Search for Cosmic Strings in CMB Anisotropies

چکیده
We have searched the 1st-year WMAP W-Band CMB anisotropy map for evidence of cosmic strings. We have set a limit of δ = 8πGμ/c < 8.2× 10 at 95% CL for statistical search for a significant number of strings in the map. We also have set a limit using the uniform distribution of strings model in the WMAP data with δ = 8πGμ/c < 7.34 × 10 at 95% CL. And the pattern search technique we developed here set a limit δ = 8πGμ/c < 1.54× 10 at 95% CL. Subject headings: CMB anisotropy, cosmic strings

Lensing and CMB Anisotropies by Cosmic Strings at a Junction
The metric around straight arbitrarily-oriented cosmic strings forming a stationary junction is obtained at the linearized level. It is shown that the geometry is flat. The sum rules for lensing by this configuration and the anisotropies of the CMB are obtained.
متن کاملDetection and discrimination of cosmological non-Gaussian signatures by multi-scale methods
Recent Cosmic Microwave Background (CMB) observations indicate that the temperature anisotropies arise from quantum fluctuations in the inflationary scenario. In the simplest inflationary models, the distribution of CMB temperature fluctuations should be Gaussian. However, non-Gaussian signatures can be present. They might have different origins and thus different statistical and morphological ...
متن کاملLarge scale CMB anomalies from thawing cosmic strings
Cosmic strings formed during inflation are expected to be either diluted over super-Hubble distances, i.e., invisible today, or to have crossed our past light cone very recently. We discuss the latter situation in which a few strings imprint their signature in the Cosmic Microwave Background (CMB) Anisotropies after recombination. Being almost frozen in the Hubble flow, these strings are quasi ...

متن کاملCMB temperature bispectrum induced by cosmic strings
The cosmic microwave background (CMB) bispectrum of the temperature anisotropies induced by a network of cosmic strings is derived for small angular scales, under the assumption that the principal cause of temperature fluctuations is the Gott-Kaiser-Stebbins effect. We provide analytical expressions for all isosceles triangle configurations in Fourier space. Their overall amplitude is amplified...
