Tim Dietrich


Hi,
I am Tim Dietrich (CV) and currently employed as a Junior scientist at the Albert Einstein Institute. I am working in the field of Numerical Relativity, in particular I am studying the merger of binary neutron stars.
Over the last years I have performed several hundred simulations, which will be made publicly available soon. I have also developed a model to compute kilonovae lightcurves, and produced different animations. If you have any questions about my work, please contact me.
