Equivalent widths of Lyman <i>α</i> emitters in MUSE-Wide and MUSE-Deep

The aim of this study is to better understand the connection between Lyman $\alpha$ rest-frame equivalent width (EW$_0$) and spectral properties as well ultraviolet (UV) continuum morphology by obtaining reliable EW$_0$ histograms for a statistical sample galaxies assessing fraction objects with large widths. We used integral field spectroscopy from MUSE combined broad-band data Hubble Space Telescope (HST) measure EW$_0$. analysed emission lines $1920$ emitters (LAEs) detected in full MUSE-Wide (one hour exposure time) MUSE-Deep (ten surveys found UV counterparts archival HST data. fitted photometric images using Galfit software gain morphological information on rest-UV spectra obtained determine double peak fraction, asymmetry, full-width at half maximum, flux line. two show different In MUSE-Wide, $20\%$ have EW$_0 > 240$ \r{A}, while only $11\%$ $\approx 16\%$ sample. This includes without (one-third our sample), which we give lower limits object highest securely measured has EW$_0=589 \pm 193$ \r{A} (the limit being EW$_0=4464$ \r{A}). investigate or properties. survey depth be taken into account when studying distributions. find that general, high can wide range properties, might reflect underlying causes values are equally varied.
