Discovery of soft and hard X-ray time lags in low-mass AGNs
Labani Mallick, Daniel R. Wilkins, William N. Alston +5
The scaling relations between the black hole (BH) mass and soft lag properties for both active galactic nuclei (AGNs) and BH X-ray binaries (BHXRBs) suggest the same underlying phy…
Returning radiation in strong gravity around black holes: Reverberation from the accretion disc
D. R. Wilkins, J. A. García, T. Dauser +1
We study reflected X-ray emission that returns to the accretion disc in the strong gravitational fields around black holes using General Relativistic ray tracing and radiative tran…
Evidence for an emerging disc wind and collimated outflow during an X-ray flare in the narrow-line Seyfert 1 galaxy Mrk 335
L. C. Gallo, A. G. Gonzalez, S. G. H. Waddell +13
A triggered 140 ks XMM-Newton observation of the narrow-line Seyfert 1 (NLS1) Mrk 335 in December 2015 caught the active galaxy at its lowest X-ray flux since 2007. The NLS1 is rel…
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…
On the illumination of neutron star accretion discs
D. R. Wilkins
The illumination of the accretion disc in a neutron star X-ray binary by X-rays emitted from (or close to) the neutron star surface is explored through general relativistic ray tra…
Towards modelling X-ray reverberation in AGN: Piecing together the extended corona
D. R. Wilkins, E. M. Cackett, A. C. Fabian +1
Models of X-ray reverberation from extended coronae are developed from general relativistic ray tracing simulations. Reverberation lags between correlated variability in the direct…
