TL;DR
This survey used the Westerbork Synthesis Radio Telescope to map a galaxy overdensity behind the Milky Way, resulting in a catalogue of 211 HI-detected galaxies and insights into the structure of the Perseus-Pisces filament.
Contribution
First wide-field HI imaging survey of the Zone-of-Avoidance crossing the Perseus-Pisces filament, providing detailed HI catalogues and maps of galaxies in this obscured region.
Findings
Detected 211 galaxies with HI emission, 62% with near-infrared counterparts.
Identified galaxy structures associated with the Perseus-Pisces Supercluster and a secondary overdensity.
Mapped the HI properties and velocity fields of galaxies in a previously underexplored region.
Abstract
We present results of a blind 21cm HI-line imaging survey of a galaxy overdensity located behind the Milky Way at 160 deg, 0.5 deg. 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 (3C129) 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 sq.deg using the Westerbork Synthesis Radio Telescope in a hexagonal mosaic of 35 pointings observed for 12 hours each, in the radial velocity range km/s. The survey has a sensitivity of 0.36 mJy/beam rms at a velocity resolution of 16.5 km/s. We detected 211 galaxies, 62% of which have a near-infrared counterpart in the UKIDSS Galactic Plane…
