Investigating the Origin of CMB Large-Scale Features Using LiteBIRD and CMB-S4
Catherine Petretti, Matteo Braglia, Xingang Chen +2
Several missions following Planck are currently under development, which will provide high-precision measurements of the Cosmic Microwave Background (CMB) anisotropies. Specificall…
Primordial Stochastic Gravitational Wave Backgrounds from a Sharp Feature in Three-field Inflation II: The Inflationary Era
Vikas Aragam, Sonia Paban, Robert Rosati
We study the contribution of large scalar perturbations sourced by a sharp feature during cosmic inflation to the stochastic gravitational wave background (SGWB), extending our pre…
Primordial Stochastic Gravitational Wave Backgrounds from a Sharp Feature in Three-field Inflation I: The Radiation Era
Vikas Aragam, Sonia Paban, Robert Rosati
The detection of a primordial stochastic gravitational wave background has the potential to reveal unprecedented insights into the early universe, and possibly into the dynamics of…
Inflation in Multi-field Modified DBM Potentials
Sonia Paban, Robert Rosati
We study multi-field inflation in random potentials generated via a non-equilibrium random matrix theory process. We make a novel modification of the process to include correlation…
On primordial equation of state transitions
Aditya Aravind, Dustin Lorshbough, Sonia Paban
We revisit the physics of transitions from a general equation of state parameter to the final stage of slow-roll inflation. We show that it is unlikely for the modes comprising the…
Non-Gaussianities in the Cosmological Perturbation Spectrum due to Primordial Anisotropy II
Anindya Dey, Ely D. Kovetz, Sonia Paban
We continue to investigate possible signatures of a pre-inflationary anisotropic phase in two-point and three point correlation functions of the curvature perturbation for high-mom…
