Black Hole team discovers path to Razor-sharp Black Hole Images

George Wong (UIUC) and Michael Johnson (CfA)The image of a black hole has a bright ring of emission surrounding a “shadow” cast by the black hole. This ring is composed of a stack of increasingly sharp subrings that correspond to the number of orbits that photons took around the black hole before reaching the observer.

A team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending. Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole...

A team of researchers from around the world is getting ready to create what might be the first image of a black hole. The project is the result of collaboration between teams manning radio receivers around the world and a team at MIT that will assemble the data from the other teams and hopefully create an image. The project has been ongoing for ~20 years as members have sought to piece together the Event Horizon Telescope (EHT).

Each of the 12 participating radio receiving teams will use equipment that has been installed for the project to record data received at a wavelength of 230GHz during April 5 through the 14th...
