# Non-Gaussianity in the Cosmic Microwave Background temperature fluctuations from cosmic (super-)strings

@article{Takahashi2008NonGaussianityIT, title={Non-Gaussianity in the Cosmic Microwave Background temperature fluctuations from cosmic (super-)strings}, author={Keitaro Takahashi and Atsushi Naruko and Yuuiti Sendouda and Daisuke Yamauchi and Chul-Moon Yoo and Misao Sasaki}, journal={Journal of Cosmology and Astroparticle Physics}, year={2008}, volume={2009}, pages={003-003} }

We compute analytically the small-scale temperature fluctuations of the cosmic microwave background from cosmic (super-)strings and study the dependence on the string intercommuting probability P. We develop an analytical model which describes the evolution of a string network and calculate the numbers of string segments and kinks in a horizon volume. Then we derive the probability distribution function (pdf) which takes account of finite angular resolution of observation. The resultant pdf…
