    • Study of systematics effects on the cross power spectrum of 21 cm line and cosmic microwave background using Murchison Widefield Array data
      Yoshiura, S.; Ichiki, K.; Pindor, B.; Takahashi, K.; Tashiro, H.; Trott, Cathryn (2019)
      Observation of the 21 cm line signal from neutral hydrogen during the epoch of reionization is challenging due to extremely bright Galactic and extragalactic foregrounds and complicated instrumental calibration. A reasonable ...
    • The First Large Absorption Survey in H i (FLASH): I. Science goals and survey design
      Allison, J.R.; Sadler, E.M.; Amaral, A.D.; An, T.; Curran, S.J.; Darling, J.; Edge, A.C.; Ellison, S.L.; Emig, K.L.; Gaensler, B.M.; Garratt-Smithson, L.; Glowacki, Marcin ; Grasha, K.; Koribalski, B.S.; Lagos, C.D.P.; Lah, P.; Mahony, E.K.; Mao, S.A.; Morganti, R.; Moss, V.A.; Pettini, M.; Pimbblet, K.A.; Power, C.; Salas, P.; Staveley-Smith, L.; Whiting, M.T.; Wong, O.I.; Yoon, H.; Zheng, Z.; Zwaan, M.A. (2022)
      We describe the scientific goals and survey design of the First Large Absorption Survey in H i (FLASH), a wide field survey for 21-cm line absorption in neutral atomic hydrogen (H i) at intermediate cosmological redshifts. ...
    • Comparison of the Parkes and FAST FRB DM distribution
      Arcus, W.R.; James, Clancy ; Ekers, Ronald ; Wayth, Randall (2022)
      We model the fast radio burst (FRB) dispersion measure (DM) distribution for the Five-hundred-meter Aperture Spherical Telescope (FAST) and compare this with the four FRBs published in the literature to date. We compare ...
    • The z-DM distribution of fast radio bursts
      James, Clancy ; Prochaska, J.X.; Macquart, Jean-Pierre ; North-Hickey, F.O.; Bannister, K.W.; Dunning, A. (2022)
      We develop a sophisticated model of fast radio burst (FRB) observations, accounting for the intrinsic cosmological gas distribution and host galaxy contributions, and give the most detailed account yet of observational ...
    • Using negative-latency gravitational wave alerts to detect prompt radio bursts from binary neutron star mergers with the Murchison Widefield Array
      James, Clancy ; Anderson, Gemma ; Wen, L.; Bosveld, J.; Chu, Q.; Kovalam, M.; Slaven-Blair, T.J.; Williams, Andrew (2019)
      We examine how fast radio burst (FRB)-like signals predicted to be generated during the merger of a binary neutron star (BNS) may be detected in low-frequency radio observations triggered by the aLIGO/Virgo gravitational-wave ...
    • 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 ...
