Abstract:
We present a measurement of the fraction of Lyman α (Lyα)
emitters (XLyα) 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 1h, we detect 100Lyα emitters and
find XLyα≳0.5 for most of the redshift range covered, with
29 per cent of the Lyα sample exhibiting rest equivalent
widths (rest-EWs)≤15Å. Adopting a range of rest-EW cuts
(0∼75Å), we find no evidence of a dependence of XLyα on
either redshift or ultraviolet luminosity.
Description:
The MUSE-Wide project (see also Herenz et al., 2017A&A...606A..12H 2017A&A...606A..12H,
Cat. J/A+A/606/A12) is a blind spectroscopic survey (PI: L. Wisotzki)
using the MUSE panoramic integral field spectrograph at the ESO-VLT,
carried out as a part of the GTO awarded to the MUSE consortium. The
final survey covers some 100-arcmin2 in areas with deep HST imaging
and complementary multiwavelength data, with the Chandra Deep
Field-South (CDFS) as the primary region of interest. MUSE covers a
fixed spectral range from 4750 to 9300Å with a resolution of
2.5Å (full width at half-maximum).
This paper uses data from the first 24 MUSE-Wide pointings in the
CDFS-Deep part of the CANDELS HST imaging survey (Cosmic Assembly
Near-Infrared Deep Extragalactic Legacy Survey), which in turn was
built on top of the earlier GOODS imaging campaign (Giavalisco et al.,
2004ApJ...600L..93G 2004ApJ...600L..93G, Cat. II/261). Our 24 MUSE fields are also all
located within the footprint of the 3D-HST grism survey (Brammer et
al., 2012ApJS..200...13B 2012ApJS..200...13B; Momcheva et al., 2016, Cat. J/ApJS/225/27).
