The FirstLight project aims to follow the formation of the first galaxies during Cosmic Dawn (z=5-15), by using the N-body+gas-dynamics code, ART with novel models of feedback and a resolution below 10 parsecs.
DATA RELEASE OF THE FIRSTLIGHT DATABASE:
This release includes the basic properties of the main galaxy progenitor of 290 zoom-in simulations (Ceverino, Klessen & Glover, 2018): virial mass and radius, stellar and gas mass of the galaxy and its SFR aproximately every 10 Myr.
Using this database you can build the star-formation histories of about 300 galaxies with stellar masses between 10^6 and 3 x 10^9 Msun. The evolution of the SFR in each galaxy is complex and diverse, characterized by bursts of star formation. Overall, first galaxies espend 70% of their time in these bursts. This diversity sets the mean and the mass-dependent scatter of the star-forming main sequence at z=5-15. More results can be found in Ceverino, Klessen & Glover (2018).
A second data release includes the spectral energy distributions in the rest-frame UV-optical from stellar light and nebular emission (lines+continuum). More results can be found in Ceverino, Klessen & Glover (2019).
