Faraday rotation of radio source polarization provides a measure of the integrated magnetic field along the observational lines of sight. We compare a new, large sample of Faraday rotation measures (RMs) of polarized extragalactic sources…
To study some characteristics of the interstellar medium, observational data of pulsars with large Faraday rotation values (|RM|> 300 rad / m2) were used. It was suggested and justified that large |RM| values can be due to the contribution…

Context. The existence of magnetic fields in the circumgalactic medium (CGM) is largely unconstrained. Their detection is important as magnetic fields can have a significant impact on the evolution of the CGM and, in turn, the fields can…
