A search for long-timescale, low-frequency radio transients
Tara Murphy, David L. Kaplan, Steve Croft +30
We present a search for transient and highly variable sources at low radio frequencies (150-200 MHz) that explores long timescales of 1-3 years. We conducted this search by compari…
The magnetic field and turbulence of the cosmic web measured using a brilliant fast radio burst
V. Ravi, R. M. Shannon, M. Bailes +13
Fast radio bursts (FRBs) are millisecond-duration events thought to originate beyond the Milky Way galaxy. Uncertainty surrounding the burst sources, and their propagation through…
A deep / wide 1-2 GHz snapshot survey of SDSS Stripe 82 using the Karl G. Jansky Very Large Array in a compact hybrid configuration
I. Heywood, M. J. Jarvis, A. J. Baker +9
We have used the Karl G. Jansky Very Large Array to image ~100 sq. deg. of SDSS Stripe 82 at 1-2 GHz. The survey consists of 1,026 snapshot observations of 2.5 minutes duration, us…
Recent Developments in Measuring Signal and Noise in Phased Array Feeds at CSIRO
A. P. Chippendale, D. McConnell, K. Bannister +6
We describe recent developments in measuring both signal and noise in phased array feeds for radio astronomy at CSIRO. We introduce new techniques including aperture array noise me…
Real-time detection of an extreme scattering event: constraints on Galactic plasma lenses
Keith W. Bannister, Jamie Stevens, Artem V. Tuntsov +4
Extreme scattering events (ESEs) are distinctive fluctuations in the brightness of astronomical radio sources caused by occulting plasma lenses in the interstellar medium. The infe…
Wide-field broadband radio imaging with phased array feeds: a pilot multi-epoch continuum survey with ASKAP-BETA
I. Heywood, K. W. Bannister, J. Marvil +45
The Boolardy Engineering Test Array is a 6 x 12 m dish interferometer and the prototype of the Australian Square Kilometre Array Pathfinder (ASKAP), equipped with the first generat…
