X-ray variability analysis of a large series of XMM-Newton + NuSTAR observations of NGC 3227

A. P. Lobban, T. J. Turner, J. N. Reeves +2

We present a series of X-ray variability results from a long XMM-Newton + NuSTAR campaign on the bright, variable AGN NGC 3227. We present an analysis of the lightcurves, showing t…

The third data release of the Kilo-Degree Survey and associated data products

J. T. A. de Jong, G. A. Verdoes Kleijn, T. Erben +40

The Kilo-Degree Survey (KiDS) is an ongoing optical wide-field imaging survey with the OmegaCAM camera at the VLT Survey Telescope. It aims to image 1500 square degrees in four fil…

The Global Implications of the Hard X-ray Excess in Type 1 AGN

M. M. Tatum, T. J. Turner, L. Miller +1

Recent evidence for a strong 'hard excess' of flux at energies > 20 keV in some Suzaku observations of type 1 Active Galactic Nuclei (AGN) has motivated an exploratory study of the…

Modeling the Fe K Line Profiles in Type I AGN with a Compton-Thick Disk Wind

M. M. Tatum, T. J. Turner, S. A. Sim +4

We have modeled a small sample of Seyfert galaxies that were previously identified as having simple X-ray spectra with little intrinsic absorption. The sources in this sample all c…

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…
