Observational campaigns have dramatically increased the sample of known LAEs, which now extends out to z=7. These discoveries have motivated numerous theoretical studies on the subject, which usually define LAEs in their models based on sharp Ly{\\alpha} luminosity and equivalent width (EW) cuts. While broadly representative, this procedure does not mimic the selection from observational programs in detail, which instead use cuts in various colour-spaces.
