The HDF-North SCUBA Super-map I: Submillimetre maps, sources and number counts
We investigate the emission of sub-millimetre-wave radiation from galaxies in a 165 square arcminute region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and ...
Exploring the Properties of the M31 Halo Globular Cluster System
Following on from our discovery of a significant population of M31 outer halo globular clusters (GCs), and updates to the Revised Bologna Catalogue of M31 GCs, we investigate the GC system of M31 out to an unprecedented ...
A Vigorous Starburst in the SCUBA Galaxy N2 850.4
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); ...
Herschel observations of a z 2 stellar mass selected galaxy sample drawn from the GOODS NICMOS Survey
We present a study of the far-IR properties of a stellar mass selected sample of 1.5 9.5 drawn from the GOODS NICMOS Survey (GNS), the deepest H-band Hubble Space Telescope survey of its type prior to the installation of ...
The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation
We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We have obtained accurate radial velocities ...

The Properties of Microjansky Radio Sources in the HDF-N, SSA13, and SSA22 Fields
(abridged) We present multiwavelength observations for a large sample of microjansky radio sources detected in ultradeep 1.4GHz maps centered on the Hubble Deep Field-North (HDF-N) and the Hawaii Survey Fields SSA13 and ...
The Infrared Array Camera component of the Spitzer Space Telescope Extragalactic First Look Survey
We present Infrared Array Camera (IRAC) data and source catalogs from the Spitzer Space Telescope Extragalactic First Look Survey. The data were taken in four broad bands centered at nominal wavelengths of 3.6, 4.5, 5.8 ...
Energetic galaxy-wide outflows in high-redshift ultra-luminous infrared galaxies hosting AGN activity
We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs) that host Active Galactic Nuclei (AGN) ...
First results from the UBC etch-alignment mosaic CCD
First imaging results are obtained with a new CCD mosaic prototype (3K x 3k, 15 \mu m pixels). The CCDs are aligned using an etched socket alignment technique. Three different measurements of the alignment are made using ...
