Imaging Black Holes with the Event Horizon Telescope
The Event Horizon Telescope (EHT) is a global submillimeter-wavelength very long baseline array that produces the highest angular resolution images of black holes. The EHT Collaboration has produced images of two black holes, the supermassive black hole in the elliptical galaxy M87 and the Galactic Center black hole, Sgr A*.
In this talk, I will describe the techniques and technology behind these measurements, give updates on the latest results, and plans for future observations. Images of both sources have a ring-like morphology consistent with predictions of general relativity and the Kerr metric.
The event flyer is available here.
