Implications from Late-Time X-ray Detections of Optically Selected Tidal Disruption Events: State Changes, Unification, and Detection Rates
P. G. Jonker, N. C. Stone, A. Generozov +2
We present Chandra X-ray observations of four optically-selected tidal disruption events (TDEs) obtained 4-9 years after discovery. Three sources were detected with luminosities be…
An Overabundance of Black Hole X-Ray Binaries in the Galactic Center from Tidal Captures
A. Generozov, N. C. Stone, B. D. Metzger +1
A large population of X-ray binaries (XRBs) was recently discovered within the central parsec of the Galaxy by Hailey et al. While the presence of compact objects on this scale due…
The influence of circumnuclear environment on the radio emission from TDE jets
A. Generozov, P. Mimica, B. D. Metzger +3
Dozens of stellar tidal disruption events (TDEs) have been identified at optical, UV and X-ray wavelengths. A small fraction of these, most notably Swift J1644+57, produce radio sy…
Circumnuclear Media of Quiescent Supermassive Black Holes
Aleksey Generozov, Nicholas C. Stone, Brian D. Metzger
We calculate steady-state, one-dimensional hydrodynamic profiles of hot gas in slowly accreting ("quiescent") galactic nuclei for a range of central black hole masses …
Lyman edges in supermassive black hole binaries
Aleksey Generozov, Zoltan Haiman
We propose a new spectral signature for supermassive black hole binaries (SMBHBs) with circumbinary gas disks: a sharp drop in flux blueward of the Lyman limit. A prominent edge is…
Physical Properties of the Inner Shocks in Hot, Tilted Black Hole Accretion Flows
Aleksey Generozov, Omer Blaes, P. Chris Fragile +1
Simulations of hot, pressure supported, tilted black hole accretion flows, in which the angular momentum of the flow is misaligned with the black hole spin axis, can exhibit two no…
