Quasar composite spectrum of z ≥ 6.5 quasars, created based on 38 z ≥ 6.5 quasars, as a result of a near-infrared spectroscopic survey of z ≳ 6.5 quasars (Yang et al. 2021). The composite spectrum can be downloaded here. More details about the near-infrared spectroscopic observations and the spectral dataset can be found here.
