With new large surveys and space missions on the horizon, we<span class="Apple-converted-space"> </span><br class="">are now suited to explore new, bold and more detailed questions in the<span class="Apple-converted-space"> </span><br class="">2020s: When did the first stars form and what were their properties?<span class="Apple-converted-space"> </span><br class="">Which sources of light were the main drivers of cosmic reionisation?<span class="Apple-converted-space"> </span><br class="">What drives the variation in galaxy' star formation histories and their<span class="Apple-converted-space"> </span><br class="">chemical evolution, and how is this connected to the dark matter<span class="Apple-converted-space"> </span><br class="">assembly? These questions are particularly challenging as they describe<span class="Apple-converted-space"> </span><br class="">complex, multi-scale and multi-dimensional phenomena. Observations<span class="Apple-converted-space"> </span><br class="">furthermore are fundamentally limited by resolution and sensitivity and<span class="Apple-converted-space"> </span><br class="">can not be used for longitudinal studies. In this framework, I will<span class="Apple-converted-space"> </span><br class="">first discuss results from cosmological hydrodynamical simulations. I<span class="Apple-converted-space"> </span><br class="">will present explorations of the multi-dimensional relations between the<span class="Apple-converted-space"> </span><br class="">assembly of dark matter halos, star formation histories and stellar<span class="Apple-converted-space"> </span><br class="">alpha-enhancement that can be tested with large upcoming galaxy surveys.<span class="Apple-converted-space"> </span><br class="">I will then move to the mostly uncharted territory of the observational<span class="Apple-converted-space"> </span><br class="">study of the most distant galaxies and present results from recent<span class="Apple-converted-space"> </span><br class="">attempts to witness the assembly of galaxies in the first few Gyr of<span class="Apple-converted-space"> </span><br class="">cosmic time. I will emphasise the role of the bright Lyman-alpha line in<span class="Apple-converted-space"> </span><br class="">observations of faint distant galaxies to study the process of<span class="Apple-converted-space"> </span><br class="">reionisation, and to help identifying galaxies with very young stellar<span class="Apple-converted-space"> </span><br class="">populations.
