Statistical measurements of astrophysical turbulence

Abstract:

Turbulence is ubiquitous in the universe across a vast range of length scales and actively participates in diverse astrophysical processes, such as star formation, cosmic ray diffusion, dynamo amplification of cosmic magnetic fields, magnetic reconnection in high-energy astrophysical environments. Despite their scientific significance, direct measurements of turbulence in most astrophysical environments are challenging. I will introduce several new methods for statistical measurements of astrophysical turbulence from the interstellar medium to the intergalactic medium. They are important for revealing the fundamental properties of astrophysical turbulence and understanding its roles in a variety of astrophysical processes.
