abstract

Recent observations have shown that pulsars are surrounded by extended regions which emit TeV-scale gamma rays through the inverse Compton scattering of very high energy electrons and positrons. Such TeV halos are responsible for a large fraction of the Milky Way's TeV-scale gamma-ray emission. In this paper, we calculate the gamma-ray spectrum from the population of TeV halos located within the Andromeda Galaxy, predicting a signal that is expected to be detectable by the Cherenkov Telescope Array (CTA). We also calculate the contribution from TeV halos to the isotropic gamma-ray background (IGRB), finding that these sources should contribute significantly to this flux at the highest measured energies, constituting up to $\sim 20\%$ of the signal observed above $\sim 0.1 \, {\rm TeV}$.

  1. GeV-TeV Connections in Galaxies: Evolutionary Signatures from Pulsars in Globular Clusters

    astro-ph.HE 2025-08 unverdicted novelty 5.0

    Globular cluster pulsar winds may make a significant contribution to GeV and TeV gamma-ray emission from massive quiescent galaxies, with strength tied to each galaxy's evolutionary history.
