An international team anchored by the Event Horizon Telescope (EHT) Collaboration has now imaged the heart of the nearby radio galaxy Centaurus A in unprecedented detail.
This work, led by Michael Janssen from the Max Planck Institute for Radio Astronomy in Bonn and Radboud University Nijmegen is published in Nature Astronomy on 19 July 2021.
