Supermasive Black hole M87 focuses sharply and sharply on the heart of the galaxy.
Two years ago, astronomers with the event Horizon Telescope (EHD) program Released pictures of that black holeIt is 55 million light years away from Earth and is about 6.5 billion suns away. Those photos are historically significant – the first live footage of a black hole ever captured by mankind.
In the spring of 2017, while the EHD team was collecting some data that would produce epic images, nearly 20 powerful telescopes on the ground and in space were also exploring the M87 black hole.
A new study describes this vast and powerful data set, which includes observations over a wide range of wavelengths collected by NASA Hubble Space Telescope, Chandra X-ray Laboratory, The Neil Kehrals Swift Labs, Nuclear Spectroscopic Telescope Series (NUSTAR) and Fermi gamma-ray space telescope, As well as many other purposes.
“We know that the first live image of a black hole will be innovative,” said Kasuhiro Hata, co-author of the National Astronomical Laboratory of Japan. Said in a statement. “But to use this remarkable image, we need to know everything we can about the behavior of the black hole at that time by observing the entire electromagnetic spectrum.”
That behavior includes jet planes, or beams of radiation, and particles moving rapidly outward from the black hole of the M87. Astronomers believe that such jets are the source of the highest energy Cosmic rays, Particles magnifying through the universe at the speed of light.
The study team members said the new data set collects the results of the most intense simultaneous surveillance campaign ever carried out in a black hole with jets. Therefore, plumbing will provide important insights into jet dynamics and the origin of cosmic rays.
“Understanding particle acceleration is really important in understanding both EHD film and jets in all their colors,” said Sera Markoff, co-author of Astronomy at the University of Amsterdam.
“These jets are able to carry the energy emitted by the black hole to larger scales than the host galaxy, which is like a large electric pole,” Markoff said. “Our results will help calculate the amount of energy carried and the impact of jet planes on the black hole in its environment.”
EHD, which connects radio telescopes around the world, is developing an earth-sized virtual instrument that is scheduled to observe the M87 black hole again this week after a gap of two years. The project collects data only during a short window in the Northern Hemisphere spring each year, and the weather is fine at its various monitoring sites. Technical issues halted the 2019 campaign, which was halted by a corona virus infection last year.
As in previous years, the new EHD campaign will include observations of the amazing black hole at the center of our own Milky Way galaxy, a 4.3 million solar-mass object. Sagittarius A *. The new data will be even more revealing as the Greenland telescope, the Kid Peak 12-meter telescope in Arizona and the expanded millimeter range in the north of France – EHD recently added three major objectives to its network.
“By releasing this data, along with re-monitoring and enhanced EHT, we know that many exciting new results are on the horizon,” said Mislav Palokovic, a research associate professor at Yale University.
A new study collecting the work of 760 scientists and engineers from nearly 200 companies around the world was released online Wednesday (April 14). Letters from the Journal of Astronomy.
