We report the first investigation of cool-core properties of galaxy clusters selected via their Sunyaev--Zel'dovich (SZ) effect. We use 13 galaxy clusters uniformly selected from 178 deg^2 observed wi...

Cold fronts - sharp discontinuities recently discovered by Chandra in many clusters of galaxies - are believed to be due to a hot gas flow over a colder gravitationally bound gas cloud. We analyze the...
