The destruction and recreation of the X-ray corona in a changing-look Active Galactic Nucleus

C. Ricci, E. Kara, M. Loewenstein +16

We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-…

Probing the Cosmological Evolution of Super-massive Black Holes using Tidal Disruption Flares

Dheeraj R. Pasham, Dacheng Lin, Richard Saxton +5

The question of how supermassive black holes (SMBHs) grow over cosmic time is a major puzzle in high-energy astrophysics. One promising approach to this problem is via the study of…
