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 afterglow of GW170817 from every angle: Prospects for detecting the afterglows of binary neutron star mergers
Brian James Morsony, Ryan De Los Santos, Rubin Hernandez +5
To date GW170817, produced by a binary neutron star (BNS) merger, is the only gravitational wave event with an electromagnetic (EM) counterpart. It was associated with a prompt sho…
Suppression of AGN-Driven Turbulence by Magnetic Fields in a Magnetohydrodynamic Model of the Intracluster Medium
Christopher J. Bambic, Brian J. Morsony, Christopher S. Reynolds
We investigate the role of AGN feedback in turbulent heating of galaxy clusters. Specifically, we analyze the production of turbulence by g-modes generated by the supersonic expans…
Late time afterglow observations reveal a collimated relativistic jet in the ejecta of the binary neutron star merger GW170817
Davide Lazzati, Rosalba Perna, Brian J. Morsony +5
The binary neutron star (BNS) merger GW170817 was the first astrophysical source detected in gravitational waves and multi-wavelength electromagnetic radiation. The almost simultan…
Off-axis prompt X-ray transients from the cocoon of short gamma-ray bursts
Davide Lazzati, Diego Lopez-Camara, Matteo Cantiello +3
We present the results of numerical simulations of the prompt emission of short-duration gamma-ray bursts. We consider emission from the relativistic jet, the mildly relativistic c…
Off-axis emission of short gamma-ray bursts and the detectability of electromagnetic counterparts of gravitational wave detected binary mergers
Davide Lazzati, Alex Deich, Brian J. Morsony +1
We present calculations of the wide angle emission of short-duration gamma-ray bursts from compact binary merger progenitors. Such events are expected to be localized by their grav…
