Abstract
Subject headings
Close
- Magnetic fields play an important role in shaping the structure and evolution of the interstellarmedium (ISM) of galaxies, but the details of this relationship remain unclear. With SKA1, the 3Dstructure of galactic magnetic fields and its connection to star formation will be revealed. A highlysensitive probe of the internal structure of the magnetoionized ISM is the partial depolarizationof synchrotron radiation from inside the volume. Different configurations of magnetic field andionized gas within the resolution element of the telescope lead to frequency-dependent changesin the observed degree of polarization. The results of spectro-polarimetric observations are tiedto physical structure in the ISM through comparison with detailed modeling, supplemented withthe use of new analysis techniques that are being actively developed and studied within the communitysuch as Rotation Measure Synthesis. The SKA will enable this field to come into its ownand begin the study of the detailed structure of the magnetized ISM in a sample of nearby galaxies,thanks to its extraordinary wideband capabilities coupled with the combination of excellentsurface brightness sensitivity and angular resolution.
