Abstract:
The Herschel Fornax Cluster Survey is a deep, far-infrared (FIR)
survey of the Fornax cluster. The survey is in five Herschel
bands (100-500µm) and covers an area of 16deg2 centred on
NGC 1399. This paper presents photometry, detection rates, dust
masses, and temperatures using an optically selected sample from the
Fornax Cluster Catalogue. Our results are compared with those
previously obtained using data from the Herschel Virgo Cluster
Survey (HeViCS). In Fornax, we detect 30 of the 237 (13%)
optically selected galaxies in at least one Herschel band. The
global detection rates are significantly lower than Virgo, reflecting
the morphological make up of each cluster - Fornax has a lower
fraction of late-type galaxies. For galaxies detected in at least
three bands, we fitted a modified blackbody with a β=2
emissivity. Detected early-type galaxies (E/S0) have a mean dust mass,
temperature, and dust-to-stars ratio of
log10(<Mdust>/M☉)=5.82±0.20, <Tdust≥20.82±1.77K, and
log10(Mdust/Mstars)=-3.87±0.28, respectively. Late-type
galaxies (Sa to Sd) have a mean dust mass, temperature, and
dust-to-stars ratio of log10(Mdust>/M☉)=6.54±0.19,
<Tdust≥17.47±0.97K, and log10(Mdust/Mstars)=-2.93±0.09,
respectively. The different cluster environments seem to have had
little effect on the FIR properties of the galaxies and so we conclude
that any environment-dependent evolution has taken place before the
cluster was assembled.
