The Magnetized Universe: From planet-forming disks to the high-redshift universe
Abstract
The interstellar medium (ISM) is magnetized at all scales and phases in our Galaxy and other galaxies across the Universe. Spectro-polarimetric millimetre observations are essential to probe the role of the interstellar magnetic fields in the dynamics of the cold universe, and how this affects the star formation process, and planet formation in nearby star forming regions. Such observations are also essential for understanding magnetic fields in active stars and the shaping and evolution of the circumstellar environments of evolved stars. While ALMA has been revolutionary in advancing our knowledge about magnetic fields in the ISM, the limitations in calibration, especially for circular polarization, and sensitivity for large samples, have hindered robust measurements of field strengths, which are essential for fully assessing their role in ISM dynamics. An ALMA2040 that broadens spectro-polarimetric capabilities to include robust circular calibration and increases sensitivity with more collecting area will enable crucial observations of magnetic fields across the Universe and over a wide range of spatial scales to fully ascertain the influences of magnetic fields from galaxy assembly to forming planets.
