MeerKAT 1.28GHz obs. of IRAS RBGS galaxies
Listed in IVOA Registry (Virtual Observatory)
The IRAS Revised Bright Galaxy Sample (RBGS) comprises galaxies and unresolved mergers stronger than S=5.24Jy at {lambda}=60{mu}m with Galactic latitudes |b|>5{deg}.
Description
Nearly all are dusty star-forming galaxies whose radio continuum and far-infrared luminosities are proportional to their current rates of star formation. We used the MeerKAT array of 64 dishes to make 5x3min snapshot observations at {nu}=1.28GHz covering all 298 southern (DEJ2000<0{deg}) RBGS sources identified with external galaxies.
The resulting images have {theta}~7.5" FWHM resolution and rms fluctuations {sigma}~20{mu}Jy/beam~0.26K low enough to reveal even faint disk emission. The rms position uncertainties are {sigma}_{alpha}_~{sigma}_{delta}_~1" relative to accurate near-infrared positions, and the image dynamic ranges are DR>~10^4^:1.
