Nuclear de-excitation line emissions from giant molecular clouds
Zhaodong Shi, Bing Liu, Rui-zhi Yang
Understanding how cosmic rays (CRs) propagate within the giant molecular clouds (GMCs) is critical for studying the dynamics and chemical processes inside the clouds. The flux of l…
Low-Energy Cosmic Rays and Associated MeV Gamma-Ray Emissions in the Protoplanetary System
Xulei Sun, Shuying Zheng, Zhaodong Shi +2
Low-energy cosmic rays (LECRs) play a crucial role in the formation of planetary systems, and detecting and reconstructing the properties of early LECRs is essential for understand…
Constraining the low-energy cosmic ray flux in the central molecular zone from MeV nuclear deexcitation line observations
Bing Liu, Ruizhi Yang
Low-energy cosmic rays (LECRs) dominate the ionization in dense regions of molecular clouds in which other ionizers such as UV or X-ray photons are effectively shielded. Thus it wa…
Precise measurement of pion-bump structure using future MeV gamma-ray detectors
Jiahao Liu, Bing Liu, Ruizhi Yang
The pion-bump structure in the gamma-ray spectrum is a direct proof for the hadronic origin of the gamma rays, and thus the decisive evidence for the acceleration of hadronic cosmi…
Detection of extended gamma-ray emission in the vicinity of Cl Danks 1 and 2
Jiahao Liu, Bing Liu, Ruizhi Yang
We report the detection of high-energy gamma-ray emission towards the G305 star-forming region. Using almost 15 years of observation data from {\sl Fermi} Large Area Telescope, we…
Limits on the Primordial Black Holes Dark Matter with future MeV detectors
Zhen Xie, Bing Liu, Jiahao Liu +2
Primordial black holes (PBHs) are a compelling candidate for Dark Matter (DM). There remain significant parameter spaces to be explored despite current astrophysical observations h…
Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
