The frequency dependence of scattering imprints on pulsar observations

Abstract:

Observations of pulsars across the radio spectrum are revealing a dependence of the characteristic scattering time (τ ) on frequency, which is more complex than the simple power law with a theoretically predicted power-law index. In this paper, we investigate these effects using simulated pulsar data at frequencies below 300 MHz.We investigate different scattering mechanisms, namely isotropic and anisotropic scattering, by thin screens along the line of sight, and the particular frequency-dep...
