Cosmology and Dark Matter

TL;DR

This lecture course explores cosmology focusing on evidence for new physics like dark matter and dark energy, discussing models, observational data, and the universe's origins from a particle physics perspective.

Contribution

It provides an overview of cosmological evidence for non-baryonic dark matter and dark energy, integrating observational data with minimal theoretical frameworks.

Findings

Evidence for non-baryonic dark matter from astrophysical data

Support for inflationary theory from CMBR observations

Discussion of models incorporating dark matter and dark energy

Abstract

This lecture course covers cosmology from the particle physicist perspective. Therefore, the emphasis will be on the evidence for the new physics in cosmological and astrophysical data together with minimal theoretical frameworks needed to understand and appreciate the evidence. I review the case for non-baryonic dark matter and describe popular models which incorporate it. In parallel, the story of dark energy will be developed, which includes accelerated expansion of the Universe today, the Universe origin in the Big Bang, and support for the Inflationary theory in CMBR data.
