" Massive Galaxies at 2< z <4: New Insights into Galaxy Formation and Evolution "
Danilo Marchesini
(Tufts University, USA)
As the redshift range z=2-4 represents a key epoch in the buildup and evolution
of galaxies, studies of the properties of galaxies at these redshifts provide
important clues on the physical processes at work during galaxy formation and
evolution. I will present results on the evolution of the stellar mass function
of galaxies at 1.5< z <4 from the MUSYC, FIREWORKS, and FIRES surveys, putting
particular stress on its uncertainties, especially the systematics. I will then
present the most recent results from the NEWFIRM Medium-Band Survey (NMBS),
focusing on the properties of the most massive galaxies at 3< z <4, on the unexpected
results the NMBS data quality and wavelength coverage have returned, and on their
implications for our understanding of galaxy evolution. Finally, I will conclude
with an overview of ongoing projects aiming to further improve our knowledge on
the high-redshift universe.
