Title: Calculating and observing the shadow of a black hole
In April 2019 the Event Horizon Telescope Collaboration presented an image of the shadow of the supermassive black hole at the centre of the galaxy M87. In this talk I discuss how the shadow of a Schwarzschild or Kerr black hole comes about, how its boundary curve can be analytically calculated, and how the image of the Event Horizon Telescope Collaboration was actually produced.
