Scientific paper

Near-infrared J, H, and K measurements have been obtained of the continua of the quasar with the currently highest known redshift, Q0051-279 (z = 4.43), and a second very high-redshift quasar, Q0101-304 (z = 4.07). It is found that the rest-frame optical/ultraviolet continuum of Q0051-279 is considerably steeper than that seen in most lower-redshift quasars. In addition, for this quasar there is evidence for substantial excess emission at roughly 2300 Å, which is not easily explained by known quasar emission features.
