Italian researchers have released a statement on the M87 study
– A new image of the first black hole ever recorded appears to confirm Albert Einstein’s theory of general relativity.
The image of M87* was obtained by the international scientific collaboration Event Horizon Telescope, which includes the national institutes of Astrophysics (Inaf) and Nuclear Physics of Italy (Infn), as well as the universities of Cagliari and Federico II of Naples
The new image shows only a slight change in brightness and the result was published in the journal Astronomy & Astrophysics.
The record is the result of observations made in April 2018, a year after those made in April 2017 and published in 2019, with the first image of a black hole.
The updated instruments, the Italian researchers said in a joint statement, “offer an independent view of the first observations of 2017.”
At a distance of 55 million light-years from Earth, the black hole M87* is the core of the giant galaxy Messier 87, and its new image shows a bright ring the same size as the one observed in 2017, surrounding a deep central depression , the so-called ?shadow of the black hole? predicted by the theory of general relativity.
The only difference is in the shift of the ring’s brightness peak, in line with current theories on the variability of turbulent material around black holes.
“We used different imaging algorithms and modeling techniques to obtain this new independent reconstruction of M87*”, highlighted Rocco Lico, from Inaf.
“This result represents the first attempt to explore the many years of additional data we have collected,” added Mariafelicia De Laurentis, a researcher at the Infn.
