Description
We present colour-colour diagrams of detected sources in the
Herschel-ATLAS science demonstration field from 100 to 500 μm using
both PACS and SPIRE. We fit isothermal modified black bodies to the
spectral energy distribution (SED) to extract the dust temperature of
sources with counterparts in Galaxy And Mass Assembly (GAMA) or SDSS
surveys with either a spectroscopic or a photometric redshift. For a
subsample of 330 sources detected in at least three FIR bands with a
significance greater than 3σ, we find an average dust temperature
of (28±8) K. For sources with no known redshift, we populate the
colour-colour diagram with a large number of SEDs generated with a broad
range of dust temperatures and emissivity parameters, and compare to
colours of observed sources to establish the redshift distribution of
this sample. For another subsample of 1686 sources with fluxes above 35
mJy at 350 μm and detected at 250 and 500 μm with a significance
greater than 3σ, we find an average redshift of 2.2±0.6.
Herschel is an ESA space observatory with science instruments provided
by European-led Principal Investigator consortia and with important
participation from NASA.
