On Loops in Inflation

Leonardo Senatore, Matias Zaldarriaga

We study loop corrections to correlation functions of inflationary perturbations. Previous calculations have found that the two-point function can have a logarithmic running of the…

Spherical collapse in quintessence models with zero speed of sound

Paolo Creminelli, Guido D'Amico, Jorge Noreña +2

We study the spherical collapse model in the presence of quintessence with negligible speed of sound. This case is particularly motivated for w<-1 as it is required by stability. A…

Non-Gaussianities in Single Field Inflation and their Optimal Limits from the WMAP 5-year Data

Leonardo Senatore, Kendrick M. Smith, Matias Zaldarriaga

Using the recently developed effective field theory of inflation, we argue that the size and the shape of the non-Gaussianities generated by single-field inflation are generically…

Observing the Evolution of the Universe

James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172

How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…

Trapped Inflation

Daniel Green, Bart Horn, Leonardo Senatore +1

We analyze a distinctive mechanism for inflation in which particle production slows down a scalar field on a steep potential, and show how it descends from angular moduli in string…

Contributions to the Dark Matter 3-Pt Function from the Radiation Era

A. Liam Fitzpatrick, Leonardo Senatore, Matias Zaldarriaga

We consider the contribution to the three-point function of matter density fluctuations from nonlinear growth after modes re-enter the horizon, and discuss effects that must be inc…
