Astrophysical magnetic fields

Magnetic fields are produced by electrical currents that are generated by various astrophysical objects. The study of magnetic fields seeks to understand their origin, as well as the acceleration of charged particles in such fields, and includes numerical simulations and observational studies of magnetism in astrophysical environments.

    Observations have mapped the distribution of gas velocities in a circumstellar disk wind for the first time. The high spatial resolution required for these observations is achieved by measuring the maser emission of water molecules. These findings validate theoretical predictions from the 1980s and can be replicated by modern numerical models.
