Description
Using LHAASO-KM2A (2021–2025) and LHAASO-WCDA (2021–2025) data, we detected a gamma-ray source, J2346+5145, with a test statistic (TS) of ~171.10 and a 2D Gaussian extension of ~0.14° . This source lies within the 95% positional uncertainty of 1LHAASO J2346+5138 (TS=47.6) from the First LHAASO Catalog. It is also spatially close to the intermittent extreme high-frequency-peaked BL Lac (EHBL) object 1ES 2344+514. We will present the temporal and spectral properties of J2346+5145 in the LHAASO-WCDA and LHAASO-KM2A bands, and further explore its nature by incorporating multi-wavelength data and different extragalactic background light absorption models.
