The Apparently Normal Galaxy Hosts for Two Luminous Quasars
John N. Bahcall, Sofia Kirhakos, Donald P. Schneider
HST images (with WFPC2) of PHL~909\ () and PG~0052251\ () show that these luminous radio-quiet quasars each occur in an apparently normal host galaxy. The…
HST and MERLIN Observations of the Jet in 3C273
J. N. Bahcall, S. Kirhakos, D. P. Schneider +5
We present red and blue images of the jet of the quasar 3C273 obtained with the WFPC2 on the Hubble Space Telescope as well as a new radio map made with the MERLIN array. The image…
The HST Quasar Absorption Line Key Project VII. Absorption Systems at
John N. Bahcall, Jacqueline Bergeron, Alec Boksenberg +9
We present evidence that clumps of \lya lines are physically associated with about half of the extensive metal-line systems (absorption systems with four or more observed metal-lin…
HST Images of Nearby Luminous Quasars II: Results for Eight Quasars and Tests of the Detection Sensitivity
John N. Bahcall, Sofia Kirhakos, Donald P. Schneider
HST observations of eight intrinsically luminous quasars with redshifts between and~ are presented. Seven companion galaxies brighter than lie within a p…
