Introducing the FirstLight project: UV luminosity function and scaling
  relations of primeval galaxies
  We introduce the FirstLight project that aims to generate a large database of
high-resolution, zoom-in simulations of galaxy formation around the epoch of
reionisation ($z\geq6$). The first results of this program agree well with
recent observational constraints at z=6-8, including the UV luminosity function
and galaxy stellar mass function, as well as the scaling relationships between
halo mass, stellar mass, and UV magnitude. The UV luminosity function starts to
flatten below MUV>-14 due to stellar feedback in halos with maximum circular
velocities of V=30-40 km/s. The power-law slope of the luminosity function
evolves rapidly with redshift, reaching a value of alpha=-2.5 at z=10. On the
other hand, the galaxy stellar mass function evolves slowly with time between
z=8-10, in particular at the low-mass end.
