Constraining the local pulsar population with the cosmic-ray positron fraction

Constraining the local pulsar population with the cosmic-ray positron fraction

Abstract Observations of the TeV halos associated with nearby pulsars indicate that these objects inject significant fluxes of very high-energy electron-positrons pairs into the interstellar medium (ISM), thereby likely providing the dominant contribution to the cosmic-ray positron flux. In this paper, we use the cosmic-ray positron fraction as measured by …
