This is a set of 50 maps with 128^{2} pixels of the
Kaiser-Stebbins effect. The size of the fields are approximately 2
degrees. These maps are made under the following simplifying
assumptions
- The cosmic string network is evolved in Minkowski space (see Coulson et al ).
- The Minkowski space Einstein equations are solved to first order (see Borrill et al for the formalism)
- The last scattering surface is assumed to be perfectly homogeneous
To obtain a normalized map you must multiply by 200Gu (where G
is Newtons constant and u is the mass per unit length of the network).
Current values for Gu are 1-3x10 There are 5 files containing the data for 10 maps each: 1 2 3 4 5 |

This is work in progress.
Shown here is a preliminary example of a 5 degree field,
128 The color scale indicates standard deviations from the mean. The non-gaussianity reveals itself in the presence of high sigma hot and cold spots, thought to be characteristic of textures. An accurate estimate of the frequency distribution of such peaks would provide a powerful observational test of this model. |
