Chinese Astronomers Make Groundbreaking Discovery in Studying Black Hole Jets
Chinese astronomers, leading an international research team, have made a groundbreaking discovery in studying the dynamic features of relativistic jets of a black hole. The team’s focus was on GRS 1915+105, a fast-spinning black-hole X-ray binary that is well-known for its relativistic jet.
To conduct their study, the researchers utilized China’s FAST (Five-hundred-meter Aperture Spherical Radio Telescope), the world’s largest single-dish radio telescope. By observing the radio continuous spectrum light change and polarization of GRS 1915+105, they were able to gather crucial data.
The team’s use of FAST’s high sampling and sensitivity paid off when they made a significant detection. In January 2021 and again in June 2022, they observed two instances of transient periodic oscillations. These oscillations, known as quasiperiodic oscillations, are noteworthy as they are the first sub-second low-frequency radio quasiperiodic oscillations ever observed in a microquasar.
The implications of this discovery are immense. This exciting finding directly links the phenomenon of quasiperiodic oscillations to relativistic jets, shedding new light on the dynamic processes of super-dense celestial bodies. It opens up fresh avenues for radio observation and theoretical research of black holes.
The team’s research has great scientific significance, as it deepens our understanding of the origin and dynamic process of relativistic radio jets of super-dense celestial bodies. By studying GRS 1915+105 and its relativistic jet, this breakthrough brings us closer to unraveling the mysteries surrounding black holes.
This ground-breaking study has been welcomed by the scientific community, as it contributes to our knowledge of the universe’s most perplexing phenomena. The Chinese astronomers leading the research team have received widespread recognition for their remarkable achievement.
Moving forward, the team plans to further explore the intricate behaviors and properties of black hole jets using advanced observational techniques. Their invaluable contributions in this field of research are expected to inspire and shape future studies conducted by scientists worldwide.
In conclusion, Chinese astronomers, in collaboration with an international research team, have made a groundbreaking discovery in studying relativistic jets of a black hole. Using the world’s largest single-dish radio telescope, they detected the first sub-second low-frequency radio quasiperiodic oscillations in a microquasar, directly linking this phenomenon to relativistic jets. This discovery paves the way for future research and observation of black holes and enhances our understanding of these enigmatic cosmic entities.
