China's Daocheng Solar Radio Telescope (DSRT), the largest of its kind in the world, has successfully identified the pulsar flicker in its first pulsar detection experiment based on radio image sequence, said the National Space Science Center (NSSC) under Chinese Academy of Sciences on Thursday.
The homegrown solar radio imaging telescope is now undergoing system debugging.
Researchers from the Key Laboratory of Solar Activity and Space Weather of the NSSC on Tuesday carried out the pulsar observation using 146 antennas that had been integrated. The team successfully obtained a continuous radio image sequence and identified the flicker of the pulsar coded J0332+5434.
The experiment has verified the DSRT's ability to detect pulsars, which will lay a foundation for expanding the application of the DSRT, said the NSSC.
Located on the edge of the Qinghai-Tibetan Plateau in southwest China's Sichuan Province, the DSRT consists of 313 six-meter-wide parabolic antennas encircling a 100-meters-high calibration tower in the center.
The 313 sun-gazers in collaboration form a huge, virtual telescope working at the frequency range from 150 to 450 megahertz to achieve high-precision imaging of solar events.
It has been equipped with high-quality solar monitoring capabilities, which has acquired a large amount of solar activity images and spectral data since March 2021.
Construction started in 2019, and hardware integration work was completed last year. It is expected to enter trial operation in June, according to the NSSC.
