The discovery and characterization of primeval galaxies represent some of the biggest challenges of current observational and theoretical cosmology. This kind of studies recently entered a golden era, thanks to the unprecedented capabilities of the Atacama Large Millimeter Array (ALMA). Far infrared fine structure lines—[CII]158?m in particular—are exquisite tools to search for and characterize the most remote system in the Universe. These experiments can be combined with detailed galaxy simulations to achieve a solid theoretical understanding.

I will present zoom-in, AMR , high-resolution (30 pc) simulations of high-redshift (z~6) galaxies with the aim of characterizing their internal properties and interstellar medium. Comparing our simulations with observations allow us to draw novel and unique conclusions. In addition, such comparison is fundamental to constrain feedback prescriptions in simulations, which are a far cry from being fully understood.
