RXJ0152.7-1357: Stellar populations in an X-ray luminous galaxy cluster at z=0.83

Inger Jorgensen, Marcel Bergmann, Roger Davies +3

We present a study of the stellar populations of galaxies in the cluster RXJ0152.7-1357 at a redshift of 0.83. The study is based on new high S/N spectroscopy of 29 cluster members…

Tunable-filter imaging of quasar fields at z ~ 1. II. The star-forming galaxy environments of radio-loud quasars

J. M. Barr, J. C. Baker, M. N. Bremer +2

We have scanned the fields of six radio-loud quasars using the Taurus Tunable Filter to detect redshifted [OII] 3727 line-emitting galaxies at redshifts 0.8 < z < 1.3. Forty-seven…
