The MOSEL Survey

Named after the beautiful wine regions in Germany, The Multi-Object Spectroscopic Emission Line (MOSEL) survey is an ongoing survey of star-forming galaxies around 12 billion light years away. The main objective is identify factors affecting the rise and fall of star formation activity in young galaxies.

Our targets include galaxies at z=3-4 that show intense star-forming activity. These are analogues to galaxies during the epoch of reionisation. They will help us estimate the production efficiency of hydrogen ionising photons and the growth of the ionisation bubbles created by the “first galaxies” in the first billion years.
