Abstract

Based on an R-band imaging survey of high-redshift (z ≈ 2) QSOs with the 4.2m WHT, we report the detection of extensions to the nuclear PSFs of two radio-quiet and one radio-loud QSO. The extensions are most likely host galaxies, with luminosities of at least 3 – 7% of the QSO luminosity. The most likely values for the luminosities lie in the range 6 – 18% of the QSO luminosity (R ~ 19.8 – 20.9 mag). Our observations show that, if the extensions we have detected are indeed galaxies, extraordinary massive and luminous galaxies are not only characteristic of radio-loud objects, but of QSOs as an entire class. For a detailed description of this work, see Aretxaga, Boyle & Terlevich (1995) MNRAS, 275, L27.
