A catalog of gamma-ray source candidates from 16 years of Fermi-LAT data at |

Context. Sixteen years of continuous observations with the Fermi Large Area Telescope (LAT) provide an unprecedented opportunity to search for faint or previously unrecognized γ-ray emitters, particularly at high energies where the angular resolution improves and the diffuse background is reduced. Aims. We present a new catalog of γ-ray source candidates identified using a data-driven, clustering-based analysis of Pass 8 LAT data above 3 GeV at Galactic latitudes of |b| > 10°. Methods. 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. Results. We detect 3112 γ-ray cluster candidates, of which 2932 are associated with known γ-ray sources. Crossmatching yields 37 counterparts in 1CGH, 23 in CRATES, 21 in Roma-BZCAT, and 17 in MST-12yr. The remaining 370 clusters have no known γ-ray counterpart and are proposed as new source candidates.
