Millisecond pulsars, TeV halos, and implications for the Galactic Center gamma-ray excess

Millisecond pulsars, TeV halos, and implications for the Galactic Center gamma-ray excess

Observations by HAWC indicate that many young pulsars (including Geminga and Monogem) are surrounded by spatially extended, multi-TeV emitting regions. It is not currently known, however, whether TeV emission is also produced by recycled, millisecond pulsars (MSPs). In this study, we perform a stacked analysis of 24 MSPs within HAWC's …
