Rest-UV Properties of MUSE DR2 Galaxies in Redshifts 2.8 < z < 4.0

In recent years, deep field surveys from the Hubble Space Telescope and MUSE on the Very Large Telescope have shed light on early faint galaxies. The second data release from MUSE HUDF (Hubble Ultra Deep Field) Survey features MXDF (MUSE eXtremely Deep Field) with a 1 arcmin diameter field of view and a depth of 141 hours. This increased integration time allows for higher spatial and redshift resolutions. The high sensitivity of MUSE allowed for the detection of 1308 Ly-α emitter galaxies (LAEs) within redshifts 2.8 < z < 6.7. These LAEs provide good opportunities to study rest-UV properties in galaxies. We select a sample of 121 galaxies in redshift 2.8 < z < 4.0. Out of 121 galaxies, 99 are LAEs. This redshift range is constrained by galaxies with a large redshift confidence and signatures of Lyα, CIV λ1548,1550, HeII λ1640, and CIII] λ1907,9. Using this sample, we study the correlation between properties such as stellar mass, gas-phase metallicity, star-formation rate, line strengths, and redshift. We compare these results with those found for lower redshift galaxies. The various trends found between properties within our galaxy sample, as well as their similarities and differences with lower redshift galaxies must be further investigated.
