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…
Cosmological Background Interpretation of Pulsar Timing Array Data
Daniel G. Figueroa, Mauro Pieroni, Angelo Ricciardone +1
We discuss the interpretation of the detected signal by Pulsar Timing Array (PTA) observations as a gravitational wave background (GWB) of cosmological origin. We combine NANOGrav…
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.…
Stochastic gravitational wave background from stellar origin binary black holes in LISA
Stanislav Babak, Chiara Caprini, Daniel G. Figueroa +7
We use the latest constraints on the population of stellar origin binary black holes (SOBBH) from LIGO/Virgo/KAGRA (LVK) observations, to estimate the stochastic gravitational wave…
Gravitational wave production from preheating with trilinear interactions
Catarina Cosme, Daniel G. Figueroa, Nicolas Loayza
We investigate the production of gravitational waves (GWs) during preheating with monomial/polynomial inflationary potentials, considering a trilinear coupling between a dau…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
