Title : Testing statistical isotropy of the universe with cosmological fields - a geometrical perspective
Authors : Pravabati Chingangbam
Abstract Type: Invited
Abstract Category : Plenary
Abstract : We present a new method for testing the statistical isotropy of the universe based on the geometrical properties of level sets of cosmological fields. We apply the method to CMB temperature, polarization and the inferred lensing potential data from Planck, and isolate sky patches where we find hints of departure from statistical isotropy.
