英文摘要The LHAASO J2018+3651 region is one of the brightest sources in the sky at TeV energies. Photons with energies up to 0.27 PeV from this region have been detected with the Large High Altitude Air Shower Observatory (LHAASO) and here we present a detailed study of this region using more data from LHAASO. This analysis resolves the region into six sources: LHAASO J2018+3641, LHAASO J2019+3649, LHAASO J2021+3657, LHAASO J2016+3712, LHAASO J2013+3610 and LHAASO J2028+3655. An investigation of the morphology and spectrum for LHAASO J2018+3641, LHAASO J2019+3649 and LHAASO J2021+3657 are the focus and we find that the spectrum above TeV deviates significantly from a single power-law, and is best described by a power-law with exponential cutoff. The three sources may be associated with PSR J2021+3651 and its X-ray pulsar wind nebula. Additionally, LHAASO J2016+3712 is tentatively associated with the evolved supernova remnant CTB 87. © Copyright owned by the author(s)
