The Suzaku view of highly-ionised outflows in AGN: II -- Location, energetics and scalings with Bolometric Luminosity
J. Gofford, J. N. Reeves, D. E. McLaughlin +4
Ongoing studies with XMM-Newton have shown that powerful accretion disc winds, as revealed through highly-ionised Fe\,K-shell absorption at E>=6.7 keV, are present in a significant…
The Spectral Energy Distribution and Emission-Line properties of the NLS1 Galaxy Arakelian 564
P. Romano, S. Mathur, T. J. Turner +11
We present the intrinsic spectral energy distribution (SED) of the NLS1 Arakelian 564, constructed with contemporaneous data obtained during a multi-wavelength, multi-satellite obs…
The Properties and the Evolution of the Highly Ionized Gas in MR2251-178
S. Kaspi, H. Netzer, D. Chelouche +3
We present the first XMM-Newton observations of the radio-quiet quasar MR2251-178. We model the X-ray spectrum with two power laws, one at high energies with a slope of Γ=1.6 and t…
Variable UV Absorption in the Seyfert 1.5 Galaxy NGC 3516: The Case for Associated UV and X-ray Absorption
S. B. Kraemer, D. M. Crenshaw, I. M. George +3
We present observations of the UV absorption lines in the Seyfert 1 galaxy NGC 3516, obtained at a resolution of / 40,000 with the Space Telescope Imaging Spectrog…
A 12-day ASCA Observation of the Narrow-Line Seyfert 1 Galaxy Ton S180: Time-Selected Spectroscopy
P. Romano, T. J. Turner, S. Mathur +1
We present an analysis of the X-ray variability properties of the NLS1 galaxy Ton S180, based upon a 12-day continuous ASCA observation. We observe flux variations of a factor of 3…
On the dependence of the iron K-line profiles with luminosity in Active Galactic Nuclei
K. Nandra, I. M. George, R. F. Mushotzky +2
We present evidence for changes in the strength and profile of the iron K-alpha line in Active Galactic Nuclei (AGN), based on X-ray observations with ASCA. There is a clear decrea…
