    • Cleaning foregrounds from single-dish 21 cm intensity maps with Kernel principal component analysis 

      Irfan, Melis O; Bull, Phillip (Oxford University Press, 2021)
      he high dynamic range between contaminating foreground emission and the fluctuating 21 cm brightness temperature field is one of the most problematic characteristics of 21 cm intensity mapping data. While these components ...

      Jarvis, Matt J; Pan, Hengxing; Ponomareva, Anastasia A; Maddox, Natasha (Oxford University Press, 2023)
      We present the first measurement of the H I mass function (HIMF) using data from MeerKAT, based on 276 direct detections from the MeerKAT International GigaHertz Tiered Extragalactic Exploration (MIGHTEE) Survey Early ...

    • WALLABY – an SKA Pathfinder H I survey 

      Cluver, M.E.; Koribalski, Bärbel S.; Staveley-Smith, L. (Springer Nature, 2020)
      The Widefield ASKAP L-band Legacy All-sky Blind surveY (WALLABY) is a next-generation survey of neutral hydrogen (H I) in the Local Universe. It uses the widefield, high-resolution capability of the Australian Square ...
