Identifying potentially missed extended sources in the Fermi-LAT 4FGL Catalog using clustering analysis
Giovanni Cozzolongo, Alison M. W. Mitchell, Samuel T. Spencer +2
Context. Since its launch in 2008, the Fermi Large Area Telescope (LAT) has detected thousands of sources, many of which remain unassociated. Some may be extended sources represent…
Clustering analysis of Fermi-LAT unidentified point sources
Giovanni Cozzolongo, Alison M. W. Mitchell, Samuel T. Spencer +2
The Fermi Large Area Telescope (LAT) has detected thousands of sources since its launch in 2008, with many remaining unidentified. Some of these point sources may arise from source…
Classification of Fermi-LAT unassociated sources with machine learning in the presence of dataset shifts
Dmitry V. Malyshev
About one third of Fermi Large Area Telescope (LAT) sources are unassociated. We perform multi-class classification of Fermi-LAT sources using machine learning with the goal of pro…
Galactic center GeV excess and classification of Fermi-LAT sources with machine learning
Dmitry V. Malyshev
Excess of gamma rays with a spherical morphology around the Galactic center (GC) observed in the Fermi large area telescope (LAT) data is one of the most intriguing features in the…
