Title: First observational tests of eternal inflation
Date: Thursday, October 20th, 2011
Time: 16:30
Venue: ICTP - Euler Lecture Room (Leonardo building)

Abstract: The eternal inflation scenario predicts that our observable universe resides inside a single bubble embedded in a vast inflating multiverse. Collisions between bubble universes imprinted in the CMB sky provide a powerful observational test of this idea. I will describe a robust algorithm for non-Gaussian source detection in massive datasets, and present its application to the search for bubble collision signatures in CMB data from WMAP.
