DESCRIPTION:Within inflationary cosmology\, the thermal history of the uni
 verse starts with the so-called reheating era which smoothly connects the 
 end of inflation to the radiation era. During this epoch the inflaton fiel
 d decays into unknown states at an unknown rate and with unknown branching
  ratios\; but ultimately producing a plasma of Standard Models particles i
 n thermal equilibrium. In this talk\, we show that within many models of i
 nflation the current CMB measurements put non-trivial constraints on vario
 us kinematic properties of the reheating era. Conversely\, such a result s
 hows that comparing theoretical inflationary models to  cosmological obser
 vations can no longer be performed without specifying a minimal set of hyp
 othesis on how the reheating proceeded.
