Catalog of gamma-ray source candidates
Listed in IVOA Registry (Virtual Observatory)
Sixteen years of continuous observations with the Fermi Large Area Telescope (LAT) provide an unprecedented opportunity to search for faint or previously unrecognized gamma-ray emitters, particularly at high energies where the angular resolution improves and the diffuse background is reduced.
Description
We present a new catalog of gamma-ray source candidates identified using a data-driven, clustering-based analysis of Pass 8 LAT data above 3GeV at Galactic latitudes |b|>10{deg}.
The pipeline integrates the SIeving MEthod for FInding Core, version 3 (SIMEFIC III) for photon denoising with the density-based spatial clustering of applications with noise (DBSCAN) algorithm. We detect 3112 gamma-ray cluster candidates, of which 2932 are associated with known gamma-ray sources. Cross-matching yields 37 counterparts in 1CGH, 23 in CRATES, 21 in Roma-BZCAT, 17 in MST-12yr.

The remaining 370 clusters have no known gamma-ray counterpart and are proposed as new source candidates.
