Periastron Observations of TeV Gamma-Ray Emission from a Binary System with a 50-year Period

The VERITAS Collaboration, A. U. Abeysekara, W. Benbow +212

We report on observations of the pulsar / Be star binary system PSR J2032+4127 / MT91 213 in the energy range between 100 GeV and 20 TeV with the VERITAS and MAGIC imaging atmosphe…

VERITAS and Fermi-LAT observations of new HAWC sources

VERITAS Collaboration, A. U. Abeysekara, A. Archer +280

The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…

Measurement of Cosmic-ray Electrons at TeV Energies by VERITAS

VERITAS Collaboration, A. Archer, W. Benbow +58

Cosmic-ray electrons and positrons (CREs) at GeV-TeV energies are a unique probe of our local Galactic neighborhood. CREs lose energy rapidly via synchrotron radiation and inverse-…

Multiwavelength observations of the blazar BL Lacertae: a new fast TeV gamma-ray flare

A. U. Abeysekara, W. Benbow, R. Bird +74

Combined with very-long-baseline interferometry measurements, the observations of fast TeV gamma-ray flares probe the structure and emission mechanism of blazar jets. However, only…
