Bayesian Evidence for Inspiraling Hotspot Motion in the Galactic Center
Pablo Ruales, Maciek Wielgus, Delilah E. A. Gates +1
During flaring episodes, polarimetric observations of the Galactic Center black hole Sagittarius A* (Sgr A*) reveal evolving, loop-like trajectories in the Stokes Q-U plane, the so…
Photon Ring Astrometry I: A Simple Spin Measurement Technique for High-Resolution Images of M87*
Delilah E. A. Gates, Dominic O. Chang, Aaron Held +1
The supermassive black hole M87* is a target for future horizon-scale imaging that will resolve the first lensed () sub-image of the photon ring. In this work, we iden…
Polarization Signatures of Inspiraling Hotspots around Kerr Black Holes
Pablo Ruales, Delilah E. A. Gates, Alejandro Cárdenas-Avendaño
Polarimetric interferometry is a powerful tool for probing both black hole accretion physics and the background spacetime. Current models aimed at explaining the observed multiwave…
Black Holes with Accretion Disks as High-Energy Particle Colliders
Delilah E. A. Gates
In principle, rapidly rotating black holes (BHs) with accretion disks -- either prograde or retrograde -- could naturally act as high-energy particle colliders (HEPCs) because part…
Morphology of Relativistically Broadened Line Emission from Axisymmetric Equatorial Accretion Disks
Delilah E. A. Gates, Chau Truong, Amrita Sahu +1
Single-frequency emission from an accretion disk around a black hole is broadened into a line profile due to gravitational redshift and the motion of the disk's particles relative…
Near-Horizon Collisions around Near-Extremal Black Holes
Delilah E. A. Gates
Black holes have sometimes been described as astrophysical particle accelerators because finite energy particles can collide near the horizon with divergent center-of-mass (CM) ene…
Signatures of particle collisions near extreme black holes
Delilah E. A. Gates, Shahar Hadar
Finite-energy particles in free fall can collide with diverging center-of-mass energy near rapidly rotating black holes. What are the most salient observational signatures of this…
