ARKS is a wide and deep VISTA public survey over the SGP and GAMA
-ATLAS) http://www.h-atlas.org/ fields in the Ks
~ 300deg sq. to a 5-sigma depth of Ks
~ 22.7 magAB in 1,200 hours.
The fields in SH
ARKS have been and will be covered by a number of
future deep and/or wide far-IR and radio surveys.
Our motivations are:
- To provide the best possible counterpart identification for ~ 90 % of the sources detected at 0 < z < 3 by H-ATLAS, ASKAP, SKA and LOFAR
- To produce a sample of a thousand strong lenses for cosmography studies.
- To study the evolution of the most massive structures in the Universe..
The depth of the deepest available observations over the proposed fields
(VIKING survey, 5sigmaKs
< 21.2 magAB) is not enough to accomplish
any of these aims.
The SHARKS fields will also overlap with future LSST (optical) and EUCLID
(near-IR - but not Ks
) observations, representing a perfect
complementary dataset with an enormous legacy.
