cds-question@unistra.frgamma-ray-astronomysurveysWe present the first catalog of very-high-energy and ultra-high-energy gamma-ray sources detected by the Large High Altitude Air Shower Observatory. The catalog was compiled using 508 days of data collected by the Water Cherenkov Detector Array from 2021 March to 2022 September and 933 days of data recorded by the Kilometer Squared Array from 2020 January to 2022 September. This catalog represents the main result from the most sensitive large coverage gamma-ray survey of the sky above 1TeV, covering decl. from -20{deg} to 80{deg}. In total, the catalog contains 90 sources with an extended size smaller than 2{deg} 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>100TeV) emission at >4{sigma} significance level. We provide the position, extension, and spectral characteristics of all the sources in this catalog.2024ApJS..271...25Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/271/25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/psr : ATNF Pulsar Catalogue (Manchester+, 2005)IX/67 : Incremental Fermi LAT 4th source cat.
