Why does a right-handed circular polarized wave get lagged when going through ionized plasma?

I have a question related to Faraday rotation. In Abigail Polin's Faraday rotation video I have seen that a linearly polarized wave can be decomposed in a left-handed circular wave and a right-handed ...

What is the status of gravitational wave detections in the CMB?

I've not been in the loop for this, but can someone tell me what the status is of primordial gravitational wave detections in the CMB? This can essentially be detected through B-mode polarization ...

Polarization of an emission line

Say I have a flux density spectrum of a galaxy, as well as polarization spectra for the object in U, Q, and P. I want to find the polarization of some emission line in the spectrum. First, I can fit a ...

How can maser emission be unpolarized?

I was reading that: However, unlike Galactic sources such as W3(OH), the emission is unpolarized and the 1667 MHz line is stronger than the 1665 MHz line. but how is this possible? Does not the ...

Is there a spectrum of polarization? Does polarization vary depending on wavelength, from one and the same source?

Is it possible, and does it occur naturally, that the light from the same source is simultaneously polarized differently at different wavelengths? Light can be polarized by interstellar magnetic ...
