Summary of Programme

The primary objective of the Millennium Galaxy Survey (MGC) is to define a complete and local galaxy catalogue which encompasses a homogeneous volume (V approximately 100h¯³ Mpc³) for all galaxy types down to 0.01L(star).

The catalogue, MGC-bright, will contain fluxes (B, V, R & I), colours, morphologies (i.e. equivalent to HST-quality for faint galaxies), surface brightnesses, scale-lengths, ellipticities, orientations and accurate astrometry for about 10,000 galaxies. MGC-bright will be used to characterise the distribution of the stuctural properties of the local galaxy population. In addition the same dataset will be used to construct three further catalogues: MGC-faint, MGC-LSGB and MGC-cluster.

MGC-faint will provide an excellent resource containing about 5 million objects from which survey samples can be drawn for future exploitation with large telescopes. MGC-faint will contain flux (b(J) < 25), colour, mean surface brightness, axis-ratio and position information.

MGC-LSBG will define a sample of low surface brightness galaxies selected according to well defined size and surface brightness limits (alpha > 2" & µ < 26 B mags per square arcsec); and the MGC-Cluster will identify a homogeneous distant cluster sample.

In addition the survey area will be centred on the equatorial 2dF Galaxy Redshift Survey (GRS) strip (yielding redshifts to b(J) = 19.5) and will significantly value-add to the science return of these surveys. The charaterisation of the local field population is of fundamental improtance to the understanding of the evolution of the galaxy population and the interpretaion of deep images.
