Title: "About that First Look at a Black Hole"
Abstract: On April 10, 2019, the Event Horizon Telescope Collaboration caught the world's attention when it revealed an image of the supermassive black hole at the center of the M87 galaxy. In this talk I will share some of that experience, and the details of the technique involved (VLBI: Very Long Baseline Interferometry) as well as the challenges of working with an Earth-sized instrument operating at the highest practical radio frequencies. The results that follow from the image can then be placed within the more general context of black hole and active galactic nuclei (AGN) science--what we have learned and what we have not yet learned--as well as the prospects for more results to come.
