The First Detection of Coherent Emission from Radio Pulsars

The statistical properties of the radio emission from the pulsars B0823]26, B0950]08, B1133]16, and B1937]21 are studied using high time resolution observations,taken at the Arecibo Observatory,in Puerto Rico. Temporally,coherent,non-Gaussian emission has been detected in three of the four observed,objects. This is the —rst time such a phenomenon,has been,observed. The results have been interpreted using a generalized shot noise model, and various basic physical quantities pertaining to the magnetospheric,plasma,have been estimated.
