- W2247776368 abstract "The VLT Multi Unit Spectroscopic Explorer (MUSE) integral-field spectrograph can detect Lyalpha{} emitters (LAE) in the redshift range $2.8 lesssim z lesssim 6.7$ in a homogeneous way. Ongoing MUSE surveys will notably probe faint Lyalpha{} sources that are usually missed by current narrow-band surveys. We provide quantitative predictions for a typical wedding-cake observing strategy with MUSE based on mock catalogs generated with a semi-analytic model of galaxy formation coupled to numerical Lyalpha{} radiation transfer models in gas outflows. We expect $approx$ 1500 bright LAEs ($F_{Lyalpha}$ $gtrsim$ $10^{-17}$ erg s$^{-1}$ cm$^{-2}$) in a typical Shallow Field (SF) survey carried over $approx$ 100 arcmin$^2$, and $approx$ 2,000 sources as faint as $10^{-18}$ erg s$^{-1}$ cm$^{-2}$ in a Medium-Deep Field (MDF) survey over 10 arcmin$^2$. In a typical Deep Field (DF) survey of 1 arcmin$^2$, we predict that $approx$ 500 extremely faint LAEs ($F_{Lyalpha}$ $gtrsim$ $4 times 10^{-19}$ erg s$^{-1}$ cm$^{-2}$) will be found. Our results suggest that faint Lyalpha{} sources contribute significantly to the cosmic Lyalpha{} luminosity and SFR budget. While the host halos of bright LAEs at z $approx$ 3 and 6 have descendants with median masses of $2 times 10^{12}$ and $5 times 10^{13}$ $M_{odot}$ respectively, the faintest sources detectable by MUSE at these redshifts are predicted to reside in halos which evolve into typical sub-$L^{*}$ and $L^{*}$ galaxy halos at z = 0. We expect typical DF and MDF surveys to uncover the building blocks of Milky Way-like objects, even probing the bulk of the stellar mass content of LAEs located in their progenitor halos at z $approx$ 3." @default.
