Webinar “Primordial Black Holes- From formation to detection”

The speaker will present recent work on the formation of primordial black hole dark matter and the resultant Gravitational Wave(GW) signal, in which her collaborators and her performed an Markov Chain Monte Carlo(MCMC) analysis of a simple—yet generic—multifield inflation model characterized by two scalar fields coupled to each other and non-minimally coupled to gravity. The model was fit to the Planck 2018 Cosmic Microwave Background(CMB) data. In particular, model parameters are constrained by data on the amplitude of the primordial power spectrum of scalar curvature perturbations on CMB scales
