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…
The Photospheric Emission of a Short-Duration Gamma-Ray Burst Emerging from a Realistic Binary Neutron Star Merger
Nathan Walker, Davide Lazzati, Tyler Parsotan +1
The almost simultaneous detection of GRB170817A and GW170817 ushered in nearly a decade of interest in binary neutron star mergers and their multi-messenger signals, resulting in a…
The Role of a Neutron Component in the Photospheric Emission of Long-Duration Gamma-Ray Burst Jets
Nathan Walker, Tyler Parsotan, Davide Lazzati
Long-duration gamma-ray bursts (LGRBs), thought to be produced during core-collapse supernovae, may have a prominent neutron component in the outflow material. If present, neutrons…
GRB 191019A: a short gamma-ray burst in disguise from the disk of an active galactic nucleus
Davide Lazzati, Rosalba Perna, Benjamin Gompertz +1
Long and short gamma-ray bursts (GRBs), canonically separated at around 2 seconds duration, are associated with different progenitors: the collapse of a massive star and the merger…
Dynamics of a relativistic jet through magnetized media
Leonardo Garcia-Garcia, Diego Lopez-Camara, Davide Lazzati
The merger of two neutron stars (NSs) produces the emission of gravitational waves, the formation of a compact object surrounded by a dense and magnetized environment, and the laun…
The effects of Time-Variable Absorption due to Gamma-Ray Bursts In Active Galactic Nuclei Accretion Disks
Michael Ray, Davide Lazzati, Rosalba Perna
Both long and short gamma-ray bursts (GRBs) are expected to occur in the dense environments of active galactic nuclei (AGN) accretion disks. As these bursts propagate through the d…
