9. The multi-scale baryon cycle from clouds to galaxies

Diederik Kruijssen (Univ. Heidelberg)

The cloud-scale physics of star formation and feedback represent the main uncertainties in galaxy formation and evolution simulations. I will present our group's efforts towards overcoming this problem by using empirical constraints on the molecular cloud lifecycle to motivate a new generation of sub-grid models in galaxy simulations. Specifically, I will show how we can use the multi-scale...

Galactic dust grains are aggregations of molecules in the interstellar medium, which form preferentially at denser locations. Dust plays a central role in galactic physics, it obscures the view on stars by its optical light absorption and obfuscates our view on the cosmic microwave background by its emission of the absorbed energy at longer wavelength. The structure of dust clouds as well as...

31. Galactic Cartography with 3D maps of interstellar dust using data from GAIA's astrometric mission
