Studying the Universe with Light

This lecture provides an overview of the physical concepts used in astrophysics to analyze observations taken by telescopes, aiming to understand the physical mechanisms behind light radiation from celestial bodies and their motion. Spanning from our solar system to the universe, the course emphasizes the links between theoretical concepts and observations, presented by the instructor, Fredric Corbin, a researcher at the Laboratory of Astrophysics at EPFL. The course is designed for second-year physics students and covers topics from stellar formation to galaxy evolution, requiring minimal prerequisites in physics.
