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 ... -
THE LARGE APEX BOLOMETER CAMERA SURVEY OF THE EXTENDED CHANDRA DEEP FIELD SOUTH
No abstract available. -
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 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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Strangers in the night: Discovery of a dwarf spheroidal galaxy on its first Local Group infall
We present spectroscopic observations of the AndXII dwarf spheroidal galaxy using DEIMOS/Keck-II, showing it to be moving rapidly through the Local Group (-556 km/s heliocentric velocity, -281 km/s relative to Andromeda ... -
A population of hot, dusty ultra-luminous galaxies at z~2
We report spectroscopic redshifts for 18 microJy-radio galaxies at mean redshift of z=2.2 that are faint at both submmillimeter (submm) and optical wavelengths. While the radio fluxes of these galaxies could indicate ...
