    • 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 ...
    • Probabilistic association of transients to their hosts (PATH)
      Aggarwal, K.; Budavári, T.; Deller, A.T.; Eftekhari, T.; James, Clancy ; Prochaska, J.X.; Tendulkar, S.P. (2021)
      We introduce a new method to estimate the probability that an extragalactic transient source is associated with a candidate host galaxy. This approach relies solely on simple observables: sky coordinates and their ...
    • An Ultra-High Time Resolution Cosmic-Ray Detection Mode for the Murchison Widefield Array
      Williamson, A.; James, Clancy ; Tingay, Steven ; McSweeney, Sam ; Ord, S.M. (2021)
      The radio-wavelength detection of extensive air showers (EASs) initiated by cosmic-ray interactions in the Earth's atmosphere is a promising technique for investigating the origin of these particles and the physics of ...
    • The SKA particle array prototype: The first particle detector at the Murchison Radio-astronomy Observatory
      Bray, J.D.; Williamson, A.; Schelfhout, J.; James, Clancy ; Spencer, R.E.; Chen, H.; Cropper, B.D.; Emrich, David ; Gould, K.M.L.; Haungs, A.; Hodder, W.; Howland, T.; Huege, T.; Kenney, David ; McPhail, A.; Mitchell, S.; Niţu, I.C.; Roberts, P.; Tawn, R.; Tickner, Jonathan ; Tingay, Steven (2020)
      We report on the design, deployment, and first results from a scintillation detector deployed at the Murchison Radio-astronomy Observatory (MRO). The detector is a prototype for a larger array – the Square Kilometre Array ...
    • Rational design of ZnO-zeolite imidazole hybrid nanoparticles with reduced charge recombination for enhanced photocatalysis
      Fatima, Hira; Azhar, Muhammad Rizwan; Zhong, Yijun ; Arafat, Yasir; Khiadani, M.; Shao, Zongping (2022)
      Semiconducting zinc oxide nanoparticles (ZnO NPs) hold great potential as photocatalysts in wastewater treatment because of their favorable bandgap and cost-effectiveness. Unfortunately, ZnO NPs usually show rapid charge ...
    • Ultrasonic Characterization of Compacted Salty Kaolin–Sand Mixtures Under Nearly Zero Vertical Stress Using Experimental Study and Machine Learning
      Baghbani, Abolfazl; Shirani Faradonbeh, Roohollah ; Abuel-Naga, Hossam; Costa, Susanga; Almasoudi, Rayed (2023)
      Understanding the dynamic behavior of soil is crucial for developing effective mitigation strategies for natural hazards such as earthquakes, landslides, and soil liquefaction, which can cause significant damage and loss ...
    • Predicting the response of locally resonant concrete structure under blast load
      Jin, H.; Hao, Hong ; Hao, Yifei ; Chen, Wensu (2020)
      Ternary locally resonant metamaterial (LRM) is a manmade material consisting of rigorously designed heavy inclusions with coated soft layer. Such design enables the LRM to possess good wave-filtering characteristics that ...
    • Spall Behaviors of Metaconcrete: 3D Meso-Scale Modelling
      Jin, H.; Hao, Hong ; Chen, Wensu ; Xu, Cheng (2021)
      Spalling is a typical tensile fracture phenomenon due to insufficient tensile strength of concrete. Concrete structure might experience severe spall damage at the rear surface of the structure owing to reflected tensile ...
