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…
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…
Calcium Triplet Absorption is Common around Little Red Dots
Jenny E. Greene, Hanpu Liu, Raphael E. Hviding +29
We present new evidence for an optically thick atmosphere surrounding Little Red Dots (LRDs) in the form of Ca absorption at rest-frame 8500A, the calcium triplet (CaT). Building o…
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…
Little Red Dots As Super-Eddington Fountain Flows
Nicholas Kaaz, Eliot Quataert, Taya Govreen-Segal +1
Little red dots (LRDs) may be powered by supermassive black holes (SMBHs) accreting above the Eddington limit. Spectroscopy of LRDs often shows absorption troughs blueshifted by $\…
Constraining Tidal Migration with the Hot Jupiter Population
Linhao Ma, Yubo Su, Samuel W. Yee +3
Hot Jupiters with orbital periods shorter than a few days have probably been affected by tidal orbital migration. We develop an analytical framework for constraining tidal migratio…
