[under the leadership of academician ye shuhua, the shanghai observatory established my country's first 25-meter-diameter radio telescope, which opened the way for the development of my country's radio interferometry technology. ]

supermassive black holes at the centers of active galaxies are among the most destructive and mysterious objects in the universe. their gravity is huge, and they "eat" a large amount of matter through the accretion disk, and at the same time "spit" the matter out thousands of light-years away at a high speed close to the speed of light. however, what is the energy transfer mechanism between supermassive black holes, accretion disks and jets? this is a problem that has puzzled physicists and astronomers for more than a century.

lu rushen, a researcher at the shanghai observatory of the chinese academy of sciences and leader of the "high-resolution radio astrophysics" research group, and his colleagues are researchers exploring these problems.

lu rushen, who returned to china to join the shanghai observatory in 2018, in addition to successfully capturing mankind's first black hole photo, polarization image and the first photo of the black hole in the center of the milky way at the center of the m87 galaxy with his collaborators in 2019, 2021 and 2022, last year in 4 in march, he also led an international team to take the first panoramic view of the m87 black hole, which for the first time showed the connection between the accretion flow near the central supermassive black hole and the origin of the jet. the relevant results were published in the journal nature.

"at that time, there was a lot of accumulation in the field of black hole imaging research internationally, but the domestic foundation was still relatively weak. when i returned to china, i also felt that i should be able to do something else in this field." in a recent exclusive interview with china business news, lu rushen said.

in addition to taking photos of the m87 black hole and the black hole at the center of the milky way, lu rushen and his colleagues are also planning to take photos of other black holes, as well as "black hole color photos" and black hole "movies." "in the black hole photos we see, will the structure around it change over time? will it change with the (observation) frequency? sometimes for the convenience of introduction, we will also use color to describe it. this color represents the observation. frequency. this is our main research direction in the future and what we are doing.”
