Remarkable Spectral Variability of PDS 456

Ehud Behar, Shai Kaspi, James Reeves +3

We report on the highest to date signal-to-noise-ratio X-ray spectrum of the luminous quasar PDS 456, as obtained during two XMM-Newton orbits in September 2007. The present spectr…

Cosmic Ray Spallation in Radio-Quiet Active Galactic Nuclei: A Case Study of NGC 4051

T. J. Turner, L. Miller

We investigate conditions for and consequences of spallation in radio-quiet Seyfert galaxies. The work is motivated by the recent discovery of significant line emission at 5.44 keV…

A correlation between the spectral and timing properties of AGN

I. E. Papadakis, M. Sobolewska, P. Arevalo +5

We present the results from a combined study of the average X-ray spectral and timing properties of 14 nearby AGN. For 11 of the sources in the sample, we used all the available da…

On the efficiency of production of the Fe Kalpha emission line in neutral matter

T. Yaqoob, K. D. Murphy, L. Miller +1

The absolute luminosity of the Fe Kalpha emission line from matter illuminated by X-rays in astrophysical sources is nontrivial to calculate except when the line-emitting medium is…

The absorption-dominated model for the X-ray spectra of type I active galaxies: MCG-6-30-15

L. Miller, T. J. Turner, J. N. Reeves

MCG-6-30-15 is the archetypal example of a type I active galaxy showing broad "red-wing" emission in its X-ray spectrum at energies below the 6.4 keV Fe K-alpha emission line and a…

A Compton-thick Wind in the High Luminosity Quasar, PDS 456

J. N. Reeves, P. T. O'Brien, V. Braito +7

PDS 456 is a nearby (z=0.184), luminous (L_bol ~10^47 erg/s) type I quasar. A deep 190 ks Suzaku observation in February 2007 revealed the complex, broad band X-ray spectrum of PDS…
