Scientific paper

The Millennium Galaxy Catalogue (MGC) provides a structural database comprising 10,095 well resolved galaxies drawn from a 37.5 sq. deg region of sky, with $B_{\tiny \sc mgc} < 20.0$ mag and 96.1 per cent spectroscopic completeness. The data are being used to investigate a number of diverse topics including: the nearby galaxy merger rate (via close pairs and asymmetry); dust attenuation; bulge and disc luminosity functions; the luminosity size relations; the supermassive black hole mass function; galaxy bimodality; the space-density of high and low surface brightness galaxies; blue spheroids; and the total $B$-band luminosity function. Plans to extend the MGC in area (200 sq. deg), depth ($K_{Vega}=16.5$ mag), resolution (0.5$''$) and wavelength $(u-K)$ are underway.
