Spectroscopic follow-up of a cluster candidate at z = 1.45 (2007)
Van Breukelen, Caroline, Cotter, Garret, Rawlings, Steve, Readhead, Tony, Bonfield, David, Clewley, Lee, ...
We have obtained deep optical spectroscopic data of the highest-redshift cluster candidate (z ~ 1.4, CVB13) selected by Van Breukelen et al. (2006) in a photometric optical/infrared catalogue of the...
Detecting galaxy clusters at 0.1 < z < 2.0 (2006)
Clewley, Lee, Van Breukelen, Caroline, Bonfield, David
We present a new cluster-finding algorithm based on a combination of the Voronoi Tessellation and Friends-Of-Friends methods. The algorithm utilises probability distribution functions derived from a...
A new method of detecting high-redshift clusters (2006)
Van Breukelen, Caroline, Clewley, Lee, Bonfield, David
We present a new cluster-finding algorithm based on a combination of the Voronoi Tessellation and Friends-Of-Friends methods. The algorithm utilises probability distribution functions derived from a...
Van Breukelen, Caroline, Jarvis, Matt J., Venemans, Bram P.
We have used VIsible MultiObject Spectrograph Integral-Field Unit (VIMOS-IFU) observations centred on a radio galaxy at z=2.9 to search for Ly-alpha emitters within a comoving volume of ~ 10^4 Mpc^3....
The discovery of a type-II quasar at z = 1.65 with integral-field spectroscopy (2004)
Jarvis, Matt J., Van Breukelen, Caroline, Wilman, R. J.
In this letter we report the serendipitous discovery of a genuine type-II quasar at z = 1.65 using integral-field data from VIMOS on the VLT. This is the first discovery of a type-II quasar at z > 1...
