Identification of a Large-Scale Diffuse Gamma-Ray Structure in the Southern Galactic Hemisphere
Zhen Xie, Xiaoyuan Huang, Bing Liu +1
We identify and characterize a large-scale diffuse gamma-ray structure in the Southern Galactic Hemisphere using 17 yr of Fermi-LAT data. An energy-dependent likelihood analysis, i…
Astrophysical origins of TeV features in the cosmic-ray lepton spectrum
Zhen Xie, Ruizhi Yang
Precise measurements of high-energy cosmic-ray electrons and positrons have revealed spectral structures that are difficult to capture with a single smooth power-law background. Th…
Enhancing the Angular Resolution of Large Array of imaging atmospheric Cherenkov Telescope (LACT) at Ultra-High Energies
Zhipeng Zhang, Ruizhi Yang, Shoushan Zhang +5
The Large Array of Imaging Atmospheric Cherenkov Telescopes (LACT) is dedicated to high-resolution morphological studies of PeVatrons. In this work, we present a fundamental invest…
Prospects for Observing the Microquasar SS 433 with the LACT Array
Zhen Xie, Zhipeng Zhang, Ruizhi Yang
We investigate the observational capabilities of the upcoming LACT Cherenkov telescope array for the microquasar SS 433 through detailed simulations. Our results indicate that a de…
Performance of LACT Array: Instrument Response Functions and Source Prospects
Zhipeng Zhang, Ruizhi Yang, Shoushan Zhang
Large Array of imaging atmospheric Cherenkov Telescope (LACT) is an array of 32 Cherenkov telescopes with 6-meter diameter mirrors to be constructed at the LHAASO site, aiming to e…
