    • Detecting the relativistic galaxy bispectrum 

      Maartens, Roy; Jolicoeur, Sheean; Umeh, Obinna (IOP Publishing Ltd, 2020)
      The Fourier galaxy bispectrum is complex, with the imaginary part arising from leading-order relativistic corrections, due to Doppler, gravitational redshift and related lineof-sight effects in redshift space. The detection ...

    • Gravitational wave mergers as tracers of large scale structures 

      Karagiannis, D; Libanore, S; Artale, M.C (IOP Publishing Ltd, 2021)
      Clustering measurements of Gravitational Wave (GW) mergers in Luminosity Distance Space can be used in the future as a powerful tool for Cosmology. We consider tomographic measurements of the Angular Power Spectrum of ...

    • The Hubble constant tension with next-generation galaxy surveys 

      Bengaly, Carlos A.P.; Clarkson, Chris; Maartens, Roy (IOP Publishing Ltd, 2020)
      The rate at which the universe is expanding today is a fundamental parameter in cosmology which governs our understanding of structure formation and dark energy. However, current measurements of the Hubble constant, H0, ...

    • Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys 

      Ballardini, Mario; Murgia, Riccardo; Baldi, Marco (IOP Publishing Ltd, 2020)
      Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models of inflation and its alternatives. In order ...
