Rationale

The motive for the proposed symposium is based on various new observations that show close and detailed correspondence between magnetic field tracers and gas and dust tracers, such as the correlation between dust polarization and neutral hydrogen fibers (Clark et al 2014, Planck Coll. Int. XXXII. 2016), between dust polarization and Faraday rotation (Zaroubi et al 2015), or neutral hydrogen and Faraday rotation (Van Eck et al 2017, Kalberla et al 2017). These observations give new, exciting and often puzzling evidence for the close interaction between thermal and non-thermal interstellar components.

Many of these observations have become possible through new observational and analysis techniques. Detailed numerical simulations and theory of the physical processes at play are indispensable when attempting to understand these features. With these new results, it is both urgent and important to bring the community together to disseminate and discuss the newest results, their interpretation and the way forward.

The dates proposed are very preliminary and can be changed to (almost) anywhere from April - June 2019.
