Dr. Alex Richings’ research uses numerical simulations to explore how galaxies form and evolve. He is particularly interested in the role that the chemistry of interstellar gas plays in galaxy formation. The chemical abundances of ions and molecules determine how quickly the interstellar gas can cool. By modeling chemical processes in galaxy simulations, we can also make predictions for observable emission and absorption lines from particular ions and molecules, which helps us to compare our models to observations, and enables us to probe the physical processes behind these observations.
Dr. Richings was the CIERA Lindheimer Postdoctoral Fellow from 2016 – 2018. He moved to the role of Junior Research Fellow, Durham University, UK following his fellowship.
