"New Cosmic String Simulations and their Implications"


Vitaly Vanchurin
Tufts University

Abstract:

We study the spectrum of loops as a part of a complete network of cosmic strings. After a long transient regime, characterized by production of small loops at the initial correlation scale, it appears that a true scaling regime takes over! We find that loops are produced in a wide range of sizes with most of the string length going into relatively large loops, comparable to the inter-string distance. New strings scenario leads to enhancement of observational effects, such as gravitational wave bursts and gamma ray bursts. Other cosmological implications are also discussed.
