: a search for the obscured active nucleus
Yasushi Ikebe, Karen Leighly, Yasuo Tanaka +3
The wide-band energy spectrum of NGC6240 over the range 0.5-200keV is investigated using the RXTE and ASCA data. The RXTE data provide the spectrum beyond the ASCA range (0.5-10 ke…
Erratum: ASCA Observations of the Absorption-Line Features from the Super-Luminal Jet Source GRS 1915+105
Taro Kotani, Ken Ebisawa, Tadayasu Dotani +4
We have discovered errors in the calculation of some of the Einstein coefficients in Table 5 and some plots in Figure 3. Due to the errors, the square-root section of the curves of…
