ASKAP VAST Transients Project (VAST)

The ASKAP Variables and Slow Transients survey gives us an unprecedented opportunity to investigate the sky at radio wavelengths for highly variable and transient sources on timescales as short as 5 seconds. ASKAP’s 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 the orphan afterglows of gamma-ray bursts. VAST will probe unexplored regions of phase space where new classes of transient sources may be detected

Partner Institution: University of Sydney | Project Code: L000031

The Challenge

The challenge is managing and processing the large amounts of data from ASKAP, and finding and identifying rare transient objects within those datasets.

The Solution

Developing a software pipeline to process the data and identify transients.

The Outcome

We use Pawsey to store our data, serve it to the VAST collaboration, and run our software pipeline:
