Simultaneous single-pulse polarization observations reveal pulsar radiation behaviors

There is a considerable mass of jargon in this article. Specifically
In addition, through cross-correlation analysis for simultaneous observations, the researchers found that the total intensity of single pulses was highly correlated between 732 and 3100 MHz. With investigation of the separation values of PA-jumping phase bins, they confirmed that the abrupt PA jumps observed in PSR J0953+0755 were non-orthogonal at three frequencies in this pulsar.

"Furthermore, the separation angle between different polarization modes is frequency-dependent," said Rukiye.

They also found that the dominant polarization modes were associated with negative values of circular polarization, but the association seemed unclear for weak modes.
To translate:

We looked for correlations and found a high degree of correlation between the intensities of pulses at 732 and 3100 MHz. We found that the polarization angle (PA) jumps were not perpendicular at three frequencies.

The separation angle between different polarizations depends on frequency.

The main modes of polarization were associated with circular polarizations obeying a left handed rule.

I'm waiting for someone to propose the left handed circular polarization as evidence for alien analogues of the golden scarab beetle. ;)
