SED fitting of nearby galaxies in the Herschel Reference Survey
(Societe Francaise d'Astronomie et d'Astrophysique, 2010-12-01)
We compute UV to radio continuum spectral energy distributions of 51 nearby galaxies recently observed with SPIRE onboard Herschel and present infrared colours (in the 25-500 μm spectral range). SPIRE data of normal galaxies ...
The Herschel Multi-Tiered Extragalactic Survey: source extraction and cross-identifications in confusion-dominated SPIRE images
(2010-11-01)
We present the cross-identification and source photometry techniques used to process Herschel SPIRE imaging taken as part of the Herschel Multi-Tiered Extragalactic Survey (HerMES). Cross-identifications are performed in ...
On the origin of M81 group extended dust emission
(2010-11-01)
Galactic cirrus emission at far-infrared wavelengths affects many extragalactic observations. Separating this emission from that associated with extragalactic objects is both important and difficult. In this paper we discuss ...
Cold dust and young starbursts : spectral energy distributions of Herschel SPIRE sources from the HerMES survey
(2010-11-01)
We present spectral energy distributions (SEDs) for 68 Herschel sources detected at 5σ at 250, 350 and 500 μm in the HerMES SWIRE-Lockman field. We explore whether existing models for starbursts, quiescent star-forming ...
Mapping the interstellar medium in galaxies with Herschel/SPIRE
(2010-07-01)
The standard method of mapping the interstellar medium in a galaxy, by observing the molecular gas in the CO 1-0 line and the atomic gas in the 21-cm line, is largely limited with current telescopes to galaxies in the ...
Probing the molecular interstellar medium of M82 with Herschel-SPIRE spectroscopy
(2010-07-01)
We present the observations of the starburst galaxy M82 taken with the Herschel SPIRE Fourier-transform spectrometer. The spectrum (194–671 μm) shows a prominent CO rotational ladder from J = 4–3 to 13–12 emitted by the ...
HerMES: The submillimeter spectral energy distributions of Herschel/SPIRE-detected galaxies
(2010-07-01)
We present colours of sources detected with the Herschel/SPIRE instrument in deep extragalactic surveys of the Lockman Hole, Spitzer-FLS, and GOODS-N fields in three photometric bands at 250, 350 and 500 μm. We compare ...
The dust morphology of the elliptical Galaxy M 86 with SPIRE
(2010-07-01)
We present Herschel-SPIRE observations at 250–500 μm of the giant elliptical galaxy M 86 and examine the distribution of the resolved cold dust emission and its relation with other galactic tracers. The SPIRE images reveal ...
FIR colours and SEDs of nearby galaxies observed with Herschel
(2010-07-01)
We present infrared colours (in the 25–500 μm spectral range) and UV to radio continuum spectral energy distributions of a sample of 51 nearby galaxies observed with SPIRE on Herschel. The observed sample includes all ...
