    • Astrometric accuracy of snapshot fast radio burst localisations with ASKAP
      Day, C.K.; Deller, A.T.; James, Clancy ; Lenc, E.; Bhandari, S.; Shannon, Ryan ; Bannister, K.W. (2021)
      The recent increase in well-localised fast radio bursts (FRBs) has facilitated in-depth studies of global FRB host properties, the source circumburst medium, and the potential impacts of these environments on the burst ...
    • A census of baryons in the Universe from localized fast radio bursts
      Macquart, Jean-Pierre ; Prochaska, J.X.; McQuinn, M.; Bannister, K.W.; Bhandari, S.; Day, C.K.; Deller, A.T.; Ekers, Ronald ; James, Clancy ; Marnoch, L.; Osłowski, S.; Phillips, C.; Ryder, S.D.; Scott, D.R.; Shannon, Ryan ; Tejos, N. (2020)
      More than three-quarters of the baryonic content of the Universe resides in a highly diffuse state that is difficult to detect, with only a small fraction directly observed in galaxies and galaxy clusters1,2. Censuses of ...
    • A population analysis of pulse broadening in ASKAP fast radio bursts
      Qiu, H.; Shannon, Ryan ; Farah, W.; Macquart, Jean-Pierre ; Deller, A.T.; Bannister, K.W.; James, Clancy ; Flynn, C.; Day, C.K.; Bhandari, S.; Murphy, T. (2020)
      The pulse morphology of fast radio bursts (FRBs) provides key information in both understanding progenitor physics and the plasma medium through which the burst propagates. We present a study of the profiles of 33 bright ...
    • The fast radio burst dispersion measure distribution
      Arcus, W.R.; Macquart, Jean-Pierre ; Sammons, M.W.; James, Clancy ; Ekers, Ronald (2021)
      We compare the dispersion measure (DM) statistics of FRBs detected by the ASKAP and Parkes radio telescopes. We jointly model their DM distributions, exploiting the fact that the telescopes have different survey fluence ...
    • A single fast radio burst localized to a massive galaxy at cosmological distance
      Bannister, K.W.; Deller, A.T.; Phillips, C.; Macquart, Jean-Pierre ; Prochaska, J.X.; Tejos, N.; Ryder, S.D.; Sadler, E.M.; Shannon, Ryan ; Simha, S.; Day, C.K.; McQuinn, M.; North-Hickey, F.O.; Bhandari, S.; Arcus, W.R.; Bennert, V.N.; Burchett, J.; Bouwhuis, M.; Dodson, R.; Ekers, Ronald ; Farah, W.; Flynn, C.; James, Clancy ; Kerr, M.; Lenc, E.; Mahony, E.K.; O'Meara, J.; Osłowski, S.; Qiu, H.; Treu, T.; U, V.; Bateman, T.J.; Bock, D.C.J.; Bolton, R.J.; Brown, A.; Bunton, J.D.; Chippendale, A.P.; Cooray, F.R.; Cornwell, T.; Gupta, N.; Hayman, D.B.; Kesteven, M.; Koribalski, B.S.; MacLeod, A.; McClure-Griffiths, N.M.; Neuhold, S.; Norris, R.P.; Pilawa, M.A.; Qiao, R.Y.; Reynolds, J.; Roxby, D.N.; Shimwell, T.W.; Voronkov, M.A.; Wilson, C.D. (2019)
      Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some are known to repeat, but most are single bursts. Nonrepeating FRB observations have had insufficient positional accuracy to localize ...
    • The Spectral Properties of the Bright Fast Radio Burst Population
      Macquart, Jean-Pierre ; Shannon, Ryan ; Bannister, K.W.; James, Clancy ; Ekers, Ronald ; Bunton, J.D. (2019)
      We examine the spectra of 23 fast radio bursts (FRBs) detected in a fly's-eye survey with the Australian SKA Pathfinder, including those of three bursts not previously reported. The mean spectral index of α = -1.5 -0.3+0.2 ...
    • Spectropolarimetric Analysis of FRB 181112 at Microsecond Resolution: Implications for Fast Radio Burst Emission Mechanism
      Cho, H.; Macquart, Jean-Pierre ; Shannon, Ryan ; Deller, A.T.; Morrison, Ian ; Ekers, Ronald ; Bannister, K.W.; Farah, W.; Qiu, H.; Sammons, M.W.; Bailes, M.; Bhandari, S.; Day, C.K.; James, Clancy ; Phillips, C.J.; Prochaska, J.X.; Tuthill, J. (2020)
      We have developed a new coherent dedispersion mode to study the emission of fast radio bursts (FRBs) that trigger the voltage capture capability of the Australian SKA Pathfinder (ASKAP) interferometer. In principle the ...
    • Limits on Precursor and Afterglow Radio Emission from a Fast Radio Burst in a Star-forming Galaxy
      Bhandari, S.; Bannister, K.W.; Lenc, E.; Cho, H.; Ekers, Ronald ; Day, C.K.; Deller, A.T.; Flynn, C.; James, Clancy ; Macquart, Jean-Pierre ; Mahony, E.K.; Marnoch, L.; Moss, V.A.; Phillips, C.; Prochaska, J.X.; Qiu, H.; Ryder, S.D.; Shannon, Ryan ; Tejos, N.; Wong, O.I. (2020)
      We present a new fast radio burst (FRB) at 920 MHz discovered during commensal observations conducted with the Australian Square Kilometre Array Pathfinder (ASKAP) as part of the Commensal Real-time ASKAP Fast Transients ...
    • Chronicling the Host Galaxy Properties of the Remarkable Repeating FRB 20201124A
      Fong, W.F.; Dong, Y.; Leja, J.; Bhandari, S.; Day, C.K.; Deller, A.T.; Kumar, P.; Prochaska, J.X.; Scott, D.R.; Bannister, K.W.; Eftekhari, T.; Gordon, A.C.; Heintz, K.E.; James, Clancy ; Kilpatrick, C.D.; Mahony, E.K.; Rouco Escorial, A.; Ryder, S.D.; Shannon, Ryan ; Tejos, N. (2021)
      We present the Australian Square Kilometre Array Pathfinder localization and follow-up observations of the host galaxy of the repeating fast radio burst (FRB) source, FRB 20201124A, the fifth such extragalactic repeating ...
    • Nature of radio-wave radiation from particle cascades
      James, Clancy (2022)
      The nature of the radio-wave radiation generated by particle cascades in both the Earth's atmosphere and dense media such as ice has, historically, been much debated. This situation changed in 2010, with the community ...
