Abstract:
High-velocity clouds (HVCs) around the Milky Way provide direct evidence of ongoing gas accretion that could fuel the future star formation activity of the Galaxy. Theories and numerical simulations predict that the magnetic field significantly affects the efficiency of the mixing at the cloud-halo interface, which could in the long run affect the survival of the clouds. There have been active searches for magnetized HVCs using polarization observations. In this talk, I will discuss possible difficulties in detecting magnetized HVCs using Faraday rotation and how future radio polarimetric surveys will improve the situation.
