Gamma rays from the quasar PKS 1441+25: story of an escape
A. U. Abeysekara, S. Archambault, A. Archer +103
Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the Universe. The det…
Science Highlights from VERITAS
D. Staszak, A. U. Abeysekara, S. Archambault +88
The Very Energetic Radiation Imaging Telescope Array System (VERITAS) is a ground-based array located at the Fred Lawrence Whipple Observatory in southern Arizona and is one of the…
Search for TeV Gamma-Ray Emission from Point-like Sources in the Inner Galactic Plane with a Partial Configuration of the HAWC Observatory
A. U. Abeysekara, R. Alfaro, C. Alvarez +95
A survey of the inner Galaxy region of Galactic longitude l in [+15, +50] degree and latitude b in [-4,+4] degree is performed using one-third of the High Altitude Water Cherenkov…
VERITAS Discovery of Very High-Energy Gamma-Ray Emission from RGB J2243+203
A. U. Abeysekara
RGB J2243+203 is a blazar at an estimated redshift of greater than 0.39 that has been classified both as an intermediate-frequency-peaked BL Lac object and as a high-frequency-peak…

Experimental Constraints on γ-ray Pulsar Gap Models and the Pulsar GeV to Pulsar Wind Nebula TeV Connection
A. U. Abeysekara, J. T. Linnemann
The pulsar emission mechanism in the gamma-ray energy band is poorly understood. Currently, there are several models under discussion in the pulsar community. These models can be c…
