2023年高能所博士后学术交流会

Abstract: We report the first catalog of TeV gamma-ray sources realized with the most sensitive wide field-of-view TeV telescope ever built. Since January 2020, it continuously surveys the northern sky with field of view ∼ 2 sr and >90% duty cycle. Using 508 days of data collected by full array of LHAASO-WCDA and 933 days of data collected by LHAASO-KM2A, 90 sources were detected significantly, including 5 extra-galactic sources. 32 of these sources have no known TeV counterparts within 0.5 degree. In this talk, detailed analysis will be presented including background estimation, searching strategy and summary of the catalog.
