Suzaku observations of iron lines and reflection in AGN
Kataoka, J.; Fabian, A. C.; Takahashi, T. +8 more
Initial results on the iron K-shell line and reflection component in several AGN observed as part of the Suzaku Guaranteed Time program are reviewed. This paper discusses a small sample of Compton-thin Seyferts observed to date with Suzaku; namely MCG -5-23-16, MCG -6-30-15, NGC 4051, NGC 3516, NGC 2110, 3C 120 and NGC 2992. The broad iron K\alpha…
A short introduction to broad and variable iron lines around black holes
Fabian, A. C.
Accreting black holes often show iron line emission in their X-ray spectra. When this line emission is very broad or variable then it is likely to originate from close to the black hole. The theory and observations of such broad and variable iron lines are briefly reviewed here. In order for a clear broad line to be found, one or more of the follo…
Suzaku observation of NGC 3516: complex absorption and the broad and narrow Fe K lines
Miniutti, G.; Reeves, J. N.; Yaqoob, T. +9 more
We present preliminary results from a 150 ks Suzaku observation of the Seyfert 1 galaxy NGC 3516. Suzaku's wide bandpass has enabled us to deconvolve the broadband emitting and absorbing components in this object, breaking model degeneracies inherent in previous, smaller-bandpass spectra. The primary power-law continuum is absorbed by an ionized a…
The broad iron line physics: summary and outlook
Tanaka, Y.
A brief overview of the ESAC/XMM-Newton Science Operations Centre Workshop on ``Variable and Broad Iron Lines around Black Holes" is presented. Following the relativistic disk-line theory of accreting black holes, ASCA discovered such broad iron lines from several AGN. XMM-Newton and Chandra confirmed the ASCA results, but also found more complexi…
The Japanese X-ray missions
Fujita, Y.
Here, I briefly introduce Japanese X-ray missions: Suzaku and NeXT. Suzaku was launched on July 10, 2005. NeXT will be launched in 2011. They will open new windows into the workings of black holes, clusters of galaxies, active galaxies, and other very energetic objects.
