An introduction to general relativity using the modern language of differential geometry

The writings and videos range from accessible discussions of ideas in the field and notes for students, through to technical working papers.
Easther and group members build visualisations to communicate concepts in physics, astronomy and cosmology.
Much of our research focusses on understanding non-linear processes in the universe, and we have developed tools to simulate these, and for cosmological data analyses.
