On scattering of Giant Pulses from the Crab Pulsar: a Scattering Function

TL;DR

This study analyzes the scattering of giant pulses from the Crab pulsar using simultaneous dual-frequency observations, revealing that the scattering occurs at a thick screen rather than a thin one, which impacts understanding of pulsar signal propagation.

Contribution

It provides new evidence that scattering of Crab pulsar's giant pulses occurs at a thick screen, challenging previous thin-screen models.

Findings

Scattering occurs at a thick screen.

Simultaneous dual-frequency observations were conducted.

Implications for pulsar signal propagation models.

Abstract

Simultaneous dual-frequency observations of giant pulses from the Crab pulsar were performed at the frequencies of 61 and 111 MHz. It is shown that scattering of giant pulses from the Crab pulsar occurs at thick, and not at thin screen.
