Some ASKAP Info

ASKAP is the "Australian SKA Pathfinder". As ASKAP design and software are progressing rapidly, we have assembled international science teams who will carry out survey design studies, liase with the software team, explore the sky via cosmological simulations and write many excellent papers. The ASKAP HI All-Sky Survey (nick-named WALLABY) is the top-ranked spectral line survey.

ASKAP will consist of 36 x 12-m antennas (4072 sq m) with focal plane arrays providing a field-of-view (FOV) of 5.5 deg x 5.5 deg (= 30 sq deg) operating in the range 0.7 - 1.8 GHz, i.e. ideal for large HI and 20-cm continuum surveys. The inner 30 antennas (3400 sq m) of ASKAP are optimally arranged in a 2-km configuration, delivering an angular resolution of 30". A further six antennas will be placed at larger distances (max. baseline = 6-km), giving an excellent angular resolution of around 10".

The first ASKAP antenna arrived on site in December 2009. The picture below shows the fully assembled antenna on its pad in Western Australia.
