The well-known first picture of the supermassive black hole on the coronary heart of our galaxy might not be correct, a brand new research has claimed.
The picture – initially printed in 2022, after years of intense work by a world staff known as the Event Horizon Telescope (EHT) collaboration – was a shocking perception into the swirling mass that sits on the coronary heart of the Milky Way galaxy.
The picture famously confirmed a doughnut-shaped ring with a spherical orange form and a darkish hole in the center. The darkish area on the centre is the black hole itself, and the orange exhibits the fuel that has been heated to intense temperatures by the highly effective gravitational forces round it.
But a brand new research means that form is mistaken. In reality, the disk of accreted materials across the black hole could be longer, in accordance with the brand new research led by the National Astronomical Observatory of Japan.
The research flies in the face of huge quantities of research each to assemble after which confirm the information used to create the unique picture.
Researchers say nevertheless that errors in the method might have led the information to be wrongly analysed. They made the declare after wanting on the information, initially gathered in 2017, that was used to create the picture.
“Our image is slightly elongated in the east-west direction, and the eastern half is brighter than the western half,” stated Miyoshi Makoto, from the NAOJ.
“We think this appearance means the accretion disk surrounding the black hole is rotating at about 60 per cent of the speed of light.
“Why, then, did the ring-like image emerge? Well, no telescope can capture an astronomical image perfectly.
“We hypothesise that the ring image resulted from errors during EHT’s imaging analysis and that part of it was an artefact, rather than the actual astronomical structure.”
A paper describing the claims, ‘An independent hybrid imaging of Sgr A* from the data in EHT 2017 observations’, is printed in the journal Monthly Notices of the Royal Astronomical Society.
