Stellar mass versus the age of the stellar population, as determined by SED-fitting of exponentionally declining star formation histories. The coloured dots correspond to a variety of results from previous spectroscopically-confirmed LAE studies, while the grey squares correspond to the collection of composites assembled by McLinden et al. (2014). For comparison, we also plot a sample of non-LAE, represented by the pink dots (Finkelstein et al. 2015).
