HerMES: SPIRE galaxy number counts at 250, 350, and 500 µm
(2010-07-01)
Emission at far-infrared wavelengths makes up a significant fraction of the total light detected from galaxies over the age of Universe. Herschel provides an opportunity for studying galaxies at the peak wavelength of their ...
First results from HerMES on the evolution of the submillimetre luminosity function
(2010-07-01)
We have carried out two extremely deep surveys with SPIRE, one of the two cameras on Herschel, at 250 μm, close to the peak of the far-infrared background. We have used the results to investigate the evolution of the ...
Herschel unveils a puzzling uniformity of distant dusty galaxies
(2010-07-01)
The Herschel Space Observatory enables us to accurately measure the bolometric output of starburst galaxies and active galactic nuclei (AGN) by directly sampling the peak of their far-infrared (IR) emission. Here we examine ...
The HerMES SPIRE submillimeter local luminosity function
(2010-07-01)
Local luminosity functions are fundamental benchmarks for high-redshift galaxy formation and evolution studies as well as for models describing these processes. Determining the local luminosity function in the submillimeter ...
HerMES: Far infrared properties of known AGN in the HerMES fields
(2010-07-01)
Nuclear and starburst activity are known to often occur concomitantly. Herschel-SPIRE provides sampling of the far-infrared (FIR) spectral energy distributions (SEDs) of type 1 and type 2 AGN, allowing for the separation ...
Herschel ATLAS: The cosmic star formation history of quasar host galaxies
(2010)
We present a derivation of the star formation rate per comoving volume of quasar host galaxies, derived from stacking analyses of far-infrared to mm-wave photometry of quasars with redshifts 0 < z < 6 and absolute I-band ...
Herschel-ATLAS: Evolution of the 250 µm luminosity function out to z = 0.5
(2010)
We have determined the luminosity function of 250 μm-selected galaxies detected in the ~14 deg2 science demonstration region of the Herschel-ATLAS project out to a redshift of z = 0.5. Our findings very clearly show that ...
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 ...
