First results of sub-arcsecond scale objects identified with ASKAP using interplanetary scintillation

R. Chhetri, J. S. Morgan, R. D. Ekers +4

We present a catalogue of 131 compact sources detected at 823 MHz via their Interplanetary Scintillation (IPS). These measurements were made with the ASKA…

Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogues

A. Waszewski, J. S. Morgan, M. C. M. Cheung +6

We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient eve…

A new long period radio transient: Discovery of pulses repeating every 1.16 hours from ASKAP J175534.9-252749.1

Samuel J. McSweeney, Natasha Hurley-Walker, Csanád Horváth +7

We report the discovery of several new pulses from the source ASKAP J175534.9-252749.1 (J1755-2527), originally identified from a single 2-min long pulse, confirming it as a long p…

Latitudinal dependence of the solar wind during periods of high and low activity through interplanetary scintillation

A. Waszewski, J. S. Morgan, R. Ekers +5

We present a study of the solar wind over different periods of the solar cycle, specifically focussing on the minimum between solar cycles 24 and 25, and the active, ascending phas…

Resolving moving heliospheric structures using interplanetary scintillation observations with the Murchison Widefield Array

A. Waszewski, J. S. Morgan, R. Chhetri +4

We have conducted a blind search in 49 consecutive days of interplanetary scintillation observations made by the Murchison Widefield Array from mid-2019, with overlapping daily obs…

Detection and Characterisation of a Coronal Mass Ejection using Interplanetary Scintillation measurements from the Murchison Widefield Array

J. Morgan, P. I. McCauley, A. Waszewski +2

We have shown previously that the Murchison Widefield Array (MWA), can detect hundreds of Interplanetary Scintillation (IPS) sources simultaneously across a field of view $\sim30^\…

A measurement of small-scale features using ionospheric scintillation. Comparison with refractive shift measurements

A. Waszewski, J. Morgan, C. H. Jordan

We present a study of scintillation induced by the mid-latitude ionosphere. By implementing methods currently used in Interplanetary Scintillation studies to measure amplitude scin…
