Abstract:

Using panchromatic observations ranging from the 21cm H I line in the radio regime to the extreme ultraviolet (UV), we studied ionizing radiation from massive stars (direct and through hydrogen recombination lines) as well as the atomic and molecular gas content in 15 highly star-forming local galaxies. The results are brought into cosmological context, taking a step forward towards finding answers to the followin open questions in galaxy evolution: Which physical conditions enable galaxies to leak ionizing radiation (and power reionization)? What drives the high Lyman-alpha escape fractions observed in the early Universe? How did the massive stellar clumps found in high redshift
galaxies have possibly formed?
