Abstract

We discuss the cosmological evolution of cosmic strings with time-dependent tension. We show that, in the case that the tension changes as a power of time, the cosmic string network obeys the scaling solution: the characteristic scale of the string network grows with the time. But due to the time dependence of the tension, the ratio of the energy density of infinite strings to that of the background universe is not necessarily constant.

Implications of cosmic strings with time-varying tension on the CMB and large scale structure

Journal Article Ichikawa, Kazuhide; Takahashi, Tomo; Yamaguchi, Masahide - Physical Review. D, Particles Fields

We investigate cosmological evolution and implications of cosmic strings with time-dependent tension. We derive basic equations of time development of the correlation length and the velocity of such strings, based on the one-scale model. Then, we find that, in the case where the tension depends on some power of the cosmic time, cosmic strings with time-dependent tension goes into the scaling solution if the power is lower than a critical value. We also discuss cosmic microwave background anisotropy and matter power spectra produced by these strings. The constraints on their tensions from the Wilkinson microwave anisotropy probe (WMAP) 3 yrmore »« less

Cosmic strings in an open universe: Quantitative evolution and observational consequences

Journal Article Avelino, P; Caldwell, R; Martins, C - Physical Review, D

The cosmic string scenario in an open universe is developed{emdash}including the equations of motion, a model of network evolution, the large angular scale cosmic microwave background (CMB) anisotropy, and the power spectrum of density fluctuations produced by cosmic strings with dark matter. We first derive the equations of motion for a cosmic string in an open Friedmann-Robertson-Walker (FRW) space-time. With these equations and the cosmic string stress-energy conservation law, we construct a quantitative model of the evolution of the gross features of a cosmic string network in a dust-dominated, {Omega}{lt}1 FRW space-time. Second, we apply this model of network evolutionmore »« less

Gravitational effects of cosmic strings in Friedmann universes

Thesis/Dissertation Veeraraghavan, S

Cosmic strings have been invoked recently as a possible source of the primordial density fluctuations in matter which gave rise to large-scale structure by the process of gravitational collapse. If cosmic strings did indeed seed structure formation then they would also leave an observable imprint upon the microwave and gravitational wave backgrounds, and upon structure on the very largest scales. In this work, the energy-momentum tensor appropriate to a cosmic string configuration in the flat Friedmann universe is first obtained and then used in the linearized Einstein equations to obtain the perturbations of the background space-time and the ambient matter.more »« less
Cosmic string evolution in higher dimensions

Journal Article Avgoustidis, A; Shellard, E - Physical Review. D, Particles Fields

We obtain the equations of motion for cosmic strings in extensions of the 3+1 Friedmann-Robertson-Walker (FRW) model with extra dimensions. From these we derive a generalization of the velocity-dependent one-scale model for cosmic string network evolution which we apply, first, to a higher-dimensional isotropic D+1 FRW model and, second, to a 3+1 FRW model with static flat extra dimensions. In the former case the string network does not achieve a scaling regime because of the diminishing rate of string intersections (D>3), but this can be avoided in the latter case by considering compact, small extra dimensions, for which there ismore »« less

Evolution of a non-Abelian cosmic string network

Journal Article McGraw, P - Physical Review, D

We describe a numerical simulation of the evolution of an S{sub 3} cosmic string network which takes fully into account the noncommutative nature of the cosmic string fluxes and the topological obstructions which hinder strings from moving past each other or intercommuting. The influence of initial conditions, string tensions, and other parameters on the network{close_quote}s evolution is explored. Contrary to some previous suggestions, we find no strong evidence of the {open_quotes}freezing{close_quotes} required for a string-dominated cosmological scenario. Instead, the results in a broad range of regimes are consistent with the familiar scaling law, i.e., a constant number of strings permore »« less
