DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CENTRA/3/">T
 he evolving shapes of star-forming galaxies in the young Universe</a>\nby 
 Bruno Ribeiro (Leiden Observatory\, Leiden U.) as part of CENTRA Seminar\n
 \n\nAbstract\nThe global properties of galaxies show a strong evolution of
  the star formation rate and stellar mass density at the epoch of galaxy a
 ssembly\, driven by several competing physical processes (merging\, accret
 ion\, feedback\, environment\,...). The morphological properties of galaxi
 es are also strongly evolving over the same timescales. In such early stag
 e evolution\, galaxy evolution is believed to be a turbulent process where
  gas inflows\, strong winds and galaxy-galaxy interactions give rise to th
 e intricate shapes that we encounter in HST photometric observations of hi
 gh redshift galaxies. The shape of galaxies is a simple\, yet fundamental\
 , property of galaxies. In this talk\, I would like to highlight two main 
 results on the evolution of rest-frame UV galaxy morphology  at 2<z<6 from
  the largest spectroscopic survey taken to date at these epochs (VIMOS Ult
 ra Deep Survey): 1) galaxies are not as small as we might have thought\; 2
 ) clumpy-looking galaxies are increasingly common at higher lookback times
  and a significant fraction is of merger nature. I will then discuss the i
 mplications of these new findings for future surveys with special emphasis
  on synergies with Euclid and JWST which are the only missions capable of 
 observing optical emission from these distant galaxies.\n
