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…
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…
A soft X-ray reverberation lag in the AGN ESO 113-G010
E. M. Cackett, A. C. Fabian, A. Zoghbi +3
Reverberation lags have recently been discovered in a handful of nearby, variable AGN. Here, we analyze a ~100 ksec archival XMM-Newton observation of the highly variable AGN, ESO…
