This paper presents a simple model of polarisation rotation in optically thin relativistic jets of blazars. The model is based on the development of helical (kink) mode of current-driven instability. A possible explanation is suggested for the observational connection between polarisation rotations and optical/gamma-ray flares in blazars. if the current-driven modes are triggered by s... https://hollandscountryclothinges.shop/product-category/hiking-shoes/
