Turbulence and cosmic accelerators

Turbulence is the most ubiquitous phenomenon shaping diverse processes across all length scales in the universe. Despite its ubiquity and importance, there exists a gap between the ever-improved understanding on turbulence and its application to understanding the extreme universe. I will discuss my efforts in bridging this gap by addressing (1) how turbulence connects the microscopic physics and macroscopic astronomical observations; and (2) how turbulence affects the multi-messenger astronomy and switches on cosmic fireworks. By using shock acceleration as an example, I will illustrate how I use the turbulence toolbox to understand the most energetic events in the universe. In the era of multi-messenger astronomy, the turbulence toolbox provides us a new vision of the extreme universe.
