Comptonization by Reconnection Plasmoids in Black Hole Coronae I: Magnetically Dominated Pair Plasma
Navin Sridhar, Lorenzo Sironi, Andrei M. Beloborodov
We perform two-dimensional particle-in-cell simulations of reconnection in magnetically dominated electron-positron plasmas subject to strong Compton cooling. We vary the magnetiza…
Periodic Fast Radio Bursts from Luminous X-ray Binaries
Navin Sridhar, Brian D. Metzger, Paz Beniamini +4
The discovery of periodicity in the arrival times of the fast radio bursts (FRBs) poses a challenge to the oft-studied magnetar scenarios. However, models that postulate that FRBs…
Reflection Modeling of the Black Hole Binary 4U~163047: the Disk Density and Returning Radiation
Riley Connors, Javier García, John Tomsick +11
We present the analysis of X-ray observations of the black hole binary 4U~163047 using relativistic reflection spectroscopy. We use archival data from the RXTE, Swift, and NuSTA…
Shock-powered radio precursors of neutron star mergers from accelerating relativistic binary winds
Navin Sridhar, Jonathan Zrake, Brian D. Metzger +2
During the final stages of a compact object merger, if at least one of the binary components is a magnetized neutron star (NS), then its orbital motion substantially expands the NS…
Implications of a "Fast Radio Burst" from a Galactic Magnetar
Ben Margalit, Paz Beniamini, Navin Sridhar +1
A luminous radio burst was recently detected in temporal coincidence with a hard X-ray flare from the Galactic magnetar SGR 1935+2154 with a time and frequency structure consistent…
Evidence for Returning Disk Radiation in the Black Hole X-ray Binary XTE J1550-564
Riley M. T. Connors, Javier A. Garcia, Thomas Dauser +7
We explore the accretion properties of the black hole X-ray binary \j1550\ during its outbursts in 1998/99 and 2000. We model the disk, corona, and reflection components of X-ray s…
