The Event Horizon Telescope is an Earth-sized network of millimeter-wavelength telescopes that together comprise the highest resolution imaging instrument in the history of astronomy, sufficient to image the event horizons of known astronomical black holes. Over the past decade pathfinder experiments have provided the first direct evidence of horizon-scale structures about the black holes at the centre of the Milky Way and the giant elliptical galaxy M87. Since April, 2017, the full EHT has started operations, and will transform our understanding of the nature of black holes and the processes underlying the growth of black holes, including their inordinate impact on their host galaxies and galaxy clusters. Broderick leads the EHT Initiative at PI, is a key organizing member of the EHT collaboration and currently serves on the EHT Board.
