StreamingInstabilityMesoscale Disk Structures

Ionized disks are turbulent due to the magnetorotational instability (MRI). This turbulence generates structures on small scales (less than a vertical scale height), and has therefore been frequently studied in the local limit, focusing on a co-rotating disk patch.

By comparing these local disk patch simulations with global simulations, my colleagues and I have explored the formation and evolution of large scale structures that emerge from the disk turbulence.
