Structure formation by cosmic strings with a cosmological constant
We investigate cosmic string models for structure formation which include a non-zero cosmological constant. We nd that the background evolution of density perturbations and modi cations to the scaling behaviour of the strings both act to increase the amount of power present on 100h Mpc scales. We estimate the size of this e ect using an analytic model for the evolution of the string network and...
متن کاملCosmic strings in a space-time with positive cosmological constant
We study Abelian strings in a fixed de Sitter background. We find that the gauge and Higgs fields extend smoothly across the cosmological horizon and that the string solutions have oscillating scalar fields outside the cosmological horizon for all currently accepted values of the cosmological constant. If the gauge to Higgs boson mass ratio is small enough, the gauge field function has a power-...
متن کاملEffect of a positive cosmological constant on cosmic strings
Abstract We study cosmic Nielsen-Olesen strings in space-times with a positive cosmological constant. For the free cosmic string in a cylindrically symmetric space-time, we calculate the contribution of the cosmological constant to the angle deficit, and to the bending of null geodesics. For a cosmic string in a Schwarzschild-de Sitter space-time, we use Kruskal patches around the inner and out...
متن کاملCosmic Strings and Structure Formation
We discuss structure formation in cosmic string theories. Emphasis is laid on the properties of the peculiar velocity field, non–gaussian features and clusters of galaxies. It is found that the predicted peculiar velocity field is quiet (v < 150 km/s for L > 30h Mpc) for models with (Ω0h ≤ 0.2) which is in disagreement with the results from POTENT at large scales (> 30h Mpc), consistent, howeve...
متن کاملSemi-local Cosmic Strings and the Cosmological Constant Problem
We study the cosmological constant problem in a three-dimensional N = 2 supergravity theory with gauge group SU(2)global × U(1)local. The model we consider is known to admit string-like configurations, the so-called semi-local cosmic strings. We show that the stability of these solitonic solutions is provided by supersymmetry through the existence of a lower bound for the energy, even though th...
