HST and UKIRT imaging observations of z 1 6C radio galaxies - I. The data

HST and UKIRT imaging observations of z ∼ 1 6 C radio galaxies - I . The data

The results of Hubble Space Telescope and UKIRT imaging observations are presented for a sample of 11 6C radio galaxies with redshifts 0.85 < z < 1.5. The observations of the 6C sources reveal a variety of different features, similar to those observed around the higher power 3CR sources of similar redshifts. However, the extent and luminosity of the aligned emission appears less extreme in the ...

HST and UKIRT imaging observations of z ∼ 1 6 C radio galaxies - II . Galaxy morphologies and the alignment effect

Powerful radio galaxies often display enhanced optical/UV emission regions, elongated and aligned with the radio jet axis. The aim of this series of papers is to separately investigate the effects of radio power and redshift on the alignment effect, together with other radio galaxy properties. In this second paper, we present a deeper analysis of the morphological properties of these systems, i...

HST , radio and infrared observations of 28 3 CR radio galaxies at redshift z ∼ 1 — I . The observations

Hubble Space Telescope images are presented of a sample of 28 3CR radio galaxies with redshifts in the range 0.6 < z < 1.8, together with maps at comparable angular resolution of their radio structure, taken using the Very Large Array. Infrared images of the fields, taken with the United Kingdom InfraRed Telescope, are also presented. The optical images display a spectacular range of structures...

HST Imaging of z > 0 . 4 Quasar Host Galaxies Selected by Quasar Radio and Optical Properties

A sample of 16 quasars selected from the Large Bright Quasar Survey in the redshift range 0.4 < z < 0.5 has been imaged in the R band with the Planetary Camera on the WFPC2 instrument of the Hubble Space Telescope. The host galaxy magnitudes are mostly similar to or brighter than L∗, and the host luminosity is positively correlated with the luminosity of the quasar nuclear component. There is n...
