  Abstract:
We examine the two-point correlation function (TPCF) of local maxima in temperature fluctuations at the last scattering surface when this stochastic field is modified by the additional fluctuations produced by straight cosmic strings via the Kaiser-Stebbins effect. We demonstrate that one can detect the imprint of cosmic strings with tension Gμ >~1.2 ×10−8 on noiseless 1′ resolution CMB maps at 95
