Simultaneous single-pulse polarization observations of PSR B0950+08

It is known that the radio emission of pulsars is highly polarized. Orthogonal or non-orthogonal linear polarization position angle (PA) jumps has been observed in many pulsars. Simultaneous multifrequency studies of pulsar polarization ...After more than 50 years of the discovery of the first pulsar, the detailed physics of the emission process in a pulsar magnetosphere still remains unclear.The radio emission from pulsars is highly polarized. Simultaneous multifrequency ...

Unique emission properties in a long period CRAFT pulsar

Radio pulsars are well known for exceptionally regular emissions due to the stability of their rotation. However, large changes in the pulse shape and flux variations are detected at the individual pulses. A relatively long period pulsar...Radio pulsars are well known for exceptionally regular emissions due to the stability of their rotation.

Researchers investigate low emission mode in a pulsar

Mode changing is a manifestation of pulsar radiation variation. The study of mode changing is helpful to understand the emission characteristics and radiation mechanism of radio pulsars.Radio pulsars are known to exhibit significant emission variations in many different forms, such as the profile mode-changing. Study of these variations is important for unlocking the emission characteristics and the radiation mechanism ...
