Gravitational Wave Emission from a Cosmic String Loop, I: Global Case
Jorge Baeza-Ballesteros, Edmund J. Copeland, Daniel G. Figueroa +1
We study the simultaneous decay of global string loops into scalar particles (massless and massive modes) and gravitational waves (GWs). Using field theory simulations in flat spac…
The strong backreaction regime in axion inflation
Daniel G. Figueroa, Joanes Lizarraga, Ander Urio +1
We study the non-linear dynamics of axion inflation, capturing for the first time the inhomogeneity and full dynamical range during strong backreaction, till the end of inflation.…
Nambu-Goto Dynamics of Field Theory Cosmic String Loops
Jose J. Blanco-Pillado, Daniel Jiménez-Aguilar, Joanes Lizarraga +4
We perform a detailed comparison of the dynamics of cosmic string loops obtained in cosmological field theory simulations with their expected motion according to the Nambu-Goto act…
