Measures of star formation rates from infrared (Herschel) and UV (GALEX) emissions of galaxies in the HerMES fields
(2010)
The reliability of infrared (IR) and ultraviolet (UV) emissions to measure star formation rates (SFRs) in galaxies is investigated for a large sample of galaxies observed with the Spectral and Photometric Imaging Receiver ...
Herschel-ATLAS: The dust energy balance in the edge-on spiral galaxy UGC 4754
(2010)
We use Herschel PACS and SPIRE observations of the edge-on spiral galaxy UGC 4754, taken as part of the H-ATLAS SDP observations, to investigate the dust energy balance in this galaxy. We build detailed SKIRT radiative ...
The detection of a population of submillimeter-bright, strongly lensed galaxies
(2010)
Gravitational lensing is a powerful astrophysical and cosmological probe and is particularly valuable at submillimeter wavelengths for the study of the statistical and individual properties of dusty star-forming galaxies. ...
Herschel-ATLAS: Extragalactic number counts from 250 to 500 microns
(2010)
Aims. The Herschel-ATLAS survey (H-ATLAS) will be the largest area survey to be undertaken by the Herschel Space Observatory. It will cover 550 sq. deg. of extragalactic sky at wavelengths of 100, 160, 250, 350 and 500 μm ...
Herschel-ATLAS: Blazars in the science demonstration phase field
(2010)
To investigate the poorly constrained sub-mm counts and spectral properties of blazars we searched for these in the Herschel-ATLAS (H-ATLAS) science demonstration phase (SDP) survey catalog.
We cross-matched 500 μm sources ...
H-ATLAS : PACS imaging for the Science Demonstration Phase
(2010)
We describe the reduction of data taken with the PACS instrument on board the Herschel Space Observatory in the Science Demonstration Phase of the Herschel-ATLAS (H-ATLAS) survey, specifically data obtained for a 4 × 4 ...
Herschel-ATLAS: the far-infrared-radio correlation at z <0.5
(2010)
We use data from the Herschel-ATLAS to investigate the evolution of the far-infrared–radio correlation over the redshift range 0 < z < 0.5. Using the total far-infrared luminosity of all >5σ sources in the Herschel-ATLAS ...
Herschel-ATLAS: Dust temperature and redshift distribution of SPIRE and PACS detected sources using submillimetre colours
(2010)
We present colour–colour diagrams of detected sources in the Herschel-ATLAS science demonstration field from 100 to 500 μm using both PACS and SPIRE. We fit isothermal modified black bodies to the spectral energy distribution ...
A search for debris disks in the Herschel-ATLAS
(2010)
Aims. We aim to demonstrate that the Herschel-ATLAS (H-ATLAS) is suitable for a blind and unbiased survey for debris disks by identifying candidate debris disks associated with main sequence stars in the initial science ...
Deep multi-frequency radio imaging in the Lockman Hole - II : The spectral index of submillimetre galaxies
(2010-01-01)
We have employed the Giant Metre-wave Radio Telescope and the Very Large Array to map the Lockman Hole. At 610 and 1400 MHz, we reach noise levels of 15 and 6μJy beam , respectively, with well-matched resolutions (~5 ...
