The Herschel Multi-Tiered Extragalactic Survey: SPIRE-mm Photometric Redshifts
We investigate the potential of submm-mm and submm-mm-radio photometric redshifts using a sample of mm-selected sources as seen at 250, 350 and 500 {\mu}m by the SPIRE instrument on Herschel. From a sample of 63 previously ... -
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 ... -
A Herschel view of the far-infrared properties of submillimetre galaxies
We study a sample of 61 submillimetre galaxies (SMGs) selected from ground-based surveys, with known spectroscopic redshifts and observed with Herschel as part of the PACS Evolutionary Probe (PEP) and the Herschel Multi-tiered ... -
Herschel-PACS observations of [OI]63um towards submillimetre galaxies at z 1
We present Herschel-PACS spectroscopy of the [OI]63um far-infrared cooling line from a sample of six unlensed and spectroscopically-confirmed 870um-selected submillimetre (submm) galaxies (SMGs) at 1.13, tentatively detect ... -
Herschel-SPIRE, Far-Infrared Properties of Millimetre-Bright and -Faint Radio Galaxies
(abridged) We present the first study of the farIR properties of high redshift, radio-selected ULIRGs using deep observations obtained with SPIRE from the Herschel Multi-tiered Extragalactic Survey (HerMES). These galaxies ... -
High-resolution CO and radio imaging of ULIRGs: extended CO structures, and implications for the universal star formation law
We present high spatial resolution (0.4", ~3.5 kpc) PdBI interferometric data on three ultra-luminous infrared galaxies (ULIRGs) at z~2: two submillimetre galaxies and one submillimetre faint star forming radio galaxy. The ... -
High-resolution Millimeter Imaging of Submillimeter Galaxies
We present sub-arcsecond resolution IRAM PdBI interferometry of eight submillimeter galaxies at redshifts from 2 to 3.4, where we detect continuum at 1mm and/or CO lines at 3 and 1 mm. The CO 3-2/4-3 line profiles in five ... -
An HST/ACS View of the Inhomogeneous Outer Halo of M31
We present a high precision photometric view of the stellar populations in the outer halo of M31, using data taken with the Hubble Space Telescope Advanced Camera for Surveys (HST/ACS). We analyse the field populations ... -
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 Hubble Space Telescope GOODS NICMOS Survey: Overview and the Evolution of Massive Galaxies at 1.5 < z < 3
We present the details and early results from a deep near-infrared survey utilising the NICMOS instrument on the Hubble Space Telescope centred around massive M_* > 10^11 M_0 galaxies at 1.7 10^11 M_0, whereby we find an ... -
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 ... -
A Hubble Space Telescope NICMOS and ACS Morphological Study of z~2 Submillimetre Galaxies
We present a quantitative morphological analysis using HST NICMOS H160- and ACS I775- band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which have redshifts between z=0.7-3.4. Our analysis also ... -
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 ... -
The Infrared Counterparts of the Optically Unidentified CDF-S 1Ms Sources
The Chandra Deep Field South (CDF-S) 1Ms exposure produced a catalog of 346 X-ray sources, of which 59 were not visible on the VLT/FORS1 and the ESO-MPI/WFI deep R-band images to a limit of R_{vega}=26.1--26.7 mag. Using ... -
Infrared Properties of Radio-Selected Submillimeter Galaxies in the Spitzer First Look Survey Verification Field
We report on submillimeter and infrared observations of 28 radio-selected galaxies in the Spitzer First Look Survey Verification field (FLSV). All of the radio-selected galaxies that show evidence for emission at 850um ... -
Inside the whale: the structure and dynamics of the isolated Cetus dwarf spheroidal
This paper presents a study of the Cetus dwarf, an isolated dwarf galaxy within the Local Group. A matched-filter analysis of the INT/WFC imaging of this system reveals no evidence for significant tidal debris that could ... -
Integral Field Spectroscopy of 2.0<z<2.7 Sub-mm Galaxies; gas morphologies and kinematics
We present two-dimensional, integral field spectroscopy covering the rest-frame wavelengths of strong optical emission lines in nine sub-mm-luminous galaxies (SMGs) at 2.0<z<2.7. The GEMINI-NIFS and VLT-SINFONI imaging ... -
Interferometric CO Observations of submillimeter-faint, radio-selected starburst galaxies at z~2
High-redshift, dust-obscured galaxies -- selected to be luminous in the radio but relatively faint at 850um -- appear to represent a different population from the ultra-luminous submillimeter- (submm-) bright population. ... -
