The shape of pulsar radio beams
Using all available multi-component radio pulse profiles for pulsars with medium to long periods and good polarisation data, we have constructed a two-dimensional image of the mean radio beamshape. This shows a peak near the centre of the beam but is otherwise relatively uniform with only mild enhancements in a few regions. This result supports the patchy-beam model for emission beams in which ...
متن کاملStructure of pulsar beams : conal versus patchy
Structure of mean pulsar radiation patterns is discussed within the nested-cones and patchy beam models. Observational predictions of both these models are analyzed and compared with available data on pulsar waveforms. It is argued that observational properties of pulsar waveforms are highly consistent with the nestedcone model and, in general, inconsistent with the patchy beam model.
متن کاملRevisiting the shape of pulsar beams
Characterizing the shape and evolution of pulsar radio emission beams is important for understanding the observed emission. The various attempts by earlier workers investigating beam shapes have resulted in widely different conclusions. Using a carefully selected subset of the recently published multifrequency polarimetry observations of 300 radio pulsars (Gould & Lyne, 1998), we attempt to mod...

متن کاملA Further Study of Relative Longitude Shift of Pulsar Beams
It is of great important to study pulsar beam shapes if we are concerned with emission theories and pulsar birth rate. Both observations[9, 16] and/or the ICS model[10] show that different emission components are emitted from different heights. The relative longitude phase shifts due to different heights of emission components and to the toroidal velocity of electron are considered in this pape...
