Galaxies and Cosmology 2023
Here above is the link of 🅶🅰🅻🅰🆇🅸🅴🆂 🅰🅽🅳 🅲🅾🆂🅼🅾🅻🅾🅶🆈 2023, Winter Edition, whose material is also at the dedicated page on S.George Djorgovski's on Caltech site.
This I would take after finishing The Evolving Universe class on Coursera.
You also have access to an earlier version (very similar, but not identical).
Thanks to Professor Djorgovski for sharing!
