« The Lyman alpha emitters: local and distant  »

Daniel Kunth

The Lyman alpha emitters (LAEs) are among the best tracers of distant galaxies and are especially suited for exploring the faint end of the luminosity function of the Lyman break galaxies. They allow to map large structures, explore the impact of massive star formation onto the ISM and IGM and question the role of dwarf galaxies to the re-ionisation of the Universe at z of 6-7. However LAEs form an heterogeneous class of objects since the Lyman alpha line is imprinted by the properties of the ISM medium in these galaxies. As such, studies of local LAEs with high spatial and spectroscopic details are of great importance. I'll review their properties newly outlined thought our ongoing LARS project (Lyman Alpha Reference Sample) at the HST and will emphasize the need to challenge and propose projects for UV astronomy in the near future.
