Why we need to map oxygen in the Universe

Nikos Prantzos (Institut d’Astrophysique de Paris, France)

I will present an overview of the role of oxygen in the chemical evolution of galaxies. In particular, I will discuss the role of the different observational constraints provided by this element and comment on the accuracies required to make progress in our understanding of chemical evolution at all redshifts.

Invited talk given at the meeting “Mapping Oxygen in the Universe“, Tenerife, Spain (14-18 May 2012)
