GAMA/H-ATLAS: the ultraviolet spectral slope and obscuration in galaxies
(2011-08)
We use multiwavelength data from the Galaxy And Mass Assembly (GAMA) and Herschel-ATLAS (H-ATLAS) surveys to compare the relationship between various dust obscuration measures in galaxies. We explore the connections between ...
The first release of data from the Herschel ATLAS: the SPIRE images
(2011-07)
We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science Demonstration Phase (SDP) of the Herschel Astrophysical Terahertz ...
Star-forming galaxies at z approximate to 8-9 from Hubble Space Telescope/WFC3: implications for reionization
(2011-06)
We present a search for galaxies at 7.6 < z < 9.8 using the latest Hubble Space Telescope/Wide Field Camera 3 (WFC3) near-infrared data, based on the Lyman-break technique. We search for galaxies which have large (Y - J) ...
The evolution of radio sources in the UKIDSS-DXS-XMM-LSS field
(2011-05)
We investigate the cosmic evolution of low-luminosity (L-1.4 GHz < 1025 W Hz-1 sr-1) radio sources in the XMM Large Scale Structure Survey (XMM-LSS) field. We match low-frequency-selected (610-MHz) radio sources in the ...
Galaxy and Mass Assembly (GAMA): survey diagnostics and core data release
(2011-05)
The Galaxy and Mass Assembly (GAMA) survey has been operating since 2008 February on the 3.9-m Anglo-Australian Telescope using the AAOmega fibre-fed spectrograph facility to acquire spectra with a resolution of R approximate ...
Which haloes host Herschel-ATLAS galaxies in the local Universe?
(2011-04)
We measure the projected cross-correlation between low-redshift (z < 0.5) far-infrared selected galaxies in the science demonstration phase (SDP) field of the Herschel-ATLAS (H-ATLAS) survey and optically selected galaxies ...
Evidence for a maximum jet efficiency for the most powerful radio galaxies
(2011-03)
We use new mid-infrared (mid-IR) photometry from the Spitzer Space Telescope to study the relations between low-frequency radio luminosity density L-nu 151 (MHz), mid-IR (12 mu m rest frame) luminosity nu L-nu 12 (mu m) ...
Orientation effects in quasar spectra: the broad- and narrow-line regions
(2011-03)
We use the Sloan Digital Sky Survey, along with the NRAO VLA Sky Survey and the Westerbork Northern Sky Survey to define a sample of 746 radio-loud quasars and measure their 330 MHz-1.4 GHz spectral indexes. Following ...
EMU : Evolutionary Map of the Universe
(2011)
EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ~ 10 microJy/beam) radio continuum survey of the ...
Deep spitzer observations of infrared-faint radio sources : high-redshift radio-loud active galactic nuclei?
(2011)
Infrared-faint radio sources (IFRSs) are a rare class of objects which are relatively bright at radio wavelengths but very faint at infrared and optical wavelengths. Here we present sensitive near-infrared observations of ...
