The Sample

Currently, our sample consists of 31 quasars in the redshift range 5.77<z<6.62 located in the southern sky. Observations have been collected with the MUSE instrument on the VLT telescope YEPUN as a part of the ESO programs: 60.A-9321(A, Science Verification), 094.B-0893(A, PI: Venemans), 095.B-0419(A, PI: Roche), 095.A-0714(A, PI: Karman), 099.A-0682(A, PI: Farina), 0101.A-0656(A, PI: Farina), 0103.A-0562(A, PI: Farina), and 297.A-5054(A, PI: Decarli).

These quasars have an average redshift of z=6.22 and an average absolute magnitude of M₁₄₅₀=-26.9mag. Among these, only J2228+0110 is a confirmed radio-loud quasar. For most of our targets, sensitive ALMA observations of the [CII] fine-structure line and of the underlying dust continuum have been collected (Decarli et al. 2017, 2018, Venemans et al. 2018).
