"China Sky Eye" chief engineer: will use Fast to solve the core technical problems in the field of radio astronomy

From August 26th to 27th, seconds Jiqingke · approaching China Tianyan Innovation Forum was held in Pingtang, Guizhou. Jiang Peng, chief engineer of the 500 -meter -diameter spherical radio telescope (referred to as "FAST"), said at the forum that when stable operation and improvement of performance, the future sky patrol efficiency of FAST technical problem.

FAST, known as the "China Eye", was opened in Pingtang, Guizhou on September 25, 2016. It is currently the world's largest and most sensitive single -caliber radio telescope. Data show that the annual operator has reached 6,200 hours since the acceptance of Fast. Its excellent performance and stable operation have spawned a series of scientific achievements with international influence.

Jiang Peng said that due to the late start of China's radical astronomical field, the core key issues in the field of radical astronomy are mainly in terms of receiving machines. In the future, the FAST platform will be used in the future, and the efforts of the technology research and development team will strive to solve core technologies within 5 years to solve core technologies within 5 years. Problem, develop advanced receiving machine systems.

As of now, Fast has more than 660 pulse stars, and has more than 100 high -level papers based on Fast observation data. FAST's high -sensitivity observation also discovered the changes in repeated fast radio violence and polarization angle, revealing that the rapid radio violence comes from the magnetic star that comes from the distant universe.

It is understood that FAST has developed the development of pulse star timing system and advanced receiving machine system development. In the future, FAST will also penetrate the scientific research of pulse star search, fast radio violence, neutral hydrogen inspection, interstellar formation, and gravitational wave detection.
