Cosmology Lunchtime Seminar

Monday, December 5th 2016
12:15 pm:
Speaker: Larry Rudnick (University of Minnesota)
Subject: Observational Tracers of Diffuse Baryon Dynamics in Clusters of Galaxies

Clusters of galaxies form at the intersection of the enormous filamentary structures of the cosmic web, and evolve through the continued infall of material along those filaments, with occasional major mergers between clusters. Or so the numerical simulations to be discussed next week by Tom Jones, tell us. The history of that evolution should be embedded in the current dynamical state of the intracluster medium (ICM), but our best tools, the thermal X-ray emission from the hot plasma, are often blind to these structures. I will discuss some of the indicators of ICM dynamics that are available using synchroton emission, what we have learned so far, and some prospects for the future.

The weekly calendar is also available via subscription to the physics-announce mailing list, and by RSS feed.
