Abstract:
The Sloan Digital Sky Survey (SDSS) has created a knowledge gap
between the Northern and the Southern hemispheres, which is very
marked for white dwarfs: Only ∼15 per cent of the known white
dwarfs are south of the equator. Here, we make use of the VLT Survey
Telescope (VST) ATLAS survey, one of the first surveys obtaining deep,
optical, multiband photometry over a large area of the southern skies,
to remedy this situation. Applying the colour and proper-motion
selection developed in our previous work on SDSS to the most recent
internal data release (2016 April 25) of VST ATLAS, we created a
catalogue of ∼4200 moderately bright (g≤19), high-confidence
southern white dwarf candidates, which can be followed up individually
with both the large array of southern telescopes or in bulk with ESO's
forthcoming multi-object spectrograph 4MOST.
Description:
VST ATLAS is primarily a cosmology-focused survey aiming to image
4700deg2 of the Southern Sky at high galactic latitudes (|b|>30°)
in five bands (ugriz) to comparable depths to the SDSS in the north.
