Spectral Analysis of Microwave Background Perturbations Induced by Cosmic Strings
Using a simple analytic model based on seed superposition we obtain the spectrum of microwave background perturbations induced by cosmic strings on all angular scales larger than about 2 armin. We assume standard recombination in an Einstein de Sitter universe with h = 1/2 and study the fluctuation spectrum along a great circle in the sky. Doppler and potential perturbations on the last scatter...
متن کاملSuperhorizon perturbations and the cosmic microwave background
Superhorizon perturbations induce large-scale temperature anisotropies in the cosmic microwave background (CMB) via the Grishchuk-Zel’dovich effect. We analyze the CMB temperature anisotropies generated by a single-mode adiabatic superhorizon perturbation. We show that an adiabatic superhorizon perturbation in a CDM universe does not generate a CMB temperature dipole, and we derive constraints ...

متن کاملFitting cosmic microwave background data with cosmic strings and inflation.
We perform a multiparameter likelihood analysis to compare measurements of the cosmic microwave background (CMB) power spectra with predictions from models involving cosmic strings. Adding strings to the standard case of a primordial spectrum with power-law tilt ns, we find a 2sigma detection of strings: f10=0.11+/-0.05, where f10 is the fractional contribution made by strings in the temperatur...
