Abstract:
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.
