Evidence of TeV halos around millisecond pulsars
Evidence of TeV halos around millisecond pulsars
Using data from the HAWC gamma-ray telescope, we have studied a sample of 37 millisecond pulsars (MSPs), selected for their spindown power and proximity. From among these MSP, we have identified four which favor the presence of very high-energy gamma-ray emission at a level of $(2\mathrm{\ensuremath{\Delta}}\mathrm{ln}\mathcal{L}{)}^{1/2}\ensuremath{\ge}2.5$. Adopting a correlation between …
