The 3HSP high energy blazars catalog |
|
Abstract |
Observations have shown that HSPs play a crucial role in TeV/very high energy astronomy, and we built an HSP catalog, 3HSP, contains ~2000 HSP candidates, based on multi-frequencies data to provide candidates for future TeV instruments. Given that the 3HSP is currently the largest and most complete HSP catalog, the statistical properties of 3HSP may represent the whole HSP population and may shed light on the long-standing loose of cosmological evolution of blazars. HSP catalog provides good candidates for the search of sources in VHE band. With a dedicated gamma-ray analysis using Fermi PASS 8 data at 3HSP sources position, there were 150 new gamma-ray detections found, called 1BIGB catalog. The most recent successful case is a new TeV source, PGC 2402248, was detected by the MAGIC collaboration, applying a 3HSP source as observation seed. A tool, VOU-Blazars, was developed to search blazar candidates effectively. The tool could point out all the possible VHE counterparts at the certain position in a relatively large region immediately and rule out bad and uncertain candidates. With VOU-Blazars, we will find more HSP candidates and figure out the counterpart for VHE sources in a more efficient way. |
