Abstract:
We present results of a blind 21cm HI-line imaging survey of a galaxy
overdensity located behind the Milky Way at l, b ~= 160°, 0.5°.
The overdensity corresponds to a zone-of-avoidance crossing of the
Perseus-Pisces Supercluster filament. Although it is known that this
filament contains an X-ray galaxy cluster (3C 129) hosting two strong
radio galaxies, little is known about galaxies associated with this
potentially rich cluster because of the high Galactic dust extinction.
We mapped a sky area of ∼9.6 deg2 using the Westerbork Synthesis
Radio Telescope in a hexagonal mosaic of 35 pointings observed for 12h
each, in the radial velocity range cz=2400-16600km/s. The survey has a
sensitivity of 0.36mJy/beam rms at a velocity resolution of 16.5km/s.
We detected 211 galaxies, 62 per cent of which have a near-infrared
counterpart in the UKIDSS Galactic Plane Survey. We present a
catalogue of the HI properties and an HI atlas containing total
intensity maps, position-velocity diagrams, global HI profiles and
UKIDSS counterpart images. For the resolved galaxies we also present
HI velocity fields and radial HI surface density profiles. A brief
analysis of the structures outlined by these galaxies finds that 87 of
them lie at the distance of the Perseus-Pisces Supercluster
(cz∼4000-8000km/s) and seem to form part of the 3C 129 cluster.
Further 72 detections trace an overdensity at a velocity of
cz~=10000km/s and seem to coincide with a structure predicted from
mass density reconstructions in the first 2MASS Redshift Survey.
Description:
Observations were carried out using the WSRT between 2012 August and
November. We imaged a mosaic comprising 35 fields arranged in a
hexagonal grid covering 9.6 deg2, each separated by Δ=0.5°.
The observational parameters for the 35 pointings are summarized in
Table 1.
