Star Formation Drives Production of Low Energy Cosmic Rays
Ningyu Tang, Jiahao Liu, Di Li +18
For over a century, the origin of low-energy cosmic rays (LECRs), the dominant heaters and ionizers of dense interstellar gas, remains elusive owing to solar modulation and uncerta…

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…
