摘要

We have taken deep, moderate‐resolution Keck/DEIMOS spectra of the quasar (QSO) CFHQS J232908.28−030158.8 at z= 6.4. At the wavelength of Lyα, the spectrum shows a spatially extended component, which is significantly more extended than a stellar spectrum, and also a continuum part of the spectrum. The rest‐frame linewidth of the extended component is 21 ± 7 Å and thus smaller than that of the QSO...
