Scuba Local Universe Galaxy Survey

Scientific paper

We present new results from the SCUBA Local Universe Galaxy Survey (SLUGS), the first large statistical submillimetre survey of the local Universe. Following our initial survey of a sample of 104 IRAS-selected galaxies we now present the results of a sample of 80 Optically-Selected galaxies. This new sample, by definition free from temperature selection effects, allows us for the first time to determine how the amount of cold dust in galaxies varies with Hubble type. We detect 6 ellipticals in the sample and find them to have dust masses in excess of 107Msolar. We derive local submillimetre Luminosity Functions and Dust Mass Functions, both directly for the Optically-Selected SLUGS and by extrapolation from the IRAS PSCz survey, and find excellent agreement.
