Quasi-periodic eruption spectral-timing: EMRIs crossing warped accretion disks
Joheen Chakraborty, Andrew Mummery, Eliot Quataert +3
Quasi-periodic eruptions (QPEs) are repeating X-ray transients from galactic nuclei potentially caused by a stellar-mass orbiter repeatedly colliding with the accretion disk of a s…
HLX-1 as a Repeating Partial Tidal Disruption Event around an Intermediate-Mass Black Hole
Fangyuan Yu, Andrew Mummery, Muryel Guolo
ESO 24349 HLX--1 is one of the first known compelling intermediate-mass black hole (IMBH) candidates, but the origin of its recurrent X-ray outbursts remains unsettled. In this…
Observational signatures of warped accretion flows in tidal disruption events
Andrew Mummery, Eliot Quataert
We analyze the possible observational signatures and evolution of global warps in the accretion flows produced in tidal disruption events. These warps are driven by Lense-Thirring…
The chirping of Lense-Thirring precession in tidal disruption event accretion flows
Andrew Mummery, Eliot Quataert
Tidal disruption event X-ray light curves do not appear to show clear signs of periodic modulation. This is naively somewhat surprising since the stars that are disrupted originate…
The plunging region of thin accretion discs across the black hole spin range
Jake Rule, Andrew Mummery, Steven Balbus +2
We compute and test analytic models for the plunging region dynamics, thermodynamics, and magnetic fields against dedicated 3D global general relativistic magnetohydrodynamics (MHD…
One year of broadband radio monitoring of the enigmatic transient GRB 250702B reveals the evolution of the relativistic jet
A. J. Goodwin, James C. A. Miller-Jones, Itai Sfaradi +18
We present an extensive radio monitoring campaign of the unique extragalactic transient GRB 250702B, with observations spanning 0.65-233 GHz from 6-356 d (observer frame) post-disc…
