On September 21st, 2022 I delivered my inaugural lecture ("oratie") as professor of Observational High-Energy Astrophysics at the Aula of the University of Amsterdam.

Thanks to everyone who came in person, watched online from afar, or sent good wishes. The lecture was recorded and is viewable here.
