Pulsars are rapidly rotating, highly magnetized neutron stars which emit beams of electromagnetic radiations from their poles, acting like cosmic lighthouses. Most of them have a surprisingly stable period of revolution. Studying these pulsars and variations in their radiation while it reaches earth, can reveal a lot of information about the pulsar itself, its local surrounding, the Interstellar Medium and much more. A few properties of pulsars like the period, flux density, Dispersion Measure, distance, modulation index, Pulse broadening due to interstellar scattering, etc. have been studied for a couple of pulsars observed using the Ooty Radio Telescope. The calculations and results are discussed followed by a small description of the application of studying pulsars and other radio sources in deriving additional inferences like solar wind velocity and understanding mysterious phenomena like Gravitational Waves. Some preliminary analyses will be presented which have been done during “Camp for Hands-on Experience in Radio Astronomy” during June 2015 at RAC, Ooty.
