Description
We present a systematic analysis of pulsar TeV halos using data from the LHAASO. A sample of at least six halo sources has been studied with a unified analysis framework, including Geminga, Monogem, PSR J0622+3749, PSR J0631+1036, PSR J0248+6021, and PSR J0633+0632. For each source, we perform spatial and spectral modeling to constrain the diffusion properties of high-energy electrons and derive their energy spectra. This work represents an initial population-level study of TeV halos with LHAASO. Ongoing efforts aim to expand the source sample and improve the robustness of the measurements, ultimately enabling a deeper understanding of cosmic-ray propagation in the vicinity of pulsars.
