Search for TeV emission from unbiased survey of high-frequency-peaked BL Lacs*

More than 50 high frequency peaked BL Lacs (HBLs) have been detected by ground-based TeV gamma-ray observatories, making them the dominant population of extragalactic sources at TeV energies. Between 2019 and 2022, the VERITAS observatory has conducted a campaign to observe a flux-limited sample of 36 X-ray selected HBLs in order to produce the first unbiased survey of TeV emission from HBL blazars. The VERITAS HBL sample includes 21 known TeV sources as well as 15 blazars which do not yet have reported TeV emission. These observations have the goal to find unbiased estimates of the TeV flux of HBLs, which are generally only reported from their flaring states, and also to detect new TeV blazars which have not previously been observed. First results from this survey will be presented, as well as their implications for understanding the intrinsic properties of HBL sources.
