PIRSA:17050045  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Inflationary and pre-inflationary dynamics with the Starobinsky potential
Speaker(s): Beatrice Bonga
Abstract: Inflation is the leading paradigm of the early Universe, according to which the tiny temperature fluctuations observed in the cosmic microwave background (CMB) originate from quantum vacuum fluctuations at very early times. Recent observations show that the Starobinsky potential is favored among the... read more

PIRSA:16090043  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Surprising consequence of a positive cosmological constant
Speaker(s): Beatrice Bonga
Abstract: The study of isolated systems has been vastly successful in the context of vanishing cosmological constant, $Lambda = 0$. However, there is no physically useful notion of asymptotics for the universe we inhabit with $Lambda > 0$. The full non-linear framework is still under development, but s... read more

Closed universes and the CMB / Spin-SILC: CMB polarisation component separation for next-generation experiments
Abstract: 1. Beatrice Bonga, "Closed universes and the CMB", Abstract: Cosmic microwave background (CMB) observations put strong constraints on the spatial curvature via estimation of the parameter $Omega_k$. This is done assuming a nearly scale-invariant primordial power spectrum. However, we found that ... read more
