This large sample of galaxies with secure spectroscopic redshifts will enable a number of detailed studies from 3×109 to 5×108 years
after the Big Bang, most importantly:
- the evolution of the global star formation rate and the build up of the mass function for different galaxy populations;
- the study of very young galaxies and search for the long sought PopIII stellar populations;
- a measurement of the clustering of galaxies to infer the mass growth of underlying dark matter halos;
- a measurement of the merger rate to evaluate the contribution of mergers to the mass growth of galaxies at these early epochs;
These measurements will be used to build a clear and comprehensive picture describing the physical processes which regulate star formation and stellar mass assembly
in galaxies in their early phases of evolution.
