Testing the Evolutionary Link Between Submillimetre Galaxies and Quasars: CO Observations of QSOs at z~2
Kristen Coppin, Mark Swinbank, Roberto Neri +10
We have used the IRAM Plateau de Bure mm interferometer and the UKIRT 1-5 um Imager Spectrometer to test the connection between the major phases of spheroid growth and nuclear accr…
Representing complex data using localized principal components with application to astronomical data
Jochen Einbeck, Ludger Evers, Coryn Bailer-Jones
Often the relation between the variables constituting a multivariate data space might be characterized by one or more of the terms: ``nonlinear'', ``branched'', ``disconnected'', `…
Line Emission in the Brightest Cluster Galaxies of the NOAO Fundamental Plane and Sloan Digital Sky Surveys
L. O. V. Edwards, Michael J. Hudson, Michael L. Balogh +1
We examine the optical emission line properties of Brightest Cluster Galaxies (BCGs) selected from two large, homogeneous datasets. The first is the X-ray selected National Optical…
The obscured quasar population from optical, mid-infrared, and X-ray surveys
C. Vignali, A. Comastri, D. M. Alexander
Over the last few years, optical, mid-infrared and X-ray surveys have brought to light a significant number of candidate obscured AGN and, among them, many Type 2 quasars, the long…
Evidence for Galaxy Formation at High Redshift
T. Shanks, N. Metcalfe, R. Fong +3
We have shown previously that galaxy counts from the UV to the near-IR are well-fitted by simple evolutionary models where the space density of galaxies remains constant with look-…
Spectroscopic follow up of arclets in AC114 with the VLT
J. F. Le Borgne, L. Campusano, R. Pello +5
We present the first results on the VLT/FORS-1 spectroscopic survey of amplified sources and multiple images in the lensing cluster AC114. Background sources were selected in the c…
