The evolution of the Fundamental Plane of radio galaxies from z~0.5 to the present day
Peter D. Herbert, Matt J. Jarvis, Chris J. Willott +5
We present deep spectroscopic data for a 24-object subsample of our full 41-object z~0.5 radio galaxy sample in order to investigate the evolution of the Fundamental Plane of radio…
The ultracool-field dwarf luminosity-function and space density from the Canada-France Brown Dwarf Survey
C. Reyle, P. Delorme, C. J. Willott +7
Context. Thanks to recent and ongoing large scale surveys, hundreds of brown dwarfs have been discovered in the last decade. The Canada-France Brown Dwarf Survey is a wide-field su…
The WIRCAM Deep Infrared Cluster Survey I: Groups and Clusters at z > 1.1
R. M. Bielby, A. Finoguenov, M. Tanaka +12
We use CFHTLS deep optical data, WIRCam Deep Survey (WIRDS) NIR data and XMM data to identify z>1.1 clusters in the CFHTLS D1 and D4 fields. Counterparts to such clusters can not b…
Eddington-limited accretion and the black hole mass function at redshift 6
Chris J. Willott, Loic Albert, Doris Arzoumanian +7
We present discovery observations of a quasar in the Canada-France High-z Quasar Survey (CFHQS) at redshift z=6.44. We also use near-IR spectroscopy of nine CFHQS quasars at z~6 to…
The extinction law at high redshift and its implications
S. Gallerani, R. Maiolino, Y. Juarez +9
We analyze the optical-near infrared spectra of 33 quasars with redshifts 3.9<z<6.4 to investigate the properties of dust extinction at these cosmic epochs. The SMC extinction curv…
Evidence of different star formation histories for high- and low-luminosity radio galaxies
Peter D. Herbert, Matt J. Jarvis, Chris J. Willott +5
We present the results of our investigation into the stellar populations of 24 radio galaxies at z~0.5 drawn from four complete, low-frequency selected radio surveys. We use the st…
