DESCRIPTION:Theoretical models of simple spherical collapse pr
 edict that dynamics of matter during collapse of d
 ark matter halos  gives rise to sharp features - “
 edges” - in radial density profiles of matter. I w
 ill show that such sharp edges are detectable arou
 nd real LCDM halos despite the added complexities 
 of their collapse and will argue that these edges 
 are a natural physical boundary of halos. I will d
 iscuss their recent observational detections  arou
 nd real galaxy clusters and will show some example
 s of how splashback feature in matter and galaxy d
 istribution can help with interpretation of galaxy
  evolution and dynamics.
