    • Calibrating photometric redshifts with intensity mapping observations 

      Alonso, David; Ferreira, Pedro G.; Jarvis, Matt; Moodley, Kavilan (American Physical Society, 2017)
      Imaging surveys of galaxies will have a high number density and angular resolution yet a poor redshift precision. Intensity maps of neutral hydrogen (HI) will have accurate redshift resolution yet will not resolve ...

    • Gaussian process regression for foreground removal in hi intensity mapping experiments 

      Soares, Paula S.; Watkinson, Catherine A.; Pourtsidou, Alkistis (Oxford University Press, 2022)
      We apply for the first time Gaussian Process Regression (GPR) as a foreground removal technique in the context of single-dish, low redshift H I intensity mapping, and present an open-source PYTHON toolkit for doing so. We ...

    • MIGHTEE: Are giant radio galaxies more common than we thought? 

      Prescott, M; Delhaize, J; Heywood, I (Oxford University Press, 2021)
      We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a ∼}1\, deg2 region inside the COSMOS field. ...
