Description
The quest for the most distant galaxies and for the understanding
of galaxy formation and evolution in the early Universe remains
one of the challenges of contemporary astrophysics.
Spectacular breakthroughs have been during the last decade thanks
to 8-10m class telescopes and to HST.
In this context I will summarise recent results on searches
for z>6 galaxies in deep surveys targetting blank fields and
using gravitional lensing. I will also show what we have
learned so far about the properties of these galaxies in terms
of mass, age, SFR, extinction etc. and illustrate the importance
of different physical ingredients for the spectral models
used to infer these properties.
