Signatures of Compact Object Mergers Inside Stars in AGN Disks
Matteo Cantiello, Alexander J. Dittmann, Saavik Ford +4
Disks of gas accreting onto supermassive black holes, powering active galactic nuclei (AGN), can capture stars from nuclear star clusters or form stars in situ via gravitational in…
Explaining the X-ray Precursor, Ultra-long Prompt Emission, and Week-long Decay of GRB250702B with a Jetted Micro-TDE
Fulya Kıroğlu, Taeho Ryu, Alexander Tchekhovskoy +3
The longest detected gamma-ray burst, GRB250702B, exhibited seven hours of prompt -ray emission, preceded by a soft X-ray precursor ( day earlier) and followed by a weeks…
The TDE Population from First-Principles Models of Stellar Disruption and Debris Dynamics
Tsvi Piran, Julian Krolik, Taeho Ryu
We present a physically-grounded population model for optical tidal disruption events (TDEs) that combines first-principles hydrodynamic simulations of stellar disruption with stat…
Pulsational Instability of Quasi-Stars: Interpreting the Variability of Little Red Dots
Matteo Cantiello, Jake B. Hassan, Rosalba Perna +5
The JWST discovery of "Little Red Dots" (LRDs) has revealed a population of compact, red sources at that likely host supermassive black holes (SMBHs). Recent observat…
Hydrodynamic Simulations of Tidal Disruption Encores
Ian P. A. Johnson, Taeho Ryu, Rosalba Perna
We present hydrodynamic simulations with the moving-mesh code AREPO of Tidal Disruption Encores (TDEEs) in nuclear star clusters (NSCs). TDEEs arise when a stellar-mass black hole…
Delayed emission from luminous blue optical transients in black-hole binary systems
Davide Lazzati, Rosalba Perna, Taeho Ryu +1
At least three members of the recently identified class of fast luminous blue optical transient show evidence of late-time electromagnetic activity in great excess of what predicte…
