We examine which information on the early cosmological history can be extracted from the
potential measurement by third-generation gravitational-wave observatories of a stochastic …

Motivated by the fact that cosmological perturbations of inflationary quantum origin were
born Gaussian, the search for non‐Gaussianities in the cosmic microwave background …

If cosmic strings are formed in the early universe, their associated loops emit gravitational
waves during the whole cosmic history and contribute to the stochastic gravitational wave …

We analytically derive the expected number density distribution of Nambu-Goto cosmic
string loops at any redshift soon after the time of string formation to today. Our approach is …

Classical lattice simulations of the Abelian Higgs model are used to investigate small-scale
structure and loop distributions in cosmic string networks. Use of the field theory ensures that …

Third generation ground-based gravitational wave (GW) detectors, such as Einstein
Telescope and Cosmic Explorer, will operate in the (few-104) Hz frequency band, with a …

We investigate cosmic sparks from cusps on superconducting cosmic strings in light of the
recently discovered millisecond radio burst by Lorimer et al.. We find that the observed …

Abstract Numerical simulations of Nambu-Goto cosmic strings in an expanding universe
show that the loop distribution relaxes to an universal configuration, the so-called scaling …

We extend our earlier model of the small-scale structure of cosmic string networks through
an improved treatment of the separation of long and short scales. We find that the production …
