       "Stability of cold fronts in clusters of galaxies" E. Churazov (IKI, MPA) Abstract: One of the insteresting results of Chandra and XMM-Newton observatories is the discovery of sharp structures in the X-ray surface
      brightness of galaxy clusters. These structures (a.k.a. cold fronts) are likely associated with the contacted discontinuities formed when a hot gas flows over a colder gravitationally bound gas cloud. The stability of these discontinuities is
      discussed.
