Power spectra in extended tachyon cosmologies
In the present work the power spectrum of a particular class of tachyon fields is compared with the one corresponding to a cosmological constant model. This is done for different barotropic indexes (Formula presented.) and the background space time is assumed to be of the spatially flat Friedmann–Ro...
