M87: The Ring in Polarised Light
The Event Horizon Telescope (EHT) is a global very long baseline interferometry (VLBI) network imaging supermassive black holes at horizon scales at 1.3-mm wavelength. I will present the recently published polarised-light images of the supermassive black hole at the heart of the M87 galaxy. I will discuss how the polarimetric data were analysed and what inferences can be drawn from these results about the magnetic fields near the black hole. Finally, I will consider some open questions and what the future holds for high-resolution black hole observations.
