SMGPS Great Attractor HI galaxy catalogue
Listed in IVOA Registry (Virtual Observatory)
This paper presents the first HI results extracted from the South African Radio Astronomy Observatory (SARAO) MeerKAT Galactic Plane Survey (SMGPS) - a narrow strip (|b|<1.5deg) along the southern Milky Way.
Description
The primary goal consisted in tracing the great attractor (GA) wall across the innermost zone of avoidance. We reduced a segment spanning the longitude range 302deg<l<332deg for the redshift range z < 0.08.
The superb SMGPS sensitivity (rms=0.3-0.5mJy/beam- per 44km/s channel) and angular resolution (~31"x26") lead to a detection limit of log(MHI/M_{sun}_)<8.5 at the GA distance (Vhel~3500-6500km/s). A total of 477 galaxy candidates were identified over the full redshift range. A comparison of the few HI detections with counterparts in the literature (mostly HIZOA) found the HI fluxes and other HI parameters to be highly consistent.

The continuation of the GA wall is confirmed through a prominent overdensity of N=214 detections in the GA distance range. At higher latitudes, the wall moves to higher redshifts, supportive of a possible link with the Ophiuchus cluster located behind the Galactic Bulge. This deep interferometric HI survey demonstrates the power of the SMGPS in improving our insight of large-scale structures at these extremely low latitudes, despite the high obscuration and continuum background.
