The Intergalactic medium transmission towards z>4 galaxies with VANDELS and the impact of dust attenuation

Understand

Aims.

• Our aim is to estimate the intergalactic medium transmission towards UV-selected star-forming galaxies at redshift 4 and above and study the effect of the dust attenuation on these measurements.
• Methods.
• The ultra-violet spectrum of high redshift galaxies is a combination of their intrinsic emission and the effect of the Inter-Galactic medium (IGM) absorption along their line of sight.
