Description

Following our previous work on optimizing the analysis of LHAASO-KM2A full-array data at large zenith angles, we present preliminary results from a search for gamma-ray sources in the inner Galaxy, focusing on the W28, W30, and Galactic Center regions. These regions host various gamma-ray emission components, primarily associated with pulsar wind nebulae and interactions between high-energy cosmic rays and molecular clouds. We report several promising gamma-ray source candidates and present preliminary investigations of their spatial distributions and spectral properties. These results demonstrate the potential of large-zenith-angle observations with LHAASO-KM2A for studying particle acceleration and gamma-ray emission in the inner Galaxy.
