NOIRLabįuzzy first photo of a black hole gets a sharp makeover The image of the M87 supermassive black hole originally published by the EHT collaboration in 2019 (left) and a new image generated by the PRIMO algorithm using the same data set (right).
To demonstrate the power of their new approach, which is called PRIMO, the team created a new, high-fidelity version of the iconic Event Horizon Telescope's image of the supermassive black hole at the center of Messier 87, a giant elliptical galaxy located 55 million light-years from Earth. A study detailing the findings published Tuesday in the Monthly Notices of the Royal Astronomical Society.Ī team of researchers, including an astronomer with NSF's NOIRLab, has developed a new machine-learning technique to enhance the fidelity and sharpness of radio interferometry images. The formation of a quasar can push the remaining gas out of a galaxy, depriving it of a key ingredient necessary for star formation, sometimes for billions of years. But when galaxies collide, all of that gas is driven directly toward the black hole, creating enough radiation to power a blindingly brilliant quasar. Many large galaxies host supermassive black holes at their centers, as well as copious amounts of gas, but that gas is usually largely out of reach of the hungry black hole at the galactic center. Their deep imaging observations revealed distorted structures in the outer regions of each galaxy that hosted a quasar. Just before the gas is gobbled up by the black holes, a tremendous amount of energy releases in the form of jets of radiation, creating a quasar.Īstronomers used the Isaac Newton Telescope, located on La Palma, which is part of the Canary Islands in Spain. When two galaxies merge, massive amounts of gas are pushed toward the supermassive black holes located at their centers. Messy eating habits might reveal elusive black hole
