The Nature and Fate of Cool, Clumpy CGM Gas

What are the types of structures that populate the circumgalactic medium? How long-lived are these structures?

 
 

Led by UW graduate student Akaxia Cruz, we are using simulations to study the distribution of cloud sizes and masses in the circumgalactic medium over cosmic time. We find that the vast majority of these clouds are moving toward the galaxy, and are continually replenished by ongoing feedback processes.
