The Hamburg/SAO survey for low metallicity BCGs (HSS-LM)

The description and the first results of the new project will be presented. It is devoted to the search for the most metal-deficient blue compact galaxies. The first goal is to extend the sample of the most interesting candidates to truly young galaxies in the local Universe, and study them in detail. The second goal of the project is to create a large, clearly selected sample of BCGs with reliably measured O/H. The data will be used for the statistical analysis of metallicity along with the global galaxy parameters and its environment. They will be used to confront the observed relationships with model predictions.
