Pulsar Scintillation: Overview and Some Recent Results

  • Yashwant Gupta


Radio signals from pulsars are significantly affected by scattering in the interstellar medium.A review of this phenomenon of pulsar scintillation forms the main objective of this paper. Thebasic concepts are described and some new results related to the following aspects are presented: (i)understanding of refractive scintillation effects and (ii) constraining the spectrum of electron densityfluctuations in the interstellar medium.
