Circular polarization is produced either in the emission process through the Zeeman effect, or through the transfer of polarized radiation in a magneto-active medium. While the former mechanism provides a direct access to the strength of the magnetic field along the sightline, the conversion of linear to circular polarization reveals particular...

Context. The Central Molecular Zone (CMZ), a ∼200 pc sized region around the Galactic Centre, is peculiar in that it shows a star formation rate (SFR) that is suppressed with respect to the available dense gas. To study the SFR in the CMZ, young stellar objects (YSOs) can be investigated. Here we present radio observations of 334 2.2 μm...
