Identifying charged particle background events in X-ray imaging detectors with novel machine learning algorithms
D. R. Wilkins, S. W. Allen, E. D. Miller +8
Space-based X-ray detectors are subject to significant fluxes of charged particles in orbit, notably energetic cosmic ray protons, contributing a significant background. We develop…
Lifting the curtain: The Seyfert galaxy Mrk 335 emerges from deep low-state in a sequence of rapid flare events
S. Komossa, D. Grupe, L. C. Gallo +7
The narrow-line Seyfert 1 galaxy Mrk 335 was one of the X-ray brightest AGN, but it has systematically faded since 2007. Here, we report the discovery with Swift of a sequence of b…
Characterising continuum variability in the radio-loud narrow-line Seyfert 1 galaxy IRAS 17020+4544
A. G. Gonzalez, L. C. Gallo, P. Kosec +4
We present results of temporal and spectral analyses on four XMM-Newton EPIC pn observations of IRAS 17020+4544, a narrow-line Seyfert 1 galaxy with evidence of a radio jet. Analys…
Venturing beyond the ISCO: Detecting X-ray emission from the plunging regions around black holes
D. R. Wilkins, C. S. Reynolds, A. C. Fabian
We explore how X-ray reverberation around black holes may reveal the presence of the innermost stable circular orbit (ISCO), predicted by General Relativity, and probe the dynamics…
The Soft State of the Black Hole Transient Source MAXI J1820+070: Emission from the Edge of the Plunge Region?
A. C. Fabian, D. J Buisson, P. Kosec +18
The Galactic black hole X-ray binary MAXI J1820+070 had a bright outburst in 2018 when it became the second brightest X-ray source in the Sky. It was too bright for X-ray CCD instr…
Blueshifted absorption lines from X-ray reflection in IRAS 13224-3809
A. C. Fabian, C. S. Reynolds, J. Jiang +17
We explore a disc origin for the highly-blueshifted, variable absorption lines seen in the X-ray spectrum of the Narrow Line Seyfert 1 galaxy IRAS13224-3809. The blueshift correspo…
A dynamic black hole corona in an active galaxy through X-ray reverberation mapping
William N. Alston, Andrew C. Fabian, Erin Kara +18
X-ray reverberation echoes are assumed to be produced in the strongly distorted spacetime around accreting supermassive black holes. This signal allows us to spatially map the geom…
