The properties of the rest-frame UV emission from low-metallicity starbursts are studyied in detail, with the aim of providing a basis for the interpretation of observations of high redshift galaxies in which zero or low-metallicity stars are forming. A number of important effects are included, which were not accounted for in the earlier work of Schaerer (2002) on the emission properties of low-metallicity galaxies. Among these are that the nebular line emission can be enhanced appreciably when particularly massive, hot stars are illuminating the gas within the galaxy. The authors also pay particular attention to the impact that 2-photon emission can have on the equivalent widths of emission lines, especially Ly_alpha and He II 1640.
This is the astro-ph blog of the Theoretical Modelling of Cosmic Structures group (TMoX) at the Max-Planck-Institute for Extraterrestrial Physics. We are an independent Max-Planck Research Group focusing on the various aspects in the formation and evolution of galaxies. Part of our focus is on the formation and evolution of early-type galaxies, super-massive black holes, the formation of the first structures in the universe and the enrichment history of the Universe. We are theoreticians using analytic modelling as well as numerical simulations in our work.
The CosmologyCake blog is dedicated to the discussion of research papers and current developments. We will regularly post interesting papers and comment on them. Feel free to leave your comments as well. We encourage authors of discussed papers to post replies if they wish to. Our aim is to provide a platform to discuss recent astro-ph papers within a wider audience. Please feel free to send papers you would like to be discussed to us at firstname.lastname@example.org.
