    • 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 ...

    • Werner Eissner (1930–2022): a pioneer in computational atomic physics 

      Lynas-Gray, Anthony E.; Bhatia, Anand K.; Mendoza, Claudio; Nahar, Sultana (Atoms, 2023)
      Werner Eissner (Figure 1), a pioneer in computational atomic physics, was born on 16 October 1930 in the city of Görlitz, Germany, to Bernhard and Frieda (née Eckert) Eissner. He lost both parents early in life, his father ...

    • Wide-angle effects in multi-tracer power spectra with Doppler corrections 

      Paul, Pritha; Clarkson, Chris; Maartens, Roy (IOP Publishing, 2023)
      . We examine the computation of wide-angle corrections to the galaxy power spectrum including redshift-space distortions and relativistic Doppler corrections, and also including multiple tracers with differing clustering, ...

    • A wide-area GMRT 610-MHz survey of ELAIS N1 field 

      Taylor, A. R.; Ishwara-Chandra, C. H.; Green, D. A. (Oxford University Press, 2020)
      In this paper, we present a wide-area 610-MHz survey of the ELAIS N1 field with the GMRT, covering an area of 12.8 deg2 at a resolution of 6 arcsec and with an rms noise of ∼40 μJy beam−1. This is equivalent to ∼20 μJy ...

    • The WISE Extended Source Catalog (WXSC). I. The 100 Largest Galaxies 

      Cluver, Michelle (University of the Western Cape, 2019)
      We present mid-infrared photometry and measured global properties of the 100 largest galaxies in the sky, including the well-studied Magellanic Clouds, Local Group galaxies M31 and M33, the Fornax and Virgo galaxy cluster ...

    • X-ray emission from hot gas in galaxy groups and clusters in SIMBA 

      Davé, Romeel; Robson, Dylan (Oxford University Press, 2020-08-31)
      We examine X-ray scaling relations for massive haloes (M500 > 1012.3 M) in the SIMBA galaxy formation simulation. The X-ray luminosity, LX versus M500 has power-law slopes ≈5 3 and ≈8 3 above and below 1013.5 M, deviating ...

    • The XXL survey XLII. Detection and characterization of the galaxy population of distant galaxy clusters in the XXL-N/VIDEO field: A tale of variety 

      Jarvis, M.; Trudeau, A.; Garrel, C. (ESO, 2020)
      Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times. Aims. We aim to identify distant galaxy clusters as extended X-ray sources ...
