Título/Title: Do we understand the temperature in Blue Compact Dwarf galaxies?
Resumo/Abstract: During the last decade, photoionization models for low-metallicity BCD galaxies have been systematically unsuccessful, in that the model temperature was smaller than the observed one, with important implications for the global energetics of the Early Universe. I shall analyse the origin of this problem and propose a solution. |
