From precision to accuracy: cosmology with large imaging surveys
Speaker(s): Hiranya Peiris
Abstract: Photometric surveys are often larger and extend to fainter magnitudes than spectroscopic samples, and can therefore yield more precise cosmological measurements. However, photometric data are significantly contaminated by multiple sources of systematics, either intrinsic, observati... read more

First observational tests of eternal inflation
Speaker(s): Hiranya Peiris
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-Gau... read more

Fingerprints of the early universe
Speaker(s): Hiranya Peiris
Abstract: I will review recent progress in testing with cosmological data the inflationary hypothesis for describing the very early universe. I will present snapshots of different aspects of confronting the theory with data, including a 'bottom-up' approach: the latest results from a systematic reconstruction... read more
