Exploring the Dynamic Radio Sky with ASKAP/VAST

 

Abstract

The Variables and Slow Transients Survey (VAST) on the Australian SKA Pathfinder (ASKAP) is designed to detect highly variable and transient radio sources on timescales from 5 s to 5 yr. We present the survey description and observation strategy, with observations of ~2000 deg^2 of the Galactic plane every two weeks and ~10,000 deg^2 of the high-latitude sky every two months, allowing identification of new and rare classes of transients. We show select results from the first few years of survey data, focusing on polarized Galactic sources such as flaring stars, new pulsars, Galactic Center transients, and long-period radio transients.

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
