Absence of TeV halos around millisecond pulsars

A. U. Abeysekara, R. Alfaro, C. Alvarez +82

TeV halos are extended very-high-energy (VHE; 0.1-100 TeV) gamma-ray emission around middle-aged pulsars. So far they have only been found around isolated pulsars, but it has been…

Search for Decaying Dark Matter in the Virgo Cluster of Galaxies with HAWC

A. Albert, R. Alfaro, J. C. Arteaga-Velázquez +55

The decay or annihilation of dark matter particles may produce a steady flux of very-high-energy gamma rays detectable above the diffuse background. Nearby clusters of galaxies pro…

Evidence that Ultra-High-Energy Gamma Rays are a Universal Feature Near Powerful Pulsars

HAWC Collaboration, A. Albert, R. Alfaro +97

The highest-energy known gamma-ray sources are all located within 0.5 degrees of extremely powerful pulsars. This raises the question of whether ultra-high-energy (UHE; 56 TeV)…
