Detailed Study of Single Pulse Modulations in Pulsars

Several pulsars exhibit intriguing subpulse modulation properties -- distinct modes of drifting subpulses, bi-directional drifting, interesting combinations of pseudo-nulls, drift reversals, etc. Although there have been numerous single pulse studies, many important aspects are yet to be understood and several pulsars exhibiting interesting subpulse modulations are still waiting to be explored further. A systematic single pulse study of a carefully chosen sample of pulsars, over reasonably long-durations, has a great potential to provide a better understanding of the intriguing single pulse phenomena as well as to critically assess several physical models proposed to explain these phenomena. With this motivation, a systematic single pulse study of several pulsars is embarked upon. As a part of this systematic study, 24 hours of the telescope time is requested to conduct full-polarimetric observation of 4 carefully chosen pulsars at 430 MHz and L-band, using the Arecibo telescope.
