SUMMARY:Element pollution at the highest observable redshifts - Emma Ryan-
 Weber\, IoA

DESCRIPTION:We have detected the highest redshift Carbon in the intergalac
 tic medium\, a mere 1 billion years after the big bang\, at the end of an 
 era when the first stars are thought to have formed. The presence of this 
 Carbon is essential for determining when the products of stellar nucleosyn
 thesis escaped from galaxies and polluted the surrounding pristine interga
 lactic gas. I will discuss these observations in the context of the distri
 bution of baryonic matter in Universe.\n
