We report the identification of a new ultra-high-energy (UHE) $\gamma$-ray source, designated LHAASO1907+0913, through a detailed analysis of LHAASO survey data. The source is clearly detected by both the WCDA and KM2A detectors with statistical significances of $8.8 \sigma$ and $5.5 \sigma$, respectively. The best-fit source position is determined to be R.A. = $286.85^\circ \pm 0.03^\circ $,...
The ultrahigh-energy gamma-ray source LHAASO J1912+1013, designated 1LHAASO J1912+1014u in the first LHAASO catalog and detected by H.E.S.S. as HESS J1912+101, lies near the middle-aged pulsar PSR J1913+1011 and is an important target for studying Galactic cosmic-ray acceleration and propagation. We analyze LHAASO observations from 2021 March 5 to 2025 July 31 and Fermi--LAT data from 2008...
