The hosts of $z=2$ QSOs
Abstract
We present results of the hosts of four high-redshift () and high luminosity ( mag) QSOs, three radio-quiet one radio-loud, imaged in R and K bands. The extensions to the nuclear unresolved source are most likely due to the hosts galaxies of these QSOs, with luminosities at rest-frame 2300\AA of at least 3-7% of the QSO luminosity, and most likely around 6-18% of the QSO luminosity. Our observations show that, if the extensions we have detected are indeed galaxies, extraordinary big and luminous host galaxies are not only a characteristic of radio-loud objects, but of QSOs as an entire class.
