High Galactic latitude Fermi sources of γ-rays with energies above 100 GeV.

Abstract (from CDS):

We present a catalog of sources of very high energy (E>100GeV) γ-rays detected by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope at Galactic latitudes |b|≥10°. We cross-correlate the directions of individual photons with energies above 100GeV detected by Fermi/LAT with the first year Fermi catalog of sources detected at lower energies. We find a significant correlation between the arrival directions of the highest energy photons and positions of Fermi sources, with the possibility of chance coincidences at the level of 10–45. We present a list of Fermi sources contributing to the correlation signal. A similar analysis is performed to cross-correlate the catalog of BL Lac objects with the highest energy photons detected by Fermi. We produce a catalog of high Galactic latitude Fermi sources visible at 100-300GeV energies. The catalog is divided into two parts. The first part contains a list of 50 higher significance sources among which there can be three possible false detections. The second part of the catalog contains a list of 25 lower significance sources, among which six are possibly false detections. Finally we identify eight additional sources from the cross-correlation analysis with the BL Lac catalog. The reported sources of E>100GeV γ-rays span a broad range of redshifts, up to z∼1. Most of the sources are BL Lac type objects. Only 17 out of 83 objects in our list were previously reported as VHE γ-ray sources.
