Description
A most exciting but still unknown process in modern astrophysics is how galaxy evolution develops from the last ten billion years. Star formation (SF) and accretion onto supermassive black holes (BHA) play this game. Around the peak of the SF and BHA rate histories (z=1-4), galaxies and stars develop in dusty heavily obscured environments, preventing optical/UV observations to reveal their nature. As opposite, IR spectroscopy (and photometry at higher redshift) will reveal physically galaxy evolution, allowing to measure through lines the main physical properties (e.g., ionization field, density, metallicity, gas velocities, etc.). The ESA-JAXA (preselected in M5) mission SPICA will do this.
