VAST - An ASKAP Survey for Variables and Slow Transients is a Survey Science Project for the Australian SKA Pathfinder.
ASKAP will give us an unprecedented opportunity to investigate the transient sky at radio wavelengths. Its wide-field survey capabilities will enable the discovery and investigation of variable and transient phenomena from the local to the cosmological, including flare stars, intermittent pulsars, X-ray binaries, magnetars, extreme scattering events, intra-day variables, radio supernovae and orphan afterglows of gamma ray bursts.
In addition ASKAP probes unexplored regions of phase space where new classes of transient sources may be detected. We plan to run a comprehensive program based on a multi-tiered survey strategy to characterise the radio transient sky through detection and monitoring of transient and variable sources.
The science goals for our survey are:
