Observation of Interplanetary Scintillation (IPS) provides an important and effective way to study the solar wind and the space weather. A series of IPS observations were conducted…
The radio signal of PSR B0950+08 is detected over the whole pulse phase
Zhengli Wang, Jiguang Lu, Jinchen Jiang +4
Pulsars are the "lighthouses" in the universe. Periodic pulses with the duty-cycle ~10% are detected when the radio beam of the rotating pulsar sweeps across the telescope. In this…
Repeating Fast Radio Burst: Coherent Circular Polarization By Bunches
