The First LHAASO Catalog of Gamma-Ray Sources

Abstract

We present the first catalog of very-high energy and ultra-high energy gamma-ray sources detected by the Large High Altitude Air Shower Observatory (LHAASO). The catalog was compiled using 508 days of data collected by the Water Cherenkov Detector Array (WCDA) from March 2021 to September 2022 and 933 days of data recorded by the Kilometer Squared Array (KM2A) from January 2020 to September 2022. This catalog represents the main result from the most sensitive large coverage gamma-ray survey of the sky above 1 TeV, covering declination from $-$20${}^{\circ }$ to 80${}^{\circ }$. In total, the catalog contains 90 sources with an extended size smaller than $2^{\circ }$ and a significance of detection at $>5\sigma$. Based on our source association criteria, 32 new TeV sources are proposed in this study. Among the 90 sources, 43 sources are detected with ultra-high energy ($E>100$ TeV) emission at $>4\sigma$ significance level. We provide the position, extension, and spectral characteristics of all the sources in this catalog.
