Sub-mm and near-IR observations of galaxies selected at 170 microns
We present results from JCMT sub-mm observations of sources selected from the {\sl ISO} FIRBACK (Far-IR BACKground) survey, along with UKIRT near-IR imaging of a sub-sample. This gives valuable insight into the brightest ... -
Submillimeter Galaxies at z 2: Evidence for Major Mergers & Constraints on Lifetimes, IMF and CO-H2 Conversion Factor
We report sub-arcsecond resolution IRAM PdBI millimeter CO interferometry of four z~2 submillimeter galaxies (SMGs), and sensitive CO (3-2) flux limits toward three z 2 UV-/optically selected star forming galaxies. The new ... -
Submillimeter Observations of Millimeter Bright Galaxies Discovered by the South Pole Telescope
We present APEX SABOCA 350micron and LABOCA 870micron observations of 11 representative examples of the rare, extremely bright (S_1.4mm > 15mJy), dust-dominated millimeter-selected galaxies recently discovered by the South ... -
Submillimeter Observations of the Ultraluminous BAL Quasar APM 08279+5255
With an inferred bolometric luminosity of $5\times10^{15}{\rm \lsun}$, the recently identified z=3.87, broad absorption line quasar APM 08279+5255 is apparently the most luminous object currently known. As half of its ... -
Submillimetre and far-infrared spectral energy distributions of galaxies: the luminosity-temperature relation and consequences for photometric redshifts
The spectral energy distributions (SEDs) of dusty high-redshift galaxies are poorly sampled in frequency and spatially unresolved. Their form is crucially important for estimating the large luminosities of these galaxies ... -
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 ... -
A submillimetre galaxy at z=4.76 in the LABOCA survey of the Extended Chandra Deep Field South
We report on the identification of the highest redshift submm-selected source currently known: LESSJ033229.4-275619. This source was detected in the Large Apex BOlometer CAmera (LABOCA) Extended Chandra Deep Field South ... -
Submillimetre observations of a sample of broad absorption line quasars
The broad absorption line (BAL) features seen in a small fraction of quasar optical/UV spectra are attributed to bulk outflows away from the quasar core. Observational evidence suggests that dust plays a key role in these ... -
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 submm survey of Lyman-alpha haloes in the SA22 protocluster at z=3.1
We present the results from a submm survey of a sample of 23 giant Lya emitting nebulae in the overdensity at z=3.09 in the SA22 field. These objects, which have become known as Lya Blobs (LABs) have a diverse range of ... -

Surface-induced quantum density oscillations in the presence of an external magnetic field
The electron number density and spin density near the surface of a model metal, semimetal, or semiconductor are calculated in the presence of a uniform magnetic field. The magnetic field is applied in a direction perpendicular ... -
A survey of molecular gas in luminous sub-millimetre galaxies
We present the results from a survey for 12CO emission in 40 luminous sub-millimetre galaxies (SMGs), with 850um fluxes of S850 = 4 - 20 mJy, conducted with the Plateau de Bure Interferometer. We detect 12CO emission in ... -
An SZ-selected sample of the most massive galaxy clusters in the 2500-square-degree South Pole Telescope survey
The South Pole Telescope (SPT) is currently surveying 2500 deg^2 of the southern sky to detect massive galaxy clusters out to the epoch of their formation using the Sunyaev-Zel'dovich (SZ) effect. This paper presents a ...
