SPIRE imaging of M 82 : Cool dust in the wind and tidal streams
(2010-07-01)
M 82 is a unique representative of a whole class of galaxies, starbursts with superwinds, in the Very Nearby Galaxy Survey with Herschel. In addition, its interaction with the M 81 group has stripped a significant portion ...
Herschel-SPIRE observations of the disturbed galaxy NGC 4438
(2010-07-01)
We present Herschel-SPIRE observations of the perturbed galaxy NGC 4438 in the Virgo cluster. These images reveal the presence of extra-planar dust up to ~4–5 kpc away from the galaxy's disk. The dust closely follows the ...
HerMES: Halo occupation number and bias properties of dusty galaxies from angular clustering measurements
(2010-07-01)
We measure the angular correlation function, w(θ), from 0.5 to 30 arcmin of detected sources in two wide fields of the Herschel Multi-tiered Extragalactic Survey (HerMES). Our measurements are consistent with the expected ...
Herschel photometric observations of the low metallicity dwarf galaxy NGC 1705
(2010-07-01)
We present Herschel SPIRE and PACS photometeric observations of the low metallicity (Z ~ 0.35ΖΘ ) nearby dwarf galaxy, NGC 1705, in six wavelength bands as part of the Dwarf Galaxy Survey guaranteed time Herschel key ...
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 ...
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 ...
