TMT: Runtime Backdoor Detection for Vision-Language-Action Policies on Unseen Tasks
Zirun Zhou, Jingfeng Zhang, HaoChuan Xu +4
Backdoored vision-language-action (VLA) policies can preserve benign task performance while producing malicious actions when a trigger appears. Detecting such activation is difficu…
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…
McFACTS. IV. Electromagnetic Counterparts to AGN-disk-embedded Binary Black Hole Mergers
Emily McPike, Rosalba Perna, K. E. Saavik Ford +10
The accretion disks of active galactic nuclei (AGNs) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GWs…
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…
The Growth of the Central Black Holes in Quasi-stars
Jake Hassan, Rosalba Perna, Matteo Cantiello +3
Observations by JWST have confirmed the presence of supermassive black holes (BHs) at redshifts , lending support to scenarios in which BHs experience rapid growth thro…
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…
