    • The detailed nature of active central cluster galaxies 

      Loubser, S.I.; Soechting, I.K. (Oxford Univ Press, 2013)
      We present detailed integral field unit observations of the central few kiloparsecs of the ionized nebulae surrounding four active central cluster galaxies (CCGs) in cooling flow clusters (Abell 0496, 0780, 1644 and ...

    • Investigating the star formation histories of the brightest cluster galaxies 

      Groenewald, D.N.; Loubser, S.I. (Oxford Univ Press, 2014)
      This article is devoted to the study of the central stellar populations of the brightest cluster galaxies (BCGs). High signal-to-noise ratio, long-slit spectra for a sample of 39 galaxies were fitted against two stellar ...

    • Stellar populations in the centres of brightest cluster galaxies 

      Loubser, S.I.; Sánchez-Blázquez, P.; Sansom, A.E.; Soechting, I.K. (Oxford Univ Press, 2009)
      This paper is part of a series devoted to the study of the stellar populations in brightest cluster galaxies (BCGs), aimed at setting constraints on the formation and evolution of these objects. We have obtained high ...

    • The void galaxy survey: photometry, structure and identity of void galaxies 

      Beygu, B.; Peletier, R.F.; Van der Hulst, J.M.; Jarrett, T.H.; Kreckel, K. (Oxford Univ Press, 2017)
      We analyse photometry from deep B-band images of 59 void galaxies in the Void Galaxy Survey (VGS), together with their near-infrared 3.6 μm and 4.5 μm Spitzer photometry. The VGS galaxies constitute a sample of void galaxies ...

    • The void galaxy survey: star formation properties 

      Beygu, B.; Kreckel, K.; Van der Hulst, J.M.; Jarrett, T.H.; Peletier, R. (Oxford Univ Press, 2016)
      We study the star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Current star formation rates are derived from H α and recent star formation rates from near-UV imaging. In addition, ...
