Low frequency X-ray timing with Gaussian processes and reverberation in the radio-loud AGN 3C 120
D. R. Wilkins
A framework is developed to perform Fourier-domain timing analysis on X-ray light curves with gaps, employing Gaussian processes to model the probability distribution underlying th…
Characterisation of the Particle-Induced Background of XMM-Newton EPIC-pn: Short and Long Term Variability
Esra Bulbul, Ralph Kraft, Paul Nulsen +16
The particle-induced background of X-ray observatories is produced by Galactic Cosmic Ray (GCR) primary protons, electrons, and He ions. Events due to direct interaction with the d…
The XMM-Newton/HST view of the obscuring outflow in the Seyfert Galaxy Mrk 335 observed at extremely low X-ray flux
Anna Lia Longinotti, Gerard Kriss, Yair Krongold +8
The Seyfert Galaxy Mrk 335 is known for its frequent changes of flux and spectral shape in the X-ray band occurred during recent years. These variations may be explained by the ons…
Supermassive Black Hole Spin and Reverberation
A. Zoghbi, D. R. Wilkins, L. Brenneman +7
X-ray reverberation mapping has emerged as a powerful probe of microparsec scales around AGN, and with high sensitivity detectors, its full potential in echo-mapping the otherwise…
Black hole magnetosphere with small scale flux tubes--II. Stability and dynamics
Yajie Yuan, Anatoly Spitkovsky, Roger D. Blandford +1
In some Seyfert Galaxies, the hard X-rays that produce fluorescent emission lines are thought to be generated in a hot corona that is compact and located at only a few gravitationa…
