Exploring the nature of Galactic unassociated sources detected by the Fermi-LAT

F. Acero, A. Acharyya, A. Adelfio +120

We investigate the nature of the unassociated sources detected by the Fermi-LAT close (|b|<10°) to the Galactic plane, representing 16% of all sources in the 4FGL-DR4 catalog. The…

Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

LAT Collaboration, S. Abdollahi, L. Baldini +586

Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…

Puzzling Variation of Gamma Rays from the Sun over the Solar Cycle Revealed with Fermi-LAT

A. Acharyya, A. Adelfio, M. Ajello +100

The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and…

Fermi detection of gamma-ray Emission from the Hot Coronae of Radio-quiet Active Galactic Nuclei

Jun-Rong Liu, Jian-Min Wang, Fermi-LAT Collaboration

Relativistic jets around supermassive black holes (SMBHs) are well-known powerful -ray emitters. In absence of the jets in radio-quiet active galactic nuclei (AGNs), how the SMB…

Periodic Gamma-ray Modulation of the blazar PG 1553+113 Confirmed by Fermi-LAT and Multi-wavelength Observations

S. Abdollahi, L. Baldini, G. Barbiellini +98

A 2.1-year periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in almost 7 year of data from the Fermi Large Area Tele…

Search for Extended GeV Sources in the Inner Galactic Plane

S. Abdollahi, F. Acero, A. Acharyya +108

The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
