DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMU-TP/35/">
 Primordial nongaussianities from consistency relations: a proof of princip
 le</a>\nby Angelo Esposito (IAS) as part of Carnegie Mellon theoretical ph
 ysics\n\n\nAbstract\nConsistency relations are the cosmological analogues 
 of the soft pion theorem\, connecting the soft limit of certain correlator
 s to other correlators. Due to their nonperturbative nature\, they remain 
 true also in fully nonlinear regimes (where the standard approach fails)\,
  and for astrophysically messy observables (like galaxy distributions).\nI
 n this seminar I will discuss how we can use the consistency relations for
  large scale structures to determine whether or not inflation was driven b
 y the dynamics of a single field. I will do that using a suite of N-body s
 imulations for the matter distributions\, and discuss how to extend this t
 o a more realistic scenario.\n
