Scientists explain the behaviour of the optical emission of blazars

Researchers have found that the polarisation plane of visible light in blazars sometimes rotates, coinciding with repeated gamma ray bursts. The study also described the structure of the inner part of the jets, revealing a fast spine surrounded by a slower sheath with ring condensations.
