You must have noticed the spectacular image shown above. The purple haze shows the radio emission of relativistic jets belonging to the nearby galaxy Centaurus A. Here the object is projected in its actual size as it would be seen on the sky if its light were visible to the human eye. This stunning example […]

Throughout this past year, I have been working in Sera’s group, alongside Matthew Liska (PhD of Michiel van der Klis), on analyzing the largest black-hole (BH) accretion simulations ever performed. In collaboration with Alexander Tchekhovskoy (Northwestern University) and Adam Ingram, we studied tilted accretion of magnetized matter onto a rapidly spinning BH, and the resulting

Ever watched a black hole launch matter into space? Me neither, but this simulation comes pretty close! The video below is a visualization of a high resolution 2D simulation of the accretion disk of a black hole, made by me using the state-of-the-art GRMHD* code called HAMR** on a single GPU. The simulations are partly

Hi, My name is Casper. Besides the usual astrophysics conundrums I’m also interested in how the brain works. Neuroscience is a bit like astrophysics in that we are pretty good in imaging stuff but still limited in our understanding. To illustrate this, here is a picture of my own brain made with a technique called
