Quasars, or quasars, are one of the brightest and most active types of gas-feeding supermassive black holes at the centers of distant galaxies. 3C 273 is the first quasar ever identified. It is located in the constellation Virgo.
An international group of scientists has published new observations of 3C 273. They recorded deeper and deeper parts of the prominent plasma glow in the quasar. Also includes observations of 3C 273 aircraft at the highest angular resolution to date, to obtain data on the interior of the aircraft, near Central black hole.
A global network of radio antennas, including the Global Millimeter VLBI Array (GMVA) and Chile’s Atacama Large Millimeter/submillimeter Array (ALMA), worked in close coordination to complete the pilot research. Coordinated observations were also made using the High Sensitivity Array to examine 3C 273 in various fields and determine the overall shape of the aircraft. The data used in this study was collected in 2017, just as the Event Horizon Telescope (EHT) observations were being produced. The first image of a black hole.
Scientists have got the first look at the deepest region of the jet stream in A quasarswhere collimation occurs, thanks to images of the 3C 273 plane. Scientists also found that at very large distances, the angle Plasma streams emit from the black hole ever tighter. The extremely narrow passage of the plane extends far beyond the area in which it is located gravity of the black hole not expired.
Kazunori Akiyama, a researcher at MIT’s Haystack Observatory and project leader, said: “It’s amazing to see a strong current form slowly over such a long distance Very active quasar. It has also been detected nearby in a much fainter and less energetic supermassive black hole. The findings raise new questions: How does jet collimation occur consistently across various black hole systems? “
Lynn Matthews, principal investigator at MIT’s Hastack Observatory and commissioning scientist told APP: “The ability to use ALMA as part of a global VLBI network is a complete game changer for black hole science. This allowed us to get the first-ever picture of a supermassive black hole, and now it’s helping us see something startlingly new for the first time. details on how black holes steer their jets”. .
Keiichi Asada, Associate Research Fellow at Academia Sinica, Institute of Astronomy and Astrophysics (ASIAA) in Taiwan, he saidAnd ‘This discovery sheds light on collimation in quasar jets. The EHT’s sharp eyes will allow them to reach similar areas in even more distant quasar jets. We hope to make progress on our new ‘homework’ of this study, which will allow us finally answering the problem. It’s been a hundred years on how planes crash.”
