We aim to characterise the source population of the polarised sky in the L-Band using polarised source information in combination with IR and optical data.
We analyse five early science datasets from the APERture Tile in Focus (Apertif) phased array feed system to verify the polarisation capabilities of Apertif in view of future larger data releases. Ancillary infrared (IR) and optical data can be used to study the nature of the emitting objects.Īims. The origin of the polarised emission and the characteristics of the intergalactic medium on the line of sight can be investigated using large samples of polarised sources. The characteristics of the polarised radio sky are a key ingredient in constraining evolutionary models of magnetic fields in the Universe and their role in feedback processes.
