Tunable filter imaging of high redshift quasar fields
John Swinbank, Joanne Baker, Jordi Barr +2
We have used the Taurus Tunable Filter to search for Lyman alpha emitters in the fields of three high redshift quasar fields: two at z~2.2 (MRC B1256-243 and MRC B2158-206) and one…
Modelling the orientation of accretion disks in quasars using H-alpha emission
E. J. Down, S. Rawlings, D. S. Sivia +1
Infrared spectroscopy of the H-alpha emission lines of a sub-sample of 19 high-redshift (0.8 < z < 2.3) Molonglo quasars, selected at 408 MHz, is presented. These emission lines ar…
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…
The cluster environments of radio-loud quasars at 0.6 < z < 1.1
J. M. Barr, M. N. Bremer, J. C. Baker +1
We have carried out multicolour imaging of a complete sample of radio-loud quasars at 0.6 < z < 1.1 and find groups or clusters of galaxies in the fields of at least 8 and possibly…
Associated absorption in radio quasars. I. C IV absorption and the growth of radio sources
J. C. Baker, R. W. Hunstead, R. M. Athreya +4
We assess the global properties of associated C IV 1548,1550 absorption lines measured in the spectra of radio-loud quasars drawn from a near-complete, low-frequency selected sampl…
The cluster environments of radio loud quasars
J. M. Barr, M. N. Bremer, J. C. Baker +1
We have carried out multi-colour imaging of the fields of a statistically complete sample of low-frequency selected radio loud quasars at 0.6<z<1.1, in order to determine the chara…
