Precision Determination of Scintillation Screen Parameters from Annual Modulation Measurement of Pulsar Scintillation Arc Curvature with the FAST Telescope
Researchers used annual modulation measurements of pulsar scintillation arc curvature from FAST telescope data to constrain distances, anisotropic scattering directions, and projected velocities of discrete interstellar screens. They identified 16 screens, successfully determining parameters for five using MCMC methods. This provides a detailed map of electron density fluctuations in the interstellar medium.
