DESCRIPTION:Comprehensive and systematic studies of the molecular content 
 of galaxies during the epochs that are associated with the peak (z approx 
 1-3)\, and subsequent winding down (z < 1) of star formation in the Univer
 se are enabling us to illustrate the important role that cold gas\, the fu
 el for star formation\, has played in the assembly of galaxies across cosm
 ic time.  Modest sized surveys already provide robust molecular gas detect
 ions in hundreds of normal\, star forming galaxies (SFGs)\, from redshifts
  0-2.5.  Furthermore\, spatially resolved spectroscopy in both the (sub)mm
  and NIR wavelengths now enable us to study the detailed kinematics\, star
  formation\, and ISM properties in SFGs on few kpc scales.  In this talk\,
  we focus on results from PHIBSS\, an IRAM legacy program with NOEMA\, whe
 re we are mapping the CO J=3-2 or J-2-1 line emission in approximately 200
  such galaxies from z=0.5-2.5\; we find that galaxies at these epochs are 
 very gas rich\, relative to their star-forming counterparts in the local U
 niverse.  These SFGs likely develop from continuous\, rapid accretion of g
 as from their dark matter halos\, and their evolution is strongly influenc
 ed by internal\, secular evolution\, and by powerful feedback from star fo
 rmation and accreting central massive black holes.  We also discuss the fi
 rst scaling relations for massive star forming galaxies that we derive fro
 m these data\, and the impact of all these new observations on our underst
 anding of galaxy evolution in the early Universe.\n
