• #### The Hubble Deep Field North SCUBA Super-map - I. Submillimetre maps, sources and number counts ﻿

We investigate the emission of submillimetre-wave radiation from galaxies in a 165 arcmin<SUP>2</SUP> region surrounding the Hubble Deep Field North. The data were obtained from dedicated observing runs from our group and ...
• #### The SCUBA Half Degree Extragalactic Survey (SHADES) - IX. The environment, mass and redshift dependence of star formation ﻿

We present a comparison between the SCUBA (Submillimetre Common User Bolometer Array) Half Degree Extragalactic Survey (SHADES) at 450 and 850 in the Lockman Hole East with a deep Spitzer Space Telescope survey at 3.6 ...

No abstract available.
• #### A Mid-Infrared Imaging Survey of Submillimeter-Selected Galaxies with the Spitzer Space Telescope ﻿

We present <I>Spitzer</I>-IRAC and MIPS mid-IR observations of a sample of 73 radio-detected submillimeter-selected galaxies (SMGs) with spectroscopic redshifts, the largest such sample published to date. From our data, ...
• #### The SCUBA Half-Degree Extragalactic Survey - I. Survey motivation, design and data processing ﻿

The Submillimetre Common-User Bolometer Array (SCUBA) Half-Degree Extragalactic Survey (SHADES) is a major new blank-field extragalactic submillimetre (submm) survey currently underway at the James Clerk Maxwell Telescope ...
• #### A search for the submillimetre counterparts to Lyman break galaxies ﻿

We have carried out targetted sub-mm observations as part of a programme to explore the connection between the rest-frame UV and far-IR properties of star-forming galaxies at high redshift, which is currently poorly ...
• #### A Keck/DEIMOS Kinematic Study of Andromeda IX: dark matter on the smallest galactic scales ﻿

We present the results of a kinematic survey of the dwarf spheroidal satellite of M31, And-IX, which appears to be the lowest surface brightness and also the faintest galaxy (M_V = -8.3) found to date. Using Keck/DEIMOS ...
• #### Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227 ﻿

We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ...
• #### Search For Trapped Antihydrogen ﻿

We present the results of an experiment to search for trapped antihydrogen atoms with the ALPHA antihydrogen trap at the CERN Antiproton Decelerator. Sensitive diagnostics of the temperatures, sizes, and densities of the ...
• #### Adaptive optics near-IR imaging of NGC2992 - unveiling core structures related to radio figure-8 loops ﻿

We present near-IR adaptive optics, VLA radio and HST optical imaging of the nearby Seyfert galaxy NGC2992. Spiral structure and an extension to the West are traced down to the core region at the limiting resolution of our ...
• #### Submillimetre Detection of the z=2.83 Lyman-Break Galaxy, Westphal-MM8, and Implications for SCUBA2 ﻿

We present confusion limited submillimetre (submm) observations with the SCUBA camera on the JCMT of the z=2.83 Lyman-break galaxy (LBG), Westphal-MM8, reaching an 850um sensitivity even greater than that achieved in the ...
• #### B1933+503, a dusty radio quasar at z>2: implications for blank field sub-mm surveys? ﻿

We present a detailed mm-wave and optical study of the gravitational lens system B1933+503, discovered by Sykes et al.(1998) in the radio. This object is probably the most complex lens system known, with 10 lensed components ...
• #### Submillimetre sources in rich cluster fields - source counts, redshift estimates, and cooling flow limits ﻿

Recent submillimetre surveys have revealed a population of dusty, high redshift sources of great cosmological significance for understanding dust-enshrouded star formation in distant galaxies, and for determining the origin ...
• #### Understanding the nature of the optically faint radio sources and their connection to the submillimeter population ﻿

We present a sample of 43 submillimeter sources detected (at >3 sigma), drawn from our program to follow-up optically faint radio sources with SCUBA. These sources already have associated radio and in many cases optical ...
• #### The Far- and Mid-Infrared/Radio Correlations in the Spitzer Extragalactic First Look Survey ﻿

Using the SPITZER SPACE TELESCOPE and the VLA, we present the first DIRECT evidence that the well-known far-infrared/radio correlation is valid to cosmologically significant redshift. We also confirm, with improved statistics ...
• #### A kinematically selected, metal-poor stellar halo in the outskirts of M31 ﻿

We present evidence for a metal-poor, [Fe/H]$\sim-1.4$ $\sigma$=0.2 dex, stellar halo component detectable at radii from 10 kpc to 70 kpc, in our nearest giant spiral neighbor, the Andromeda galaxy. This metal-poor sample ...
• #### Hubble Space Telescope images of submillimeter sources: large, irregular galaxies at high redshift ﻿

We present new Hubble Space Telescope STIS, high-resolution optical imaging of a sample of 13 submillimeter (submm) luminous galaxies, for which the optical emission has been pinpointed either through radio-1.4 GHz or ...
