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 ...
Radial distribution of gas and dust in spiral galaxies : the case of M 99 (NGC 4254) and M 100 (NGC 4321)
(2010-07-01)
By combining Herschel-SPIRE data with archival Spitzer, H i , and CO maps, we investigate the spatial distribution of gas and dust in the two famous grand-design spirals M 99 and M 100 in the Virgo cluster. Thanks to the ...
Herschel photometric observations of the nearby low metallicity irregular galaxy NGC 6822
(2010-07-01)
We present the first Herschel PACS and SPIRE images of the low-metallicity galaxy NGC 6822 observed from 70 to 500 μm and clearly resolve the H ii regions with PACS and SPIRE. We find that the ratio 250/500 is dependent ...
The Herschel Space Observatory view of dust in M81
(2010-07-01)
We use Herschel Space Observatory data to place observational constraints on the peak and Rayleigh-Jeans slope of dust emission observed at 70–500 μm in the nearby spiral galaxy M81. We find that the ratios of wave bands ...
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 ...
The central region of spiral galaxies as seen by Herschel. M 81, M 99, and M 100
(2010-07-01)
With appropriate spatial resolution, images of spiral galaxies in thermal infrared (~10 micron and beyond) often reveal a bright central component, distinct from the stellar bulge, superimposed on a disk with prominent ...
The Herschel ATLAS
(2010-05-01)
The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 570 deg2 of the extragalactic sky, 4 times larger than all the other Herschel extragalactic ...
The Herschel Reference Survey
(2010-03-01)
The Herschel Reference Survey is a Herschel guaranteed time key project and will be a benchmark study of dust in the nearby universe. The survey will complement a number of other Herschel key projects including large ...
