A NICMOS imaging study of high-z quasar host galaxies

Abstract: We present the first results from a major Hubble Space Telescope programme designed to investigate the cosmological evolution of quasar host galaxies from z ≃ 2 to the present day. Here we describe J and H-band NICMOS imaging of two quasar samples at redshifts of 0.9 and 1.9 respectively. Each sample contains equal numbers of radioloud and radio-quiet quasars, selected to lie within the same narrow range of optical absolute magnitude (−24 ≥ M V ≥ −25). Filter and target selection were designed to ensure that a… Show more

“…From our fitted host galaxy model, we measure the luminosity in the V, R, and K bands, comparing these to the results Kukula et al (2001) and Ridgway et al (2001). In panels (a) and (c), we show the derived relations by each work (short dashed lines) together with a simple least squares regression line (dotted line) with 1σ error, estimated by drawing 1000 bootstraps from the literature sample.…”

“…The investigations to date (Ridgway et al 2001;Kukula et al 2001;Peng et al 2006) have determined only the most basic properties (luminosity and size) of the host galaxies for relatively small samples. The images are not sensitive enough to detect large-scale lowsurface brightness tidal features while the inner regions are strongly contaminated by the QSO.…”

“…Finally, we apply the corresponding k-correction for a typical elliptical galaxy (Coleman et al 1980), and we use the galaxy profile of Burkert et al (1993) in order to estimate the fraction of the total optical flux of the host galaxy which enters the slit. Making the reasonable assumption that the typical absolute magnitude of the host galaxy of radio quiet AGN is similar at z = 0.3 and at z = 1.5, (Kukula et al 2001, Fig. 7), we derive the following values:…”
