In a paper appearing in Nature Astronomy today, Michael Janssen and collaborators use the Event Horizon Telescope to detect a highly-collimated, asymmetrically edge-brightened jet at millimetre wavelengths in the active galaxy Centaurus A. These observations can tell us something about the internal structure of the jet and reveal something about the potential location of the supermassive black hole in Cen A.

In the video above you will see a discussion between Michael Janssen, the lead author of the study, Sera Markoff, Vice Chair of the Science Council of the Event Horizon Telescope collaboration and co-author of the paper, May Chiao, the chief editor of Nature Astronomy and myself. We tried hard to keep our discussion to one hour...and failed! We instead tackled a variety of topics relating to the paper itself, the Event Horizon Telescope (and when we might see an image of the black hole at the centre of our Galaxy), active galactic nuclei jets more generally and the community behind the Event Horizon Telescope collaboration.

Thank you to Michael and Sera for an extremely interesting and educational discussion. I am sure you will enjoy it as much as we did!
