Physics of Galaxy Formation

ACE 2026 · Summer Course

Physics of Galaxy Formation

From background cosmology and the growth of structure through cosmic reionization, the circumgalactic and intergalactic medium, high-redshift galaxies, gravitational lensing, and multi-wavelength probes of galaxy evolution. This course explores different aspects of galaxy physics across three weeks of lectures and hands-on tutorials.

This course offers a comprehensive introduction to the physics of galaxy formation, beginning with background cosmology and the linear growth of perturbations, and progressing through non-linear structure formation, galaxy formation, the circumgalactic medium, and the intergalactic medium. It then turns to cosmic reionization, high-redshift galaxy surveys, and finally to other multi-wavelength probes of galaxy evolution such as gravitational lensing, the Square Kilometre Array, black hole–galaxy co-evolution, HI 21-cm cosmology, and gravitational-wave observatories. Lectures are paired with hands-on tutorials in numerical and observational techniques.
