Optically faint counterparts to the ISO-FIRBACK 170 micron population: the discovery of cold, luminous galaxies at high redshift
(2002-07)
We present Keck spectroscopy and UKIRT near-IR imaging observations of two 170micron-selected sources from the ISO-FIRBACK survey which have faint counterparts in the optical, and r-K~5. Both sources were expected to lie ...
Radio galaxy selected clusters at high redshift and associated ERO overdensities
(2000-10)
Galaxy clusters at high redshift present a superb opportunity to study galaxy evolution, with large galaxy samples at fixed distances. Several lines of evidence point towards large formation redshifts and passive evolution ...
Most Submillimetre Galaxies are Major Mergers
(2010-09-13)
We analyse subarcsecond resolution interferometric CO line data for twelve sub-millimetre-luminous (S850um > 5mJy) galaxies with redshifts between 1 and 3, presenting new data for four of them. Morphologically and kinematically ...
A Vigorous Starburst in the SCUBA Galaxy N2 850.4
(2003-07-11)
We present optical and near-IR spectroscopy of a z=2.38 hyperluminous IR galaxy, covering the restframe wavelength range from 1000-5000A. It appears to comprise two components separated by less than 1" on the sky (<8kpc); ...
