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-…
A rapid change in X-ray variability and a jet ejection in the black hole transient MAXI J1820+070
Jeroen Homan, Joe Bright, Sara E. Motta +13
We present Neutron Star Interior Composition Explorer X-ray and Arcminute Microkelvin Imager Large Array radio observations of a rapid hard-to-soft state transition in the black ho…
The X-ray Polarization Probe mission concept
Keith Jahoda, Henric Krawczynski, Fabian Kislat +100
The X-ray Polarization Probe (XPP) is a second generation X-ray polarimeter following up on the Imaging X-ray Polarimetry Explorer (IXPE). The XPP will offer true broadband polarim…
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…
Evidence for rapid disk formation and reprocessing in the X-ray bright tidal disruption event AT 2018fyk
T. Wevers, D. R. Pasham, S. van Velzen +15
We present optical spectroscopic and Swift UVOT/XRT observations of the X-ray and UV/optical bright tidal disruption event (TDE) AT 2018fyk/ASASSN-18ul discovered by ASAS-SN. The S…
Target of Opportunity Observations of Gravitational Wave Events with LSST
R. Margutti, P. Cowperthwaite, Z. Doctor +79
The discovery of the electromagnetic counterparts to the binary neutron star merger GW170817 has opened the era of GW+EM multi-messenger astronomy. Exploiting this breakthrough req…
