Description
The Galactic magnetic field is one of the least understood components of the ISM. It influences processes over a large range of scales, from star-formation to the diffusion of cosmic rays within the Galaxy. However, the effects of the magnetic field remain poorly understood, in part due to difficulties in measuring its properties over a large enough dynamic range in scale. With the advent of Gaia, a new era for magnetic field studies has begun. We can now probe the magnetic field properties in 3D, using stellar polarimetry and Gaia distances. I will describe recent progress on mapping the magnetic field with this technique, leading to new insights on the magnetized ISM in the Solar neighborhood. I will discuss prospects for synergy between this tomographic mapping with the many probes of the magnetized ISM from the SKA.
