Constraining Disk-to-Corona Power Transfer Fraction, Soft X-ray Excess Origin, and Black Hole Spin Population of Type-1 AGN across Mass Scales
Labani Mallick, Ciro Pinto, John Tomsick +6
Understanding the nature of the accretion disk, its interplay with the X-ray corona, and assessing black hole spin demographics remain open challenges in astrophysics. In this pape…
Non-stationary variability in accreting compact objects
William Alston
Accreting compact objects show variations in source flux over a broad range of timescales and in all wavebands. The light curves typically show a lognormal distribution of flux and…
The remarkable X-ray variability of IRAS 13224-3809 I: The variability process
W. N. Alston, A. C. Fabian, D. J. K. Buisson +17
We present a detailed X-ray timing analysis of the highly variable NLS1 galaxy, IRAS 13224-3809. The source was recently monitored for 1.5 Ms with XMM-Newton which, combined with 5…
False periodicities in quasar time-domain surveys
S. Vaughan, P. Uttley, A. G. Markowitz +5
There have recently been several reports of apparently periodic variations in the light curves of quasars, e.g. PG 1302-102 by Graham et al. (2015a). Any quasar showing periodic os…
