Abstract:

Discovery of pulsars is one of main goals for large radio telescopes. The Five-hundred-meter Aperture Spherical radio Tetelscope (FAST) has the largest collecting area for radio waves, with an aperture of 300~m in diameter. Mounted with the 19-beam L-band receiver with a system temperature of about 20 K, it is the most sensitive radio telescope. The Galactic Plane Pulsar Snapshot (GPPS) survey was carefully designed to discover pulsars first within 5 degree of the Galactic latitudes from the Galactic plane and later to 10 degree. After very dedicated development and updating of data processing pipeline and a huge amount of extensive processing, we have discovered 550 pulsars, including 120 millisecond pulsars, 6 Fast Radio Bursts. In the mean time, we obtained the spectral line data which provide the deepest insights into the interstellar medium.

Biography:

JinLin Han (National Astronomical Observatories, Chinese Academy of Sciences) He obtained the Bachelor degree of Engineering in 1986 from Southeast University, and then went to Shanghai Observatory, Chinese Academy of Science to make his Master degree of Science. In 1989, he moved to Beijing Astronomical Observatory, Chinese Academy of Sciences to be a PhD student, and got PhD degree in 1993. After then he has been working in National Astronomical Observatories of China for about 30 years already. Prof. JinLin Han is world famous pioneer on the global magnetic field structure for the Milky Way. In last two decades, he spent a lot of energy to educate radio astronomy and pulsar astronomy in China. Recently he proposed and now is chairing the FAST Galactic Plane Pulsar Snapshot survey.
