Eigenvalue formulation of Stochastic Inflation and application to large perturbation generating inflationary features
Swagat S. Mishra, Edmund J. Copeland, Anne M. Green
Stochastic inflation is a powerful technique for calculating the probability distribution function (PDF) of large inflationary perturbations, which may collapse to form Primordial…
The stochastic gravitational wave background from cosmic superstrings
Anastasios Avgoustidis, Edmund J. Copeland, Adam Moss +1
We study the stochastic gravitational wave background sourced by a network of cosmic superstrings and demonstrate that incorporating higher-mass string species, beyond the fundamen…
Scaling solutions as Early Dark Energy resolutions to the Hubble tension
Edmund J. Copeland, Adam Moss, Sergio Sevillano Muñoz +1
A wide class of scalar field models including Quintessence and K-essence have the attractive property of tracker regimes, where the energy density stored in the field evolves so as…
Constraints on the fundamental string coupling from B-mode experiments
Anastasios Avgoustidis, Edmund J. Copeland, Adam Moss +3
We study signatures of cosmic superstring networks containing strings of multiple tensions and Y-junctions, on the cosmic microwave background (CMB) temperature and polarisation sp…
The effect of kinematic constraints on multi-tension string network evolution
A. Avgoustidis, E. J. Copeland
We consider the evolution of a network of strings in an expanding universe, allowing for the formation of junctions between strings of different tensions. By explicitly including,…
Kinks and small-scale structure on cosmic strings
E. J. Copeland, T. W. B. Kibble
We discuss some hitherto puzzling features of the small-scale structure of cosmic strings. We argue that kinks play a key role, and that an important quantity to study is their sha…
