Welcome

The Widefield ASKAP L-band Legacy All-sky Blind surveY (or WALLABY) is one of two key surveys that are now running on the Australian SKA Pathfinder (ASKAP), which is an innovative imaging radio telescope located in an extremely radio quiet zone (the Murchison Radio-astronomy Observatory) in Western Australia. The aim of WALLABY is to use the powerful widefield phased-array technology of ASKAP to observe three-quarters of the whole sky in the 21-cm line of neutral hydrogen (or HI) at 30-arcsec resolution, thereby detecting and imaging the gas distribution in hundreds of thousands of external galaxies in the local Universe. This will allow astronomers to gain a much improved understanding of the processes involved in galaxy formation and evolution, and the role of stellar and black hole feedback, gas accretion and galaxy interactions in these processes. Currently, WALLABY has entered the Pilot Survey phase and has imaged three 60 square degree fields around nearby galaxy clusters with the full ASKAP-36 array, as well as a number of early science fields with smaller numbers of antennas. Full WALLABY is expected to start in 2021.
