Abstract:
A redshift survey of galaxies located in the direction of the southern
Milky Way has been carried out using the FLAIR multi-objects system on
the 1.2-m UK Schmidt Telescope (UKST) at the Anglo-Australian
Observatory in Australia. The galaxy sample was extracted from the
LEDA (http://www-obs.univ-lyon1.fr/base/) and COSMOS (Cat.
J/A+AS/117/519) data bases but essentially by scanning by eye four
plates of the UKST/SERC Survey in the region between the Centaurus
complex and the Pavo-Indus (PI) wall. The galaxies selected have high
central surface brightnesses and are distributed evenly over the whole
search area. The majority of the galaxies have apparent magnitudes in
the range 11.5<BJ<17. Redshifts were determined for 211 galaxies
with one additional object being found to be Galactic - a planetary
nebula. A highly significant density enhancement is found in the
galaxy distribution at 5000km/s or 67Mpc (H0=75km/s/Mpc). This
suggests that a connection exists between the Centaurus complex and
the PI wall across the zone of avoidance (ZOA) associated with the
Milky Way and as such could be one of the larger structures in the
nearby Universe.
