Given the ubiquity of magnetic fields in the universe, a crucial puzzle is how the universe was magnetized in the first place. Theoretical work has shown that outflows of gas and magnetic fields from galaxies and galaxy interactions may be able to magnetize the intragalactic medium. Most cosmological simulations of magnetic fields in the intragalactic medium are driven by observations of magnetic fields in large structures like clusters. Clusters, however, are formed by the accretion of smaller structures like groups. Unlike cluster environments which are dominated by ram pressure stripping and frequency high speed interactions, groups are dominated by low speed encounters, which has very different consequences for the evolution of the galaxies in the groups. To obtain more detailed information on the magnetic fields in the group environment, we propose to do deep, high-resolution, 3 cm and 6 cm radio continuum polarization observations of six compact groups with the ATCA. These observations will allow us to determine what the magnetic field looks like in some typical group environments, how the group environment might distort the galactic magnetic field structure, and whether the fields in the intragroup medium are ordered or random.
