I Circular polarization and linear polarization of pulsars

AI Thread Summary
The discussion centers on the polarization characteristics of pulsar radiation, questioning whether circular or linear polarization predominates. Research indicates that polarization is complex and influenced more by propagation effects than by source characteristics. Most pulsar emissions exhibit elliptical polarization, suggesting a mix of both circular and linear components. The distinction between spectrally integrated and spectrally resolved observations is crucial, as certain polarization types can alter light frequency in ways that may obscure true polarization measurements. Understanding these factors is essential for accurately interpreting pulsar radiation.

Is there more circular polarization or linear polarization in the radiation flux of pulsars?

Have any papers discussed this issue?
 
Astronomy news on Phys.org
Many papers consider polarization from radio pulsars (for example, https://www.cambridge.org/core/jour...aray-pulsars/8547BD48EAC9A5C9BF8A38346ED506D1). The polarization is very complicated because it tends to be strongly affected by propagation effects, rather than simple source effects. By and large the polarization is elliptical, which implies a combination of both. I would say that answers to your question also relate to whether you are talking about spectrally integrated or spectrally resolved, because some types of polarization shift the frequency of the light in ways that would cancel out if you don't have sufficient spectral resolution.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
