Measurement of Cosmic-Ray Density in the Spiral Arms toward Galactic Anticenter
Jia-hao Liu, Bing Liu, Rui-zhi Yang
Using nearly 17 years of Fermi-LAT data, we analyzed the diffuse gamma-ray emission associated with different spiral arms of the Milky Way in the ranges to $145^\ci…
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…
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…
