Universal Weak Lensing Distortion of Cosmological Correlation Functions
Scott Dodelson, Fabian Schmidt, Alberto Vallinotto
Gravitational lensing affects observed cosmological correlation functions because observed images do not coincide with true source locations. We treat this universal effect in a ge…
Weak Lensing Effects on the Galaxy Three-Point Correlation Function
Fabian Schmidt, Alberto Vallinotto, Emiliano Sefusatti +1
We study the corrections to the galaxy three-point correlation function (3PCF) induced by weak lensing magnification due to the matter distribution along the line of sight. We cons…
Weak Lensing of Baryon Acoustic Oscillations
Alberto Vallinotto, Scott Dodelson, Carlo Schimd +1
Baryon Acoustic Oscillations (BAO) have recently been observed in the distribution of distant galaxies. The height and location of the BAO peak are strong discriminators of cosmolo…
Non-Gaussianity from Broken Symmetries
Edward W. Kolb, Antonio Riotto, Alberto Vallinotto
Recently we studied inflation models in which the inflaton potential is characterized by an underlying approximate global symmetry. In the first work we pointed out that in such a…
Curvature Perturbations from Broken Symmetries
Edward W. Kolb, Antonio Riotto, Alberto Vallinotto
We present a new general mechanism to generate curvature perturbations after the end of the slow-roll phase of inflation. Our model is based on the simple assumption that the poten…
Inflationary potentials yielding constant scalar perturbation spectral indices
Alberto Vallinotto, Edmund J. Copeland, Edward W. Kolb +2
We explore the types of slow-roll inflationary potentials that result in scalar perturbations with a constant spectral index, i.e., perturbations that may be described by a single…
