摘　　要：Extra-galactic gammaray sources,such as gamma-ray bursts,active galactic nuclei,starburst galaxies,are interesting and important targets for LHAASO observations.In this chapter,the prospects of detecting these sources with LHAASO and their physical implications are studied.The upgrade plan for the Water Cherenkov Detector Array(WCDA),which aims to enhance the detectability of relatively lower energy photons,is also presented.In addition,a study on constraining the extragalactic background light with LHAASO observation of blazars is presented.
