The SCUBA Local Universe Galaxy Survey — I. First measurements of the submillimetre luminosity and dust mass functions
This is the first of a series of papers presenting results from the SCUBA Local Universe Galaxy Survey (SLUGS), the first statistical survey of the submillimetre properties of the local Universe. As
The Primordial helium abundance from observations of extragalactic H-II regions
The pre-galactic (assumed primordial) helium mass fraction Y p is determined to be 0.228 ± 0.005 (s.e.) or Y p < 0.242 with 95 per cent confidence, taking reasonably likely systematic errors into
SCUBA observations of galaxies with metallicity measurements: a new method for determining the relation between submillimetre luminosity and dust mass
Using a new technique, we have determined a value for the constant of proportionality between submillimetre emission and dust mass, the dust mass‐absorption coefficient (κd) at 850 µm. Our method has
On the Cosmic Origins of Carbon and Nitrogen
The behaviour of C/O and N/O ratios as a function of metallicity in HII regions in galaxies is characterised, and used to derive rough values of chemical yields from analytic models. These ‘analytic
On the composition of H II regions in southern galaxies. III. NGC 2997 and 7793.
On a obtenu des spectres AAT/IPCS pour une partie de la region nucleaire et pour quatre regions HII dans la galaxie SABc NGC 2997, et pour le noyau et cinq regions HII dans la galaxie prototype Sd du
Dust formation in early galaxies
We investigate the sources and amount of dust in early galaxies. We discuss dust nucleation in stellar atmospheres using published extended atmosphere models, stellar evolution tracks and nucleation
A Census of Metals at High and Low Redshift and the Connection Between Submillimetre Sources and Spheroid Formation
Deep surveys in many wavebands have shown that the rate at which stars were forming was at least a factor of 10 higher at redshifts >1 than today. Heavy elements (‘metals’) are produced by stars, and
The relation between abundance gradients and the physical properties of spiral galaxies
Some correlations of the behaviour of chemical abundance gradients with other physical properties of spiral galaxies are established. The sample is some 30 galaxies for which good published
Type II supernovae as a significant source of interstellar dust
The detection of ∼2–4M[circdot] of cold dust in the youngest known Galactic supernova remnant, Cassiopeia A, implies that supernovae are at least as important as stellar winds in producing dust in the authors' Galaxy and would have been the dominant source of dust at high redshifts.
