Test for Echo: X-ray Reflection Variability in the Seyfert-2 AGN NGC 4388
B. Gediman, J. M. Miller, A. Zoghbi +4
We report on a study of the narrow Fe K line and reflection spectrum in the well-known Seyfert-2 AGN, NGC 4388. X-ray spectra summed from two extensive NICER monitoring campaign…
The High Energy X-ray Probe (HEX-P): Probing Accretion onto Stellar Mass Black Holes
Riley Connors, John Tomsick, Paul Draghis +20
Accretion is a universal astrophysical process that plays a key role in cosmic history, from the epoch of reionization to galaxy and stellar formation and evolution. Accreting stel…
Evidence of a Massive Stellar Disruption in the X-ray Spectrum of ASASSN-14li
J. M. Miller, B. Mockler, E. Ramirez-Ruiz +7
The proximity and duration of the tidal disruption event (TDE) ASASSN-14li led to the discovery of narrow, blue-shifted absorption lines in X-rays and UV. The gas seen in X-ray abs…
An Extreme Black Hole in the Recurrent X-ray Transient XTE J2012+381
Paul A. Draghis, Jon M. Miller, McKinley C. Brumback +3
The black hole candidate XTE J2012+381 underwent an outburst at the end of 2022. We analyzed 105 NICER observations and 2 NuSTAR observations of the source during the outburst. The…
The Spin of a Newborn Black Hole: Swift J1728.9-3613
Paul A. Draghis, Mayura Balakrishnan, Jon M. Miller +7
The origin and distribution of stellar-mass black hole spins are a rare window into the progenitor stars and supernova events that create them. Swift J1728.9-3613 is an X-ray binar…
The Black Hole Candidate Swift J1728.93613 and the Supernova Remnant G351.90.9
Mayura Balakrishnan, Paul A. Draghis, Jon M. Miller +12
A number of neutron stars have been observed within the remnants of the core-collapse supernova explosions that created them. In contrast, black holes are not yet clearly associate…
