SUMMARY:The First Stars and Galaxies - Raffaella Schneider (INAF\, Osserva
 torio Astronomico di Roma\, Italy)
DTSTART:20141125T163000Z

CONTACT:David Titterington
DESCRIPTION:The formation of the first stars\, supernovae and black holes 
 is a critical phase of cosmic evolution: the Universe was transformed from
  its initial simple state to a highly complex system through the injection
  of the first heavy elements from supernovae and the emission of light fro
 m the first stars and accreting black holes.  It also witnessed the assemb
 ly of the first galaxies that\, according to the hierarchical structure fo
 rmation paradigm\, represent the building blocks of larger system\, such a
 s our own Milky Way.  Despite the remarkable advancements made in observat
 ional techniques and theoretical modelling\, the nature of the first stars
  and black holes\, and the impact they had on their environment and on the
  properties of the first galaxies and quasars remain largely unknown.  In 
 this talk\, I will give a review of the most recent results obtained by me
 ans of theoretical models of stellar evolution and nucleosynthesis\, semi-
 analytical and numerical modes of galaxy evolution\, and detailed comparis
 on with observational data from surveys at low and high redshifts.\n
