How to photograph a black hole – with Ziri Younsi

Video Description

Photographing a black hole used to be science fiction. But in April 2019 the Event Horizon Telescope made it reality - and Ziri Younsi was part of the team behind the breakthrough. Watch the Q&A with Ziri here: https://youtu.be/AwBRPrOBVTY See our playlist of talks about black holes here: https://www.youtube.com/playlist?list=PLbnrZHfNEDZx9TYta68iHw8XiH35kmxYR What are black holes? How are they created? Was the black hole in Interstellar accurate? And why did it take over a century between the discovery of black holes and confirmation of their existence? In this talk Ziri explores how we are now able to capture images of black holes using the Event Horizon Telescope, what we can learn from these images, and how these and future explorations will help advance our understanding of the origins of space, time, and the Universe itself. This talk was filmed at the Royal Institution on 25 February 2023.

After graduating from the University of Cambridge and subsequently UCL, Ziri began working within the Event Horizon Telescope (EHT) in 2014, first as a Humboldt Fellow at the University of Frankfurt and later as a Leverhulme Trust Fellow at UCL. His research program develops and performs supercomputer calculations of black holes, underpinning the EHT's interpretation of black hole images. He is a co-recipient of the 2020 Breakthrough Prize for Fundamental Physics and the Royal Astronomical Society's 2021 Group Achievement Award. In 2022 Ziri was elected to the EHT's Science Council, and is co-lead of the EHT's Gravitational Physics working group.
