| dc.description.abstract | The Widefield ASKAP L-band Legacy All-sky
Blind surveY (WALLABY) is a next-generation survey
of neutral hydrogen (H I) in the Local Universe. It uses
the widefield, high-resolution capability of the Australian
Square Kilometer Array Pathfinder (ASKAP), a radio interferometer
consisting of 36 × 12-m dishes equipped with
Phased-Array Feeds (PAFs), located in an extremely radioquiet
zone in Western Australia. WALLABY aims to survey
three-quarters of the sky (−90◦
< δ <+30◦) to a redshift of
z 0.26, and generate spectral line image cubes at ∼30 arcsec
resolution and ∼1.6 mJy beam−1 per 4 kms−1 channel
sensitivity. ASKAP’s instantaneous field of view at 1.4 GHz,
delivered by the PAF’s 36 beams, is about 30 sq deg. At
an integrated signal-to-noise ratio of five, WALLABY is expected
to detect around half a million galaxies with a mean
redshift of z ∼ 0.05 (∼200 Mpc). | en_US |
