TASI Lectures on Cosmological Perturbations

Understand

We present a self-contained summary of the theory of linear cosmological perturbations.

• We emphasize the effect of the six parameters of the minimal cosmological model, first, on the spectrum of Cosmic Microwave Background temperature anisotropies, and second, on the linear matter power spectrum.
• We briefly review at the end the possible impact of a few non-minimal dark matter and dark energy models.
