Massless (pseudo-)scalar seeds of CMB anisotropy
R. Durrer, M. Gasperini, M. Sakellariadou +1
A primordial stochastic background of very weakly coupled massless (pseudo-)scalars can seed CMB anisotropy, when large-scale fluctuations of their stress-tensor re-enter the horiz…

Seeds of large-scale anisotropy in string cosmology
R. Durrer, M. Gasperini, M. Sakellariadou +1
Pre-big bang cosmology predicts tiny first-order dilaton and metric perturbations at very large scales. Here we discuss the possibility that other -- more copiously generated -- pe…
