PIRSA:16060010  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Inhomogeneous Anisotropic Cosmology
Speaker(s): Leonardo Senatore
Abstract: In homogeneous and isotropic Friedmann-Robertson-Walker cosmology, the topology of the universe determines its ultimate fate. If the Weak Energy Condition is satisfied, open and flat universes must expand forever, while closed cosmologies can recollapse to a Big Crunch. A similar statement holds ... read more

PIRSA:15080019  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Effective Field Theory of Large Scale Structures
Speaker(s): Leonardo Senatore
Abstract: After the completion of the Planck satellite, the next most important experiments in cosmology will be about mapping the Large Scale Structures of the Universe. In order to continue to make progress in our understanding of the early universe, it is essential to develop a precise understanding of thi... read more

PIRSA:14090041  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Effective Field Theory of Cosmological Large Scale Structures
Speaker(s): Leonardo Senatore
Abstract: The Effective Filed Theory of Large Scale Structures provides a novel framework to analytically compute the clustering of the Large Scale Structures in the weakly non-linear regime in a consistent and reliable way. The theory that describes the long wavelength fluctuations is obtained after integrat... read more

PIRSA:09030038  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Acceleration in our past, present, and future
Speaker(s): Leonardo Senatore
Abstract: The great advances in observational cosmology in the last few years have delivered us an unprecedented amount of new data. They begin to indicate with confidence that in the past our universe underwent a phase of acceleration, called inflation, and that it is currently undergoing a similar phase, us... read more

PIRSA:08110034  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Volume of the Universe after Inflation and de Sitter Entropy
Speaker(s): Leonardo Senatore
Abstract: I will show the calculation of the probability distribution for the volume of the Universe after slow-roll inflation both in the eternal and the non-eternal regime. Far from the eternal regime the probability distribution for the number of e-foldings, defined as one third of the logarithm of the vol... read more

PIRSA:08050006  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Effective Field Theory of Inflation.
Speaker(s): Leonardo Senatore
Abstract: We study the effective field theory of inflation, i.e. the most general theory describing the fluctuations around a quasi de Sitter background, in the case of single field models. The scalar mode can be eaten by the metric by going to unitary gauge. In this gauge, the most general theory is built wi... read more
