Left: minimum-energy magnetic field strength distribution for all sources, along with the distributions for nuclear and extranuclear regions. The field strengths for the extranuclear regions are, on average, smaller and more narrowly distributed than those for the nuclear regions. Right: minimum-energy magnetic field strength distributions for regions within the SFRS and GOALS galaxies. The field strengths of regions within the SFRS galaxies are, on average, smaller and more narrowly distributed than those within the GOALS sources.
