The Primordial Density Perturbation

This graduate-level textbook gives a thorough account of theoretical cosmology and perturbations in the early Universe, describing their observational consequences and showing how to relate such observations to primordial physical processes, particularly cosmological inflation. With ambitious observational programs complementing ever-increasing sophistication in theoretical modeling, cosmological studies will remain at the cutting edge of astrophysical studies for the foreseeable future.
