Assessing black hole spin in deep Suzaku observations of Seyfert 1 AGN
A. R. Patrick, J. N. Reeves, A. P. Lobban +2
We present a broad-band analysis of deep Suzaku observations of nearby Seyfert 1 AGN: Fairall 9, MCG--6-30-15, NGC 3516, NGC 3783 and NGC 4051. The use of deep observations (exposu…
Study of LINER sources with broad H(alpha) emission. X-ray properties and comparision to luminous AGN and X-ray binaries
G. Younes, D. Porquet, B. Sabra +1
We study the X-ray properties of LINER sources with definite detection of a broad H(alpha) emission line in their optical spectra, LINER 1s from Ho et al. sample. These objects pre…
Fe Ka line emission from the Arches cluster region - evidence for ongoing particle bombardment?
R. Capelli, R. S. Warwick, D. Porquet +2
We present the results of eight years of XMM-Newton observations of the region surrounding the Arches cluster in the Galactic Center. We study the spatial distribution and temporal…
A broad-band X-ray view of the Warm Absorber in radio-quiet quasar MR2251-178
J. Gofford, J. N. Reeves, T. J. Turner +6
We present the analysis of a new broad-band X-ray spectrum (0.6-180.0 keV) of the radio-quiet quasar MR 2251-178 which uses data obtained with both Suzaku and the Swift/BAT. In acc…
He-like ions as practical astrophysical plasma diagnostics: From stellar coronae to active galactic nuclei
Delphine Porquet, Jacques Dubau, Nicolas Grosso
We review X-ray plasma diagnostics based on the line ratios of He-like ions. Triplet/singlet line intensities can be used to determine electronic temperature and density, and were…
