An XMM-Newton view of the X-ray flat radio-quiet quasar PG 1416-129
D. Porquet, J. N. Reeves, A. Markowitz +3
(abridged) The radio-quiet quasar PG1416-129 (z=0.129) exhibits atypical optical and X-ray properties. Between 1990 and 2000, in response to its optical continuum decrease, the ``c…
The variable X-ray spectrum of Markarian 766 - I. Principal components analysis
L. Miller, T. J. Turner, J. N. Reeves +3
Aims: We analyse a long XMM-Newton spectrum of the narrow-line Seyfert 1 galaxy Mrk 766, using the marked spectral variability on timescales >20ks to separate components in the X-r…
The Energy-dependent X-ray Timing Characteristics of the Narrow Line Seyfert 1 Mkn 766
A. Markowitz, I. E. Papadakis, P. Arevalo +3
We present the energy-dependent power spectral density (PSD) and cross-spectral properties of Mkn 766, obtained from combining data obtained during an XMM-Newton observation spanni…
An XMM-Newton survey of broad iron lines in AGN
K. Nandra, P. M. O'Neill, I. M. George +2
We report on the iron K-alpha line properties of a sample of Seyfert galaxies observed with the XMM-Newton EPIC pn instrument. Using a systematic and uniform analysis, we find that…
Simultaneous Ultraviolet and X-ray Observations of the Seyfert Galaxy NGC 4151. II. Physical Conditions in the UV Absorbers
S. B. Kraemer, D. M. Crenshaw, J. R. Gabel +8
We present a detailed analysis of the intrinsic absorption in the Seyfert 1 galaxy NGC 4151 using UV spectra from the HST/STIS and FUSE, obtained 2002 May as part of a set of conte…
