Galaxies: Bejewelled Island Universes
Galaxies are where most of astrophysics takes place. In this talk, I will summarize what we know about galaxies and how we came to know this. I will also touch on how galaxies were used to discover the existence of dark matter and the expansion of the Universe, and how both discoveries laid the foundation for our current understanding of how galaxies formed and evolved to the bejewelled island universes we see today.
