The elusive celestial objects, estimated to be between three and 10 times the mass of our sun, are created when exploding stars collapse. Each flare is brighter than the last, creating a signature that might help astronomers find them.”Īstrophysicists are still trying to prove if intermediate-mass black holes exist in the first place.
After each passage, they lose more mass, causing a flair of light as (it’s) ripped apart. We found that stars undergo multiple passages before being ejected. “So, instead, we have to look at the interactions between black holes and their environments. She is also a member of the university’s Center for Interdisciplinary Exploration and Research in Astrophysics. “We obviously cannot observe black holes directly because they don’t emit light,” said lead study author Fulya Kıroğlu, a doctoral student of astrophysics at Northwestern University’s Weinberg College of Arts and Sciences in Evanston, Illinois, in a statement. NOIRLabįuzzy first photo of a black hole gets a sharp makeoverĪ study describing the modeling analysis has been accepted for publication in The Astrophysical Journal, and the findings will be presented Tuesday at the American Physical Society’s April meeting. 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 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.
