Towards a panchromatic picture of galaxy evolution during the reionization epoch

There are thousands of confirmed detections of star forming galaxies at high redshift (z > 4). These observations rely primarily on the detection of the spectral Lyman Break and the Lyman-alpha emission line. Theoretical modelling of these sources helps to interpret the observations in the framework of the standard cosmological paradigm. We present results from the High-z MareNostrum Project, aimed at constructing a panchromatic picture of the high redshift galaxy evolution that will improve our understanding of young star forming galaxies. Our simulation successfully reproduces the observational constraints from Lyman Break Galaxies and Lyman-alpha emitters at 5 < z < 7 . Based on this model we make predictions on the expected Far Infrared (FIR) emission that should be observed for LAEs. These predictions will help to settle down the question on the dust content of massive high-z galaxies, an issue that will be feasible to probe observationally with the Atacama Large Millimetre Array (ALMA).
