The XMM-Newton view of PG quasars: II. Properties of the Fe K-alpha line
E. Jimenez-Bailon, E. Piconcelli, M. Guainazzi +3
The properties of the fluorescence Fe K-alpha emission lines of a sample of 38 quasars (QSOs) observed with XMM-Newton are studied. These objects are included in the optically sele…
The variable XMM-Newton spectrum of Markarian 766
M. J. Page, K. O. Mason, F. J. Carrera +10
The narrow-line Seyfert 1 galaxy Markarian 766 was observed for 60 ks with the XMM-Newton observatory. The source shows a complex X-ray spectrum. The 2-10 keV spectrum can be adequ…
Multiwavelength observations of short time-scale variability in NGC 4151. IV. Analysis of multiwavelength continuum variability
R. A. Edelson et al
This paper combines data from the three preceding papers in order to analyze the multi-waveband variability and spectral energy distribution of the Seyfert~1 galaxy NGC~4151 during…
Multiwavelength observations of short time-scale variability in NGC 4151. I. Ultraviolet observations
D. M. Crenshaw et al
We present the results of an intensive ultraviolet monitoring campaign on the Seyfert 1 galaxy NGC 4151, as part of an effort to study its short time-scale variability over a broad…
