Cosmic Microwave Background non-Gaussian signatures from analytical texture models

Abstract

Using an analytical model for the Cosmic Microwave Background anisotropies produced by textures, we compute the resulting collapsed three--point correlation function and the {\it rms} expected value due to the cosmic variance. We apply our calculations to the {\sl COBE}--DMR experiment and test the consistency of the model with the observational results. We also show that an experiment with smaller angular resolution can put bounds to the model parameters.Comment: 13 pp, RevTeX, 4 PostScript figures, to appear in Phys.Rev.
