DESCRIPTION:Speakers: Valerio Faraoni (Bishop's University)\nThe concept o
 f turnaround radius in an accelerating universe is generalized to arbitrar
 ily large deviations from spherical symmetry\, as needed for astronomical 
 observations. As an application\, the turnaround surface is characterized 
 when deviations from spherical symmetry are small and is extended to scala
 r-tensor gravity. An independent approach for small non-sphericities using
  the Hawking quasilocal energy produces the same result.\n[Based on A Gius
