Description

Using observational data from the LHAASO and the Fermi-LAT, we conduct a systematic investigation of the sky region harboring the TeV gamma-ray source LHAASO J2005+3415. This source displays a notably extended spatial morphology and a relatively soft energy spectrum in the TeV band; its GeV counterpart, however, exhibits spatial and morphological consistency with the TeV emission, indicating a common physical origin for the multi-band gamma-ray radiation. Additionally, we report the discovery of two new gamma-ray sources in the southeastern portion of the LHAASO J2005+3415 field, with statistical significances of approximately 13.9σ and 7.5σ, respectively.
