Quasars, or substellar objects, are one of the brightest and most active types of supermassive black holes that absorb gas at the center of distant galaxies. 3C 273 is the first confirmed quasar. It is in the constellation of Virgo.
An international group of scientists has released new observations of 3C 273. They observed the quasar’s prominent plasma in the innermost and deepest part of his jet. Also included are his observations of the 3C 273 jet at the highest angular resolution to date, capturing data on the innermost part of the jet. central black hole.
A global network of radio antennas, including the Global Millimeter Wave VLBI Array (GMVA) and Chile’s Atacama Large Millimeter/Submillimeter Wave Array (ALMA), worked closely together to achieve groundbreaking research. Coordinated observations were also made using a sensitive array to probe 3C 273 at various scales and determine the overall shape of the jet. The data used in this study were collected in 2017, generated by Event Horizon Telescope (EHT) observations. first picture of black hole.
Scientists have explored the deepest part of a jet plane for the first time ever. quasar, thanks to the image of the 3C 273 jet collimation. Scientists have also found that over very long distances, Stream of plasma from a black hole Toned. The constriction of the jet extends unusually far. black hole gravity is valid.
Kazunori Akiyama, research scientist and project leader at the Massachusetts Institute of Technology Haystack Observatory. “It is impressive that the shape of the powerful flow slowly takes shape over a long distance. very active quasarIt has also been found near much fainter and less active supermassive black holes. This result raises a new question: How is jet collimation consistent across such diverse black hole systems?”
Lynn Matthews, principal research scientist at the Massachusetts Institute of Technology Haystack Observatory and APP contract scientist, said: “The availability of ALMA as part of the global VLBI network is a complete game-changer for black hole science. It helps us see incredible new details for the first time about how we power our jets.”
Keiichi Asada, associate researcher at the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) in Taiwan, said: Said, “This discovery sheds new light on jet collimation in quasar jets. EHT’s sharper eyes allow access to similar regions of more distant quasar jets. New ‘homework’ from this study.” and hopefully be able to finally answer the 100-year-old question of how to collimate a jet. ”
