Modern Cosmology : Academic Press : 9780128159484 : 0128159480 : 07 Jul 2020 : Modern Cosmology, Second Edition, provides a detailed introduction to the field of cosmology. Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaãitre-Robertson-Walker metric, this trusted resource includes careful treatments ofdark energy, big bang nucleosynthesis, recombination, and dark matter. The reader is then introduced to perturbations about an FLRW universe: their evolution with the Einstein-Boltzmann equations, their primordial generation by inflation, and their observational consequences: the acoustic peaks in the CMB; the E/B decomposition in polarization; gravitational lensing of the CMB and large-scale structure; and the BAO standard ruler and redshift-space distortions in galaxy clustering. The Second Edition nowalso covers nonlinear structure formation including perturbation theory and simulations. The book concludes with a substantially updated chapter on data analy
