Talk Title: 
Star Formation and ISM Dynamics
Event description: 

Stars and star clusters form by gravitational collapse in regions of high density in the dynamically evolving magnetised multi-phase interstellar medium. The process of stellar birth is controlled by the intricate interplay between the self-gravity of the star-forming gas and various opposing agents, such as supersonic turbulence, magnetic fields, radiative feedback, cosmic rays, and gas pressure. I will discuss examples of recent progress and controversy, specifically, I will focus on current attempts to bring numerical simulations and theoretical models closer to the observational domain. In this context, I would like to report on the efforts in Heidelberg to model magnetic field evolution and generate synthetic polarisation and Faraday rotation maps for comparison with the observational data.
