We simulate maps of the microwave background radiation for a model of inflationary primordial voids plus standard cold dark matter. For some values of the parameters, we find in the angular power spectrum a well-defined second peak at l~1000, correlated with the size, amplitude, and number of the primordial voids. The next generation of microwave background maps will be able to test the scenario of inflationary first-order phase transitions.

Abstract
We simulate maps of the microwave background radiation for a model of inflationary primordial voids plus standard cold dark matter. For some values of the parameters, we find in the angular power spectrum a well-defined second peak at l~1000, correlated with the size, amplitude, and number of the primordial voids. The next generation of microwave background maps will be able to test the scenario of inflationary first-order phase transitions.File in questo prodotto:
