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…
Gamma-ray signature of superluminous supernovae: Fermi-LAT GeV detection of SN 2017egm and evidence of a central engine
F. Acero, A. Acharyya, A. Adelfio +116
Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10-100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms po…
Temporal evolution of the periodic GeV signal from 4FGL J1913.2+0512 and analysis of the SS 433 / W50 lobes
Ãmer Faruk Ãoban, Diego F. Torres, Jian Li +3
SS 433 is a microquasar whose relativistic jets precess every ~162 days, providing a laboratory for jet-interstellar medium interactions. We present a comprehensive analysis of 16…
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…
Gamma-ray Pulsar Emission is Mostly Stable on Timescales from Minutes to Years
Matthew Kerr
We present a method for the detection and characterization of random changes in the flux from -ray pulsars on sub-hour timescales, much shorter than variations that can be acce…
