Pulse Fluctuation Properties at 35 MHz

Original · EN

High time-resolution observations of pulsars were carried out at 35 MHz, using the Gauribidanur Radio Telescope (India), to study the spectra of intrinsic pulse-to-pulse fluctuations. Our sample consists of a few bright pulsars, each of which was observed for 1000 seconds so as to obtain long sequences of single-pulse data. The results, in terms of fluctuation features apparent at this radio frequency, are presented and compared with similar measurements at higher frequencies. We show that the picture of a circulating system of sub-beams emerges naturally from the behaviour apparent even at these long wavelengths.
