Career and research

Hernquist's research involves the dynamics of galaxies and the effect of a merger driven model for galaxy evolution. He is a world expert in simulating mergers of galaxies to demonstrate the expected appearance and morphology of the resulting body. He defined the "Hernquist Profile", which is an analytic expression for the distribution of dark matter in galaxies.[5] Hernquist's research is largely computational with one of the world's largest supercomputers accessible for his research.[6]

Awards

Hernquist was awarded the 2020 Gruber Prize in Cosmology jointly with Volker Springel, who together have made computer simulations "an indispensable tool for cosmologists, allowing them to test theories and locate fertile areas for further research."[7]

gollark: Stuff like the proof of Fermat's last theorem required connecting together a bunch of disconnected-looking areas of maths in very clever ways. There's more to that than just "practice", by most definitions of practice.
gollark: If you want to solve "the most difficult solvable equation in the world" you're probably going to have to come up with a lot of new techniques.
gollark: Practising stuff will make you better at what you're already able to do mostly.
gollark: No you won't.
gollark: Well, some maths at school etc. is like that, but it isn't real maths™.
