Search for TeV emission from unassociated excesses in the 3HWC catalog
ORAL
Abstract
There are 65 significant detections in the third catalog of TeV gamma-ray sources from the High Altitude Water Cherenkov (HAWC) observatory (3HWC). Among many interesting objects, the 3HWC catalog contains twenty sources that are more than 1 degree away from any previously detected TeV source. These are called either orphan or unassociated TeV sources. With three more years of HAWC data than presented in the 3HWC catalog, we followed up on these twenty objects in time and also searched for lower energy correlations. We will present the candidate sources, their spectra, and the temporal evolution of the excess significance compared to the expectation for steady sources.
