The Multiple Images of the Plasma Lensing FRB
Y-B. Wang, Z-G. Wen, R. Yuen +3
We investigate the formation of multiple images as the radio signals from fast radio bursts (FRBs) pass through the plane of a plasma clump. The exponential model for the plasma cl…
Giant micropulse emission in the Vela pulsar at C band
J. L. Chen, Z. G. Wen, L. F. Hao +11
We present here the analysis of giant micropulses from the Vela pulsar. A total of 4187 giant micropulses with peak flux density 2.5 Jy were detected during almost 4 hours of ob…
Pulsar Electrodynamics: an unsolved problem

Visibility of pulsar emission: motion of the visible point
R. Yuen, D. B. Melrose
A standard model for the visibility of pulsar radio emission is based on the assumption that the emission is confined to a narrow cone about the tangent to a dipolar field line. Th…
