Polarization studies and more with new ALMA capabilities

In this talk, I will illustrate how the planned upgrade of ALMA instantaneous spectral bandwidth, starting with the new Band 2 capabilities, will improve our understanding of Galactic dust polarization and the role of magnetic fields in the star formation process. In addition to the advantages for continuum studies, Band 2 will also be important for spectral line studies, in particular of deuterated species, and this also be briefly discussed.
