Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth
A. U. Abeysekara, A. Albert, R. Alfaro +113
The unexpectedly high flux of cosmic ray positrons detected at Earth may originate from nearby astrophysical sources, dark matter, or unknown processes of cosmic-ray secondary prod…
A Search for Dark Matter in the Galactic Halo with HAWC
A. U. Abeysekara, A. M. Albert, R. Alfaro +100
The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is a wide field-of-view observatory sensitive to 500 GeV - 100 TeV gamma rays and cosmic rays. With its observations…

Discovery of very-high-energy emission from RGB J2243+203 and derivation of its redshift upper limit
A. U. Abeysekara, S. Archambault, A. Archer +67
Very-high-energy (VHE; 100 GeV) gamma-ray emission from the blazar RGB J2243+203 was discovered with the VERITAS Cherenkov telescope array, during the period between 21 and 24…
VERITAS long term monitoring of Gamma-Ray emission from the BL Lacertae object
Anushka Udara Abeysekara
BL Lacertae is the prototype of the blazar subclass known as BL Lac type objects. BL Lacertae object itself is a low-frequency-peaked BL Lac(LBL). Very high energy (VHE) gamma ray…
