DESCRIPTION:Speakers: Dong-Gang Wang (HKUST)\nOur understanding of the pri
 mordial Universe largely depends on the information from spatial correlati
 ons of cosmic-scale matter distributions. Recently\, the advances of the 
 “cosmological bootstrap” program offers new perspectives and powerful 
 tools to study these cosmological correlators. In this talk\, I will revie
 w the exciting developments along this direction\, with a focus on the phe
 nomenology and observation frontiers. I will first systematically classify
  the primary observational target — primordial non-Gaussianities (bispec
 trum) from cosmic inflation\, incorporating three leading scenarios: singl
 e field inflation\, cosmological colliders and multi-field inflation. Then
 \, I will introduce the recent efforts to bootstrap graviton non-Gaussiani
 ties from massive spinning fields. In the end\, I will present an up-to-da
 te data analysis of the new predictions using the latest CMB data from Pla
 nck satellite. Via both CMB-BEST and Modal pipelines\, we identify the mos
 t significant signal of cosmological collider in the current observation.\
