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.
