201. Investigating the Evolution of Quasar Host Galaxies with NICMOS
... The host galaxies of low-z quasars . ... High-redshift quasars. Motivation: host galaxies and quasar evolution . ... The estimated galaxy luminosities are consistent with the values obtained for low- z quasars of the same luminosity. quasars, host galaxies . ... Conversely, quasar surveys provide an easy method of locating galaxies at large redshifts, so knowledge of the properties of quasar hosts offers a means of investigating the history and evolution of galaxies themselves. ...

... By undertaking a spectral and photometric investi gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...
