Cross-match between Swift-BAT & Fermi-LAT 10yrs
Listed in IVOA Registry (Virtual Observatory)
We report the results of a cross-match study between the hard X-ray and GeV gamma-ray catalogs, by making use of the latest 105 month Swift-Burst Alert Telescope (BAT) and 10yr Fermi-Large Area Telescope (LAT) catalogs, respectively.
Description
The spatial cross-matching between the two catalogs results in the matching of 132 point-like sources, including 5% of false-match sources. Additionally, 24 sources that have been identified as the same identifications are matched.
Among the 75 extended sources in the Fermi-LAT catalog, 31 sources have spatial coincidences with at least one Swift-BAT source inside their extent. All the matched sources consist of blazars (>60%), pulsars and pulsar wind nebulae (13%), radio galaxies (7%), binaries (5%), and others. Compared to the original catalogs, the matched sources are characterized by a double-peaked photon index distribution, higher flux, and larger gamma-ray variability index.

This difference arises from the different populations of sources, particularly the large proportion of blazars (i.e., flat-spectrum radio quasar and BL Lac). We also report 13 cross-matched and unidentified sources. The matched sources in this study would be promising in the intermediate energy band between the hard X-ray and GeV gamma-ray observations, that is the unexplored MeV gamma-ray domain.
