Two years ago, astronomers acquired the first direct image of a black hole. An integrated observation mission of this object is now being linked to our understanding of this black hole and its turbulent situation.

Located at the core of the elliptical galaxy M87, this supermassive black hole carries a mass of 6.5 billion suns. In April 2019 Event Horizon Telescope (EHT) announced the collaboration a Direct image of this object, What an unparalleled achievement for astronomers.

Our perception of the M87 blackhole would be a big step in promoting the observation of wide multi-wavelengths of objects Details Which now appears in the Astrophysical Journal Letter. This huge expedition was held from April to March 2017 and involved 760 scientists from around 200 organizations around the world.

Juan Carlos Algba, an astronomer at the University of Malaya in Kuala Lumpur, Malaysia, told NASA’s JPL: “This incredible observation includes many of the world’s best telescopes. Press release. “This is a great example of astronomers from around the world working together to explore science.”

A total of 19 different observatories were used during the campaign, including the Hubble Space Telescope, the Lunar X-Ray Observatory, the Blue Gerails Swift Observatory and the Fermi Gamma-Ray Space Telescope. Together, these observations scan the entire electromagnetic spectrum by observing M ৮ black holes in radio waves, visible light, X-rays, and gamma rays.

“We knew that the first direct image of a black hole would be epoch-making,” explained Kazuhiro Hada, co-author of the study and astronomer at Japan’s National Astronomical Observatory, according to NASA. “But to get the most out of this remarkable picture, we need to know what can be done about the behavior of black holes by observing the electromagnetic spectrum.”

A companion Video Demonstrates the strength of this multi-wavelength approach. The video begins with the now-iconic image of the M78787 blackhole and is slowly zoomed in on the exp scale light years to reveal the whole phenomenon in context, and each observer is credited for his or her specific contribution. As well as external comparisons have been shown, scenes from black holes are reflected in radio waves, visible light, and X-rays. The final part of the video shows jets in black holes and gamma-rays as seen by the Fermi telescope.

High-velocity jets are an interesting feature of this and many other supermassive black holes. These planes are the result of the extraordinary gravitational forces involved and they move at the speed of light.

These jets produce a variety of intense light throughout the spectrum, and scientists are keen to study the complex patterns in them, as they are indicative of the black hole’s spin, energy output, and other properties. However, this is not a simple task, as these changes are constantly changing over time. The new study, through its integrated campaign, attempted to overcome this limitation and capture multi-wavelength snapshots of black holes using data captured by all these observations at about the same time. And in fact, it is now “the largest simultaneous observation mission ever with a supermassive black hole with jets,” NASA said.

The results could improve Einstein’s theory of general relativity and provide a better idea of ​​their possible connection to jets and cosmic rays.

“Particle acceleration is really central to understanding both particle acceleration, both EHT images and jets, with all their ‘colors,'” said Mark Markoff, co-author of the study and an astronomer at the University of Amsterdam. Carries the energy expressed by. Our results will help us calculate how much energy it carries and what impact blackhole jets will have on its environment.

More observation is needed, but the good news is that EHT has launched a new observation campaign this week. Excitingly, the new expansion will be even bigger, as it now includes the Arizona Kit Peak Telescope, France’s Northern Extended Millimeter Array (NOEMA) and the Greenland Telescope.

The results of the 2021 observation may not be available for some time, but we can’t wait to see the results, including how the M8787 blackhole has changed in the last four years.
