Abstract:
    We have carried out a redshift survey of an IRAS flux-limited
    (f_60_>0.6) galaxy sample behind the southern Milky Way,
    210{deg}<l<360{deg} at |b|<15{deg}. The survey includes redshifts for
    951 galaxies, ~500 of which are new. Of these 951 galaxies, 462 are in
    the zone 5{deg}<b<15{deg} and 353 are in the zone -15{deg}<b<-5{deg}.
    Though the innermost region of the Milky Way (|b|=5{deg}) remains
    opaque except in the longitude near 240, the detected galaxies show a
    high degree of completeness (~70%) in the zones 5{deg}<b<15{deg} and
    -15{deg}<b<-5{deg}. The cone diagrams exhibiting the detailed
    distribution of IRAS galaxies in the region 210{deg}<l<360{deg},
    |b|<15{deg} shows two clusters in the Puppis region (l=240{deg},
    b=-7{deg}, v=2400km/s; l=245{deg}, b=-5{deg}, v=7500km/s), the A3627
    cluster (l=325{deg}, b=-7{deg}; v=4500km/s), the S4 cluster
    (l=280{deg}, b=7{deg}; v=5500km/s), and a possible void at l=245{deg},
    v=3000km/s. The region 270{deg}<l<350{deg} is dominated by overdensity
    of galaxies representing the extension of the Hydra-Centaurus complex
    in the positive latitudes and the Pavo-Indus complex in the negative
    latitudes. A velocity histogram of galaxies in the GA region
    290{deg}<l<350{deg}, |b|<15{deg}. reveals a substantial overdensity of
    galaxies in the velocity range 2400-5000km/s. The centroid of this
    overdensity is located at 4000km/s. The broad increased density of
    galaxies seen in our data corresponds with the distant concentration
    seen at 4500km/s in the supergalactic plane survey that covers the
    same longitude range like ours in l, but a larger range in latitude b
    (-30{deg} to -10{deg} and +10{deg} to +45{deg}). This lends support to
    the idea that the overdensity extends all the way from the
    Centaurus-Hydra complex (l=302{deg}, b=+22{deg}) in the north to the
    major concentration of the Pavo-Indus supercluster (l=332{deg},
    b=-24{deg}) in the south, through the Milky Way. We conclude that the
    peak of the overdensity responsible for the peculiar velocity field in
    the local region is possibly situated in the Milky Way itself.
