FK5024

A 7-lecture series on introductory cosmology using Liddle's textbook as a reference. Part of Stockholm University's FK5024 (Particle and nuclear physics, astrophysics and cosmology). The latex notes and associated figures are available on github (link), but the lecture notes can also be found below. Lecture notes are largely based on notes passed on from Prof. Lars Bergström who taught this part of the course in 2018.

FK7007

Masters-level course on cosmology and astroparticle physics at Stockholm University. The lecture notes are largely based on notes from D. Baumann and E. Komatsu (look up their lecture notes, they're incredibly useful) as well as notes from previous course instructors.

####
Spring 2017

CMB: The cosmic microwave background (CMB), blackbody, recombination, reionization, homogeneity and isotropy, the Sachs-Wolfe Effect, CMB anisotropies

Large scale structure: Baryon acoustic oscillations, Newtonian perturbation theory, Fourier analysis of matter densities, power spectra, sound horizon, Gaussianity

Inflation: Particle horizons, flatness and horizon problem, cosmic inflation, inflaton dynamics, relation to cosmological observations

Other

Other teaching experience includes being a teaching assistant for University of Iceland undergraduate classes on linear algebra, partial differential equations, and experimental physics (see description in CV). My lecture notes from partial differential equations (in Icelandic) can be found here. I have also led a problem solving class in Modern Astrophysics for Princeton University science majors.
