Abstract

The search for cosmic strings has been of renewed interest with the advent of precision cosmology. In this note we give a quantitative description of the nonlinear matter density fluctuations that can form from a scaling network of cosmic string wakes. Specifically, we compute the distribution of dark matter halos. These halos would possess strong correlations in position space that should have survived until today. We also discuss the challenges involved in their detection due to their small size and the complex dynamics of their formation.

Cosmic string wakes

Journal Article Stebbins, A; Veeraraghavan, S; Silk, J; ... - Astrophys. J.; (United States)

Accretion of matter onto wakes left behind by horizon-sized pieces of cosmic string is investigated, and the effects of wakes on the large-scale structure of the universe are determined. Accretion of cold matter onto wakes, the effects of a long string on fluids with finite velocity dispersion or sound speeds, the interactions between loops and wakes, and the conditions for wakes to survive disruption by loops are discussed. It is concluded that the most important wakes are those which were formed at the time of equal matter and radiation density. This leads to sheetlike overdense regions of galaxies with amore »« 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

Cosmic strings, hot dark matter and the large-scale structure of the universe

Journal Article Brandenberger, R; Perivolaropoulos, L; Stebbins, A - International Journal of Modern Physics A; (USA)

A review of recent results on large-scale structure and galaxy formation in a model with hot dark matter and cosmic strings is given. With cosmic strings seeding perturbations, many of the arguments against hot dark matter disappear. It is shown that spherical accretion about loops leads to dark matter haloes with flat velocity rotation curves. Velocity perturbations due to wakes behind long, moving strings lead to a network of planar overdensities with a distinguished scale of slightly less than 40 {times} 40 Mpc{sup 2}. If the mass per unit length {mu} exceeds a certain bound, then the wakes become nonlinearmore »« less

Cosmic strings, neutrinos and the large-scale structure of the universe

Conference Brandenberger, R - AIP Conference Proceedings (American Institute of Physics); (United States)

A cosmological model in which the energy density perturbations are seeded by cosmic strings and in which the dark matter is hot (e.g. neutrinos with a mass of 25{ital h}{sup 2}{sub 50} {ital eV}) produces large-scale structure dominated by planar overdensities with mean radius and separation determined by the comoving horizon at the time of equal matter and radiation (about 40{ital h}{sup {minus}2}{sub 50} Mpc). The planar overdensities are the consequence of the velocity perturbations in the wake of long rapidly moving strings. As a consequence of dark matter being hot, clustering about cosmic string loops is suppressed, leading tomore »« less
Galaxy formation with cosmic strings and massive neutrinos

Journal Article Bertschinger, E; Watts, P - Astrophys. J.; (United States)

A detailed calculation of the growth of linear density perturbations induced by a loop of cosmic string in a universe presently dominated by light massive neutrinos is presented. The constant pulling of the cosmic string overcomes free-streaming damping so that cosmological structure develops in a bottom-up fashion different from hot dark matter scenarios without cosmic strings. An accurate semianalytic method for evolving the spherical perturbation around a loop through the collapse stage is developed. Applying this method, it is shown that halos with flat rotation curves form with circular rotation speed of about 50 km/s or greater. The Tremaine andmore »« less
