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…

Constraints on Spin-Dependent Dark Matter Scattering with Long-Lived Mediators from TeV Observations of the Sun with HAWC

A. Albert, R. Alfaro, C. Alvarez +91

We analyze the Sun as a source for the indirect detection of dark matter through a search for gamma rays from the solar disk. Capture of dark matter by elastic interactions with th…

First HAWC Observations of the Sun Constrain Steady TeV Gamma-Ray Emission

A. Albert, R. Alfaro, C. Alvarez +92

Steady gamma-ray emission up to at least 200 GeV has been detected from the solar disk in the Fermi-LAT data, with the brightest, hardest emission occurring during solar minimum. T…

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…
