Circumgalactic Ly$\alpha$ emission around submillimeter-bright galaxies with different quasar contributions

Vale González Lobos, Fabrizio Arrigoni Battaia, Seok-Jun Chang +6

We present VLT/MUSE observations targeting the extended Lyman-$\alpha$ (Ly$\alpha$) emission of five high-redshift ($z\sim$3-4) submillimeter galaxies (SMGs) with increasing quasar (QSO) rad…
