Abstract:
We present spectral energy distributions (SEDs) for 86 Herschel
sources detected at 5σ at 250, 350 and 500um in the HerMES
SWIRE-Lockman field. We explore whether existing models for
starbursts, quiescent star-forming galaxies and active galactic
nucleus dust tori are able to model the full range of SEDs measured
with Herschel. We find that while many galaxies (∼56 per cent) are
well fitted with the templates used to fit IRAS, Infrared Space
Observatory (ISO) and Spitzer sources, for about half the galaxies two
new templates are required: quiescent ('cirrus') models with
colder (10-20K) dust and a young starburst model with higher
optical depth than Arp 220. Predictions of submillimetre fluxes based
on model fits to 4.5-24um data agree rather poorly with the
observed fluxes, but the agreement is better for fits to 4.5-70um
data. Herschel galaxies detected at 500um tend to be those with the
highest dust masses.
