Legacy analysis of Milky Way dwarf spheroidal satellite galaxies: an update

A. Circiello, M. Di Mauro, M. Ajello +3

Studies of Fermi-Large Area Telescope (LAT) data coincident with dwarf spheroidal satellite galaxies (dSphs) of the Milky Way (MW) have put the most stringent constraints on models…

The gamma-ray emission from Radio Galaxies and their contribution to the Isotropic Gamma-Ray Background

A. Circiello, A. McDaniel, M. Di Mauro +6

We evaluate the contribution to the Isotropic Gamma-Ray Background (IGRB) coming from Radio Galaxies (RGs), the subclass of radio-loud Active Galactic Nuclei (AGN) with the highest…

Einstein@Home Searches for Gamma-ray Pulsars in the Inner Galaxy

C. J. Clark, M. Di Mauro, J. Wu +14

The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center, which can potentially be explained by unresolve…

Multiwavelength observation of a candidate pulsar halo LHAASO J0621+3755 and the first X-ray detection of PSR J0622+3749

C. B. Adams, A. Archer, P. Bangale +71

Pulsar halos are regions around middle-aged pulsars extending out to tens of parsecs. The large extent of the halos and well-defined central cosmic-ray accelerators make this new c…

Evaluating the Potential to Constrain Dark Matter Annihilation with Fermi-LAT Observations of Ultra-Faint Compact Stellar Systems

A. Circiello, A. McDaniel, A. Drlica-Wagner +4

Recent results from numerical simulations and models of galaxy formation suggest that recently discovered ultra-faint compact stellar systems (UFCSs) in the halo of the Milky Way (…
