Rethinking the Model of Moving Cosmic Strings Producing Anisotropy in the Microwave Background
نویسندگان
چکیده
We re-analyze the issue of redshifts induced by a moving cosmic string by looking at moving sources and observers on a conical spacetime in a fully relativistic approach. By replacing the concept of a moving spacetime with the more clearly defined concept of moving sources and observers in the string spacetime, we show that there is no effect: the only redshift is a Doppler shift due to the motion of the source or observer. Subject headings: cosmic strings – cosmology: theory – cosmic microwave background

The Implications of the Cobe-dmr Results for Cosmic Strings
We compare the anisotropies in the cosmic microwave background radiation measured by the COBE experiment to the predictions of cosmic strings. We use an analytic model for the ∆T/T power spectrum that is based on our previous numerical simulations to show that the COBE results imply a value for the string mass per unit length, μ under the assumption that cosmic strings are the source of the mea...
متن کاملCosmic String Production Towards the End of Brane Inflation
Towards the end of the brane inflationary epoch in the brane world, cosmic strings (but not texture, domain walls or monopoles) are copiously produced during brane collision. These cosmic strings are Dp-branes with (p−1) dimensions compactified. We elaborate on this prediction of the superstring theory description of the brane world. Using the data on the temperature anisotropy in the cosmic mi...
متن کاملRadiation Anisotropy Induced by Cosmic Strings 12
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of Z = 100 to the present and calculated the anisotropies which they induce. Based on a limited number of realizations, we have compared the results of our simulations with the observa...
متن کاملCMB temperature trispectrum of cosmic strings
We provide an analytical expression for the trispectrum of the cosmic microwave background (CMB) temperature anisotropies induced by cosmic strings. Our result is derived for the small angular scales under the assumption that the temperature anisotropy is induced by the Gott-Kaiser-Stebbins effect. The trispectrum is predicted to decay with a noninteger power-law exponent ‘ with 6< < 7, dependi...
متن کاملA Cosmic String Specific Signature on the Cosmic Microwave
Using an analytical model for the string network we show that the kurtosis of cosmic microwave background (CMB) temperature gradient maps is a good statistic to distinguish between the cosmic string model and inflationary models of structure formation. The difference between the stringy and inflationary value for the kurtosis is inversely proportional to the angular resolution and to the number...
