As you are reading this text you are most likely using a device that contains a collection of central processing units (CPUs) running processes and threads, and potentially even uses a graphics processing unit (GPU) to render it nicely for you. Besides all of us using these “things” every day in computers, tablets, and smartphones, […]

In my earlier blog post (part 1), I posed the question of how some of the most energetic gamma-rays observed by the LHAASO and HAWC observatories can be created. In order to understand their origin, I drew an intuitive picture of how a photon can scatter off an electron at rest, usually called Compton scattering.

Did you know that light can bounce off a charged particle like an electron? And that this interaction can lead to some of the highest-energy gamma-ray radiation that we have ever observed in the universe? In this double blog post, I will build up an intuitive and visual understanding of how this quantum billiards between

With the advent of the Christmas time, it is common to put yourself a nice candle in the living room (or sometimes even four or more). It is particularly nice to enjoy the warm and dim orange light, softly flickering and creating a cozy atmosphere. As an astrophysicist researching the light emission from outflows moving
