Ly α Halos around z ∼ 6 Quasars

We present deep MUSE observations of five quasars within the first Gyr of the universe (z ≳ 6), four of which display extended Lyα halos. After PSF subtraction, we reveal halos surrounding two quasars for the first time, as well as confirm the presence of two more halos for which tentative detection...
