Ludwig M. Böss

I am a Postdoctoral Researcher at the University of Chicago, working with cosmological MHD simulations, and particle-in-cell (PIC) simulation of CR acceleration. My main interest lies in non-thermal processes in galaxy clusters: Cosmic Rays, Magnetic Fields and Turbulence.

I develop the Cosmic Ray model CRESCENDO for the cosmological Tree-SPH Code OpenGadget3.

Recently I joined the development team of entity, a particle-in-cell (PIC) code built for exa-scale computing.

Most of the time I run and analyze my own simulations for which I developed a number of open source Software tools.

I am also part of the Localization project where we study the local universe with state-of-the-art constrained initial conditions.

Before I went into Astrophysics I was a hobby musician, playing mainly progressive rock (you can listen to one album on Spotify!)
