Abstract

Observations with the Wide-Field/Planetary Camera-2 of the Hubble Space Telescope are presented for three radio-loud quasars: 3C 48 (z = 0.367), B2 1425+267 (z = 0.366), and 3C 345 (z = 0.594). All three quasars have luminous (∼4 × L*) galaxies as hosts, which are either elliptical (B2 1425+267 and 3C345) or interacting (3C 48), and all hosts are 0.5-1.0 mag bluer in V-I than other galaxies with the same overall morphology at redshifts similar to those of the quasars. The host of 3C 48 has many H II regions and a very extended tidal tail. All nine of the radio-loud quasars studied here and in a previous paper by Bahcall et al. either have bright elliptical hosts or occur in interacting systems. There is a robust correlation between the radio emission of the quasar and the luminosity of host galaxy; the radio-loud quasars reside in galaxies that are on average ∼ 1 mag brighter than hosts of the radio-quiet quasars.
