Abstract

We present a measurement of the fraction of Lyman $\alpha$ (Ly$\alpha$) emitters ($X_Ly \alpha$) amongst HST continuum-selected galaxies at $3<z<6$ with the Multi-Unit Spectroscopic Explorer (MUSE) on the VLT. Making use of the first 24 MUSE-Wide pointings in GOODS-South, each having an integration time of 1 hour, we detect 100 Ly$\alpha$ emitters and find $X_Ly \alpha\gtrsim0.5$ for most of the redshift range covered, with 29% of the Ly$\alpha$ sample exhibiting rest equivalent widths (rest-EWs) $łeq$ 15\AA. Adopting a range of rest-EW cuts (0 - 75\AA), we find no evidence of a dependence of $X_Ly \alpha$ on either redshift or UV luminosity.
