For our first Physics Colloquium of the new academic year, we will have a presentation to be given by Joonas Nättilä. In his colloquium, entitled Astrophysical turbulence: from stirring coffee to illuminating black holes, Joonas will give an overview on how supercomputer simulations can help shed new light on astrophysical turbulence.
Joonas Nättilä is a postdoctoral research scientist at Columbia University and a Flatiron Research Fellow at the Flatiron Institute’s Center for Computational Astrophysics in New York, USA. His research interests lie in high-energy astrophysics and plasma physics, focusing particularly on modelling the physics of neutron stars.
The event will be held on Friday 30.10.20 at 14:15, on the following University Zoom meeting:
Here is his abstract:
Turbulence – the seemingly chaotic flow of fluids and plasmas – is said to be one of the most important unsolved problems of contemporary physics and mathematics. It is a ubiquitous physical phenomenon operating in all kinds of environments, from mixing liquids in coffee cups to energizing astrophysical plasmas around black holes and neutron stars. In my talk, I will review some of the latest insights we have gained in understanding astrophysical turbulence from first principles by utilizing new state-of-the-art particle-in-cell supercomputer simulations.
In the spirit of our usual cocktail reception, we encourage all attendees to join us with a glass of your favourite tipple. Cheers!
