I will present first results on the Lyα luminosity function in the Hubble Ultra Deep Field (HUDF), using a large, homogeneous, sample of LAEs selected through blind spectroscopy from MUSE. The unprecedented detection power of MUSE gives us the sensitivity to study the progenitors of L∗ galaxies when the Universe was just ∼ 2 Gyr old. These data therefore probe further down the Lyα LF than ever before, allowing us to reliably constrain the faint end slope, α, at high redshift, as well as assessing the evolution of the Lyα LF between z ∼ 3.0 and z ∼ 6.5. Finally I will show the first assessment from MUSE of the contribution of LAEs to the cosmic SFRD across this redshift range, and discuss the implications of our results on models of galaxy formation and evolution.
