BL Lac candidates for TeV observations
Listed in IVOA Registry (Virtual Observatory)
BL Lac objects are the most numerous class of extragalactic TeV-detected sources.
Description
One of the biggest difficulties in investigating their TeV emission is due to their limited number, since only 47 BL Lac objects are known to be TeV emitters. In this paper, we propose new criteria to select TeV BL Lac candidates based on infrared and X-ray observations.
We apply our selection criteria to the BL Lac objects listed in the ROMA-BZCAT catalog (Cat. J/A+A/495/691), thereby identifying 41 potential TeV emitters. We then perform a search over a more extended sample combining the ROSAT bright source catalog (Cat.

IX/10) and the WISE all-sky survey (Cat. II/311), revealing 54 additional candidates for TeV observations. Our investigation also led to a tentative classification of 16 unidentified X-ray sources as BL Lac candidates.
This analysis provides new interesting BL Lac targets for future observations with ground-based Cherenkov telescopes.
