I What is “absolute circular polarization fraction” for a pulsar?

AI Thread Summary
The discussion centers on the concept of "absolute circular polarization fraction" in pulsars, distinguishing it from the standard circular polarization fraction. The term "absolute" refers to the absolute value, indicating the distance from zero without regard to direction. This means it measures the extent of polarization regardless of whether it is positive or negative. An example from a pulsar study is referenced to illustrate the concept. The conversation also touches on the challenges of accessing information in different countries due to legal restrictions.

In a pulsar paper, two terms were mentioned: circular polarization fraction and absolute circular polarization fraction.
1. What is the absolute circular polarization fraction?
2. What is the difference between them?

Thank you.
I envy your freedom to use Google. It is illegal to use Google in our country.

Yes, different countries, and different politicians, load all of us with rules. Some are a good idea and some are not.

Stay Safe!

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...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
