320 - The Event Horizon Telescope

Guest: Heino Falcke    Host: Markus Voelter    Shownoter: Kolja Dummann

A few months ago, a collaboration called the Event Horizon Telescope presented the first direct image of a black hole; or more specifically, of the radiation created by accelerated particles at its event horizon. The EHT is a Very Large Baseline Interferometer, in which radio telescopes all over the world are computationally connected to obtain resolutions that are not possible with one telescope. In the episode I chat with Heino Falcke, the chair of the EHT science committee, about the science, the telescope, what it took to get it going, and image reconstruction.
