JHK observations of two Z = 3 QSOs
Abstract
Infrared observations of the QSOs PKS 2126-15 (z = 3.27) and Q 0420-388 (z = 3.13), believed to be intrinsically the most luminous known, are discussed along with data from other spectral regions. Attention is given to the distribution of luminosity with frequency; the infrared fluxes from the two QSOs are almost identical, and the slopes of f(nu) in the rest frame near visible wavelengths are around -0.5. The two QSOs are shown to have bolometric luminosities in excess of 3 x 10 to the 41st W (q(o) = 0).
