Thanks to CTOnews.com netizen Real_ for the clue delivery! CTOnews.com, August 19 (Xinhua)-- A new form of pulsar radiation has been detected by a Chinese scientific team using the "Chinese Sky Eye" FAST: a group of extremely weak narrow pulses were detected from a pulsar originally thought to be "extinguished", according to the Xinhua News Agency on Friday night.

The study, conducted by Han Jinlin, a researcher at the National Astronomical Observatory of the Chinese Academy of Sciences, is of great scientific significance to reveal the extreme physical environment of the pulsar magnetosphere, according to a screenshot report by ▲ Xinhua News Agency. In addition, the relevant results were published in the international academic journal Natural Astronomy on August 18.

According to reports, pulsars radiate radio signals periodically when they are rotating, and some old pulsars often "extinguish" radiation in certain cycles-a phenomenon known as "pulse zero suppression". Because the structure and physical properties of the magnetosphere can not be detected after the radiation is "extinguished", the physical mechanism of this phenomenon has been difficult to determine.

When the research team observed a known pulsar B2111Y46, they found that there were still short pulses in its "pulse zero suppression" state-- weak, narrow and sporadic pulses. Subsequently, the scientific research team carried out a 2-hour verification observation, and finally detected more than 100 short pulses. Han Jinlin pointed out that the discovery benefited from the ultra-high sensitivity of the "Chinese Sky Eye", and the new form of pulsar radiation detected "opened a new window" for the study of pulsar radiation-related problems.

CTOnews.com previously reported that "Chinese Sky Eye" has entered a period of explosive results, and has released a number of important achievements this year, including the discovery of a pulsar binary system with an orbital period of only 53 minutes, and the detection of key evidence of the existence of Nahertz gravitational waves, which has continued to maintain China's international leading position in low-frequency radio astronomy.

By late July this year, the 500m aperture spherical Radio Telescope (FAST), the world's largest and most sensitive single-aperture radio telescope built by China, had discovered more than 800 new pulsars, which is more than three times the total number of pulsars found by other telescopes in the world at the same time.
