Using many different telescopes and instruments gave the team a more complete view of the structure of the supermassive black hole and its jet than was previously possible with EHT, and all of the telescopes were required to paint a full picture. These observations also revealed that the black hole's ring is 50% larger than previously believed. The observations represent the first time that the jet and the black hole have been imaged together, giving scientists new context into the compact radio core of M87. The jet was born from energy created by the magnetic fields surrounding the spinning core of the black hole and winds rising up from the black hole's accretion disk. In this artist's conception, the black hole's massive jet is seen rising up from the center of the black hole.
Scientists observing the compact radio core of M87 have discovered new details about the galaxy's supermassive black hole. If you think of it like a fire-breathing monster, before, we could see the dragon and the fire, but now we can see the dragon breathing the fire." This puts the ring in context-and it's bigger than we thought.
"With GMVA, including the premier instruments at NRAO and GBO, we're observing at a lower frequency so we're seeing more detail- and now we know there are more details to see."Įduardo Ros, an astronomer and the Scientific Coordinator for Very Long Baseline Interferometry (VLBI) at the Max Planck Institute for Radio Astronomy added, "We've seen the ring before, but now we see the jet. "M87 has been observed over many decades, and 100 years ago we knew the jet was there, but we couldn't place it in context," said Ru-Sen Lu, an astronomer at the Shanghai Astronomical Observatory, leader of a Max Planck Research Group at the Chinese Academy of Sciences, and lead author of the new paper. The image of its dense, dark core framed by an amorphous glowing ring made international headlines. It was the first black hole to be captured in an image, created by the Event Horizon Telescope (EHT) and made public in 2019. The SMBH at the center of the M87 galaxy is the most recognizable in the universe. The Global mm-VLBI Array (GMVA) united radio telescopes around the world to produce these new results, including the National Science Foundation's National Radio Astronomy Observatory (NRAO) and Green Bank Observatory (GBO), Atacama Large Millimeter/submillimeter Array (ALMA), Very Long Baseline Array (VLBA), and Green Bank Telescope (GBT).
