Cosmic Ray Transport and Gamma-Ray Signatures in the Interstellar Medium
Lucas Barreto-Mota, Elisabete M. de Gouveia Dal Pino, Siyao Xu +4
The interaction of cosmic rays (CRs) with magnetic fields and the interstelar medium (ISM) leads to the production of nonthermal radiation. Although this has been a topic of study…
Probing Turbulence, Gravity, Supernovae, and Magnetic Field Effects with the 6D Kinematics of Young Stars in Milky Way Star-Forming Regions
Benjamin N. Velguth, Yuan Li, Trung Ha +6
The dynamics of star forming gas can be affected by many physical processes, such as turbulence, gravity, supernova explosions, and magnetic fields. In this paper, we investigate s…
Studying the diffusion mechanism of cosmic-ray particles
Yawen Xiao, Jianfu Zhang, Siyao Xu
More and more observations have indicated the existence of slow diffusion phenomena in astrophysical environments, such as around the supernova remnants and pulsar -ray halos, w…
Dynamics of Multiphase Carbon in the Turbulent Circumgalactic Medium
Yue Hu, Evan Scannapieco, Edward Buie +3
The circumgalactic medium (CGM) plays a crucial role in regulating material and energy exchange between galaxies and their environments. The best means of observing this medium is…
Cosmic Ray Perpendicular Superdiffusion and Parallel Mirror Diffusion in a Partially Ionized and Turbulent Medium
Yue Hu, Siyao Xu, Alex Lazarian +2
Understanding cosmic ray (CR) diffusion in a partially ionized medium is both crucial and challenging. In this study, we investigate CR perpendicular superdiffusion and parallel tr…
