The Lagrangian-space Effective Field Theory of Large Scale Structures
Rafael A. Porto, Leonardo Senatore, Matias Zaldarriaga
We introduce a Lagrangian-space Effective Field Theory (LEFT) formalism for the study of cosmological large scale structures. Unlike the previous Eulerian-space construction, it is…
The Effective Field Theory of Large Scale Structures at Two Loops
John Joseph M. Carrasco, Simon Foreman, Daniel Green +1
Large scale structure surveys promise to be the next leading probe of cosmological information. It is therefore crucial to reliably predict their observables. The Effective Field T…
Inflation after False Vacuum Decay: Observational Prospects after Planck
Raphael Bousso, Daniel Harlow, Leonardo Senatore
We assess two potential signals of the formation of our universe by the decay of a false vacuum. Negative spatial curvature is one possibility, but the window for its detection is…
Inflation Physics from the Cosmic Microwave Background and Large Scale Structure
K. N. Abazajian, K. Arnold, J. Austermann +91
Fluctuations in the intensity and polarization of the cosmic microwave background (CMB) and the large-scale distribution of matter in the universe each contain clues about the natu…
The Physical Squeezed Limit: Consistency Relations at Order q^2
Paolo Creminelli, Ashley Perko, Leonardo Senatore +2
In single-field models of inflation the effect of a long mode with momentum q reduces to a diffeomorphism at zeroth and first order in q. This gives the well-known consistency rela…
Optimal analysis of azimuthal features in the CMB
Stephen Osborne, Leonardo Senatore, Kendrick Smith
We present algorithms for searching for azimuthally symmetric features in CMB data. Our algorithms are fully optimal for masked all-sky data with inhomogeneous noise, computational…
