Galaxies and Cosmology L4. I: Ellipticals

In this lecture 4, we discuss properties of elliptical galaxies, dwarf galaxies, and the statistical galaxy population (of "normal" galaxies) at low redshifts. This first part is about elliptical galaxies; we handle their overall properties, surface brightness profiles, dynamics, the fundamental plane, and metallities and stellar contents. 0:00 Today's schedule 2:40 Elliptical overarching characteristics 16:20 Surface brightness 27:30 Dynamics (rotation vs anisotropic velocity dispersion) 38:20 The Fundamental Plane 47:35 Stellar population and metallcity #galaxies #cosmology #education #astronomy Link to Introduction to Galaxies and Cosmology playlist:    • Introduction to Galaxies and Cosmology   Please subscribe here if you want to stay posted on new videos:    / @jonsundqvist   Here's my group's research home page: https://fys.kuleuven.be/ster/research...
