Aim of the course: This course intends to give the students a modern and up-to-date introduction to the science and experimental techniques relating to the Cosmic Microwave Background (CMB). No prior knowledge of cosmology is assumed; rather, the course introduces the necessary concepts in the class, and partly depends on the mandatory cosmology course that is taught in parallel. The aim is to make the students interested in the vast field of CMB research, which continues to be one of the richest sources of information about our Universe.
|
|
Requirements: Some basic knowledge of electrodynamics and thermal physics, and some experience with Python programming. No prior course-work on cosmology is necessary.
|
|
Contents of the course: Roughly 13 lectures, covering the four main topics of (i) CMB thermal spectrum, (ii) CMB temperature anisotropies and their cosmological significance, (iii) CMB polarization and the search for primordial gravitational waves, and (iv) CMB foregrounds and component separation techniques. There will be weekly exercise classes, some of which involve simple programming and plotting.
