Diffuse gamma-ray emission around the Rosette Nebula
Jiahao Liu, Bing Liu, Ruizhi Yang
The Rosette Nebula is a young stellar cluster and molecular cloud complex, located at the edge of the southern shell of a middle-aged SNR Monoceros Loop (G205.5+0.5). We revisited…
New estimation of the nuclear de-excitation line emission from the supernova remnant Cassiopeia A
Bing Liu, Rui-zhi Yang, Xin-yu He +1
MeV nuclear de-excitation lines serve as a unique tool to study low-energy cosmic rays (CRs), containing both spectral and elemental information of the interacting material. In thi…
Cosmic ray density variations in nearby giant molecular clouds
Jiahao Liu, Bing Liu, Ruizhi Yang
In this paper, we analyzed 12 years of Fermi LAT gamma-ray data towards three nearby giant molecular clouds (GMCs), i.e., R~CrA, Chamaeleon, and Lupus. We calibrated the gas column…
Effective Shielding of 10 GeV Cosmic Rays from Dense Molecular Clumps
Rui-zhi Yang, Guang-Xing Li, Emma de Oña Wilhelmi +3
The density of cosmic rays inside molecular clouds determines the ionization rate in the dense cores where stars form. It is also one of the drivers of astrochemistry leading to th…
