Scientists have used a global array of radio telescopes to capture a new wide-angle image of the famous M87 black hole.
. The paper describes the team’s use of a longer wavelength than the EHT team, 3.5 mm instead of 1.3 mm, to better show the jet of energy emerging from near the black hole.
“This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. This thin disc of rotating material consists of the leftovers of a Sun-like star which was ripped apart by the tidal forces of the black hole. The black hole is labelled, showing the anatomy of this fascinating object.” | Credits: ESO
Compared to the original EHT image, the ring observed by Lu’s team is roughly 50 percent larger. The GMVA network comprises 14 radio-telescopes in Europe and North America, plus two more facilities, the Greenland Telescope and ALMA.
