Prompt Searches for Very-High-Energy γ-Ray Counterparts to IceCube Astrophysical Neutrino Alerts
J. Abhir, A. Biland, K. Brand +817
The search for sources of high-energy astrophysical neutrinos can be significantly advanced through a multi-messenger approach, which seeks to detect the gamma rays that accompany…
Probing a cosmogenic origin of astrophysical neutrinos and cosmic rays using gamma-ray observations of TXS 0506+056
A. Acharyya, A. Archer, P. Bangale +58
In September 2017, a high-energy neutrino event detected by the IceCube Neutrino Observatory (IceCube-170922A) was associated, at the level, with a gamma-ray flare from the bl…
Multi-wavelength Study of HESS J0632+057: New Insights into Pulsar-Disk Interaction
Jaegeun Park, Hongjun An, Chanho Kim +60
We present an analysis of new multi-wavelength observations of the TeV gamma-ray binary HESS J0632+057, conducted using SALT, Swift, NuSTAR, and VERITAS in 2023--2024. By combining…
Measurement of the photosphere oblateness of Cassiopeiae via Stellar Intensity Interferometry with the VERITAS Observatory
A. Archer, J. P. Aufdenberg, P. Bangale +58
We use the stellar intensity interferometry system implemented with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) at Fred Lawrence Whipple Observatory (FLWO…
Multiwavelength observation of a candidate pulsar halo LHAASO J0621+3755 and the first X-ray detection of PSR J0622+3749
C. B. Adams, A. Archer, P. Bangale +71
Pulsar halos are regions around middle-aged pulsars extending out to tens of parsecs. The large extent of the halos and well-defined central cosmic-ray accelerators make this new c…
Constraints on the X-ray and Very High Energy -ray Flux from Supernova Remnant W44
A. Archer, P. Bangale, J. T. Bartkoske +55
Observations of GeV gamma-ray emission from the well-studied mixed-morphology supernova remnant (SNR) W44 by Fermi-LAT and AGILE imply that it is a site of significant cosmic ray a…
An in-depth study of Gamma rays from the Starburst Galaxy M 82 with VERITAS
Atreya Acharyya, Colin B. Adams, Priyadarshini Bangale +60
Assuming Galactic cosmic rays originate in supernovae and the winds of massive stars, starburst galaxies should produce very-high-energy (VHE; E100 GeV) gamma-ray emission via t…
