Asteroid Occultations with VERITAS: Observations and Considerations

Joshua Bartkoske, Anne Duerr, Dave Kieda

Occultations, the covering up of one celestial body by another celestial body, have been used in astronomy for millennia to learn about the sun and moon. Since 2018, VERITAS has im…

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…

Constraints on Axion-Like Particles from VERITAS Observations of a Flaring Radio Galaxy in the Perseus Cluster

C. B. Adams, A. Archer, P. Bangale +62

Background: Axion-like particles (ALPs) are hypothetical particles that emerge in numerous theoretical extensions to the Standard Model. Their coupling to electromagnetic field imp…

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…

VERITAS and multiwavelength observations of the Blazar B3 2247+381 in response to an IceCube neutrino alert

Atreya Acharyya, Colin B. Adams, Priyadarshini Bangale +494

While the sources of the diffuse astrophysical neutrino flux detected by the IceCube Neutrino Observatory are still largely unknown, one of the promising methods used towards under…

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…
