SUMMARY:The secret lives of Galaxy Clusters\, Astronomy Colloquium\, B
 rian O'shea\, Michigan State University
DESCRIPTION:Galaxy clusters have the potential to be highly accurate p
 robes of cosmological parameters. However\, they are also very interes
 ting astrophysical objects in their own right! The properties that mak
 e clusters irritating to those who wish to use them for cosmology - de
 viations from sphericity and hydrostatic equilibrium\, shocks\, merger
 s\, and a variety of baryonic processes - provide a tremendous amount 
 of information about these massive beasts. I will present recent effor
 ts to understand the effects that correctly modeling the properties of
  gas in cosmological simulations have on the observable properties of 
 clusters\, focusing on shocks\, AGN heating\, and the non- thermal com
 ponents of the intracluster medium\, including cosmic rays and magneti
 c fields.
