![]() The official press release from the EHT Collaboration can be found here. SMA is one component of the Event Horizon Telescope, which combines multiple telescopes into a single globe-spanning observatory. ![]() The EHT project includes theoretical and simulation studies that are framing questions rooted at the black hole boundary that may soon be answered through observations. The latest results from the Event Horizon Telescope (EHT) Collaboration were published on Mar 24th 2021. Addition of key millimeter and submillimeter wavelength facilities at high altitude sites has now opened the possibility of imaging such features and sensing the dynamic evolution of black hole accretion. As the Event Horizon Telescope collected data for its remarkable new image of the Milky Way’s supermassive black hole, a legion of other telescopes including three NASA X-ray observatories in space was also watching. In both cases, the sizes match that of the predicted silhouette caused by the extreme lensing of light by the black hole. In anticipation of this, we describe a technique to measure the rotation rate, or pattern speed p, from movies using an autocorrelation technique. This technique of linking radio dishes across the globe to create an Earth-sized interferometer, has been used to measure the size of the emission regions of the two supermassive black holes with the largest apparent event horizons: SgrA* at the center of the Milky Way and M87 in the center of the Virgo A galaxy. The Event Horizon Telescope (EHT) has produced images of M87 and Sagittarius A, and will soon produce time sequences of images, or movies. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of. The EHT is an international collaboration that has formed to continue the steady long-term progress on improving the capability of Very Long Baseline Interferometry (VLBI) at short wavelengths in pursuit of this goal. Event Horizon Telescope (EHT) has produced images of the black hole in the galaxy M87 and in the center of our galaxy, and I will briefly review what we have learned from the images.
