Evolution of Cosmic String Loops under Gravitational Backreaction
Lasse Gerblich, Richard A. Battye, E. P. S. Shellard
Nambu-Goto cosmic string loops generically develop cusps, points where the string momentarily reaches the speed of light. These cusps produce strong gravitational wave bursts with…
A Modal Approach to Constrain Inflation through Numerical Bispectra
Bowei Zhang, E. P. S. Shellard, James R. Fergusson
Constraining inflationary models with high precision bispectra across broad parameter ranges is a challenging task, requiring intensive computations at all stages, first, predictin…
Stochastic Inflation in Numerical Relativity
Yoann L. Launay, Gerasimos I. Rigopoulos, E. Paul S. Shellard
A set of 3+1 equations for stochastic inflation incorporating all metric and scalar matter degrees of freedom, first presented in previous work, are re-derived in a gauge invariant…
How Significant are Cosmological Collider Signals in the Planck Data?
Petar Suman, Dong-Gang Wang, Wuhyun Sohn +2
The search for primordial non-Gaussianities (PNG) is theoretically well motivated but remains observationally challenging. Tight constraints with low significance for the standard…
Bunch-Davies initial conditions and non-perturbative inflationary dynamics in Numerical Relativity
Yoann L. Launay, Gerasimos I. Rigopoulos, E. Paul S. Shellard
We show that it is possible to simulate realistic inhomogeneities during cosmological inflation with high precision using {Numerical Relativity}. Stochastic initial conditions are…
Fully-relativistic evolution of vacuum tensor inhomogeneities during inflation
Ericka Florio, E. Paul S. Shellard
We present a complete method for the initialisation and extraction of first-order inflationary tensor perturbations for fully relativistic simulations which incorporate gravitation…
