N2 - We present a study of the environment of 27 z = 3-4.5 bright quasars from the MUSE Analysis of Gas around Galaxies (MAGG) survey. With medium-depth Multi Unit Spectroscopic Explorer (MUSE) observations (4 h on target per field), we characterize the effects of quasars on their surroundings by studying simultaneously the properties of extended gas nebulae and Ly alpha emitters (LAEs) in the quasar host haloes. We detect extended (up to approximate to 100 kpc) Ly alpha emission around all MAGG quasars, finding a very weak redshift evolution between z = 3 and z = 6.
