Invited talk

The Galactic magnetic field is one of the least understood components of the ISM. It influences processes over a large range of scales, from star-formation to the diffusion of cosmic rays within the Galaxy. However, the effects of the magnetic field remain poorly understood, in part due to difficulties in measuring its properties over a large enough dynamic range in scale. With the advent of...

Contributed talk

Quantifying the number density and physical characteristics of extragalactic polarized sources is crucial for future Faraday Rotation Measure studies to probe Galactic and intergalactic magnetic fields. We present a polarimetric study at 114.9–177.4 MHz of the ELAIS-N1 LOFAR deep field. An area of 25 deg^2 was imaged at 6”-resolution in the Stokes Q,U parameters. A 1σ sensitivity of 19...
