Identifying potentially missed extended sources in the Fermi-LAT 4FGL Catalog using clustering analysis
Giovanni Cozzolongo, Alison M. W. Mitchell, Samuel T. Spencer +2
Many Fermi Large Area Telescope (LAT) sources remain unassociated. Some may be extended sources represented by multiple catalog entries, as found for HESS J1813-178. We search for…
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…
Towards probabilistic multiclass classification of gamma-ray sources
Dmitry Malyshev, Aakash Bhat
Machine learning algorithms have been used to determine probabilistic classifications of unassociated sources. Often classification into two large classes, such as Galactic and ext…
Machine learning methods for constructing probabilistic Fermi-LAT catalogs
Aakash Bhat, Dmitry Malyshev
Classification of sources is one of the most important tasks in astronomy. Sources detected in one wavelength band, for example using gamma rays, may have several possible associat…
Fermi Bubbles: an Elephant in the Gamma-ray Sky
Dmitry Malyshev
The Fermi bubbles are one of the most remarkable features in the gamma-ray sky revealed by the Fermi Large Area Telescope (LAT). The nature of the gamma-ray emission and the origin…
Spectral components analysis of diffuse emission processes
Dmitry Malyshev
We develop a novel method to separate the components of a diffuse emission process based on an association with the energy spectra. Most of the existing methods use some informatio…
