Cosmology with Phase 1 of the Square Kilometre Array Red Book 2018: Technical specifications and performance forecasts
Bacon, DJ; Battye, RA; Bull, P; Camera, S; Ferreira, PG; Harrison, I; Parkinson, D; Pourtsidou, A; Santos, MG; Wolz, L (Astronomical Society of Australia, 2020)We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight three main surveys: a medium-deep ... -
Detecting the relativistic galaxy bispectrum
Maartens, R; Jolicoeur, S; Umeh, O; Weerd, EMD; Clarkson, C; Camera, S (IOP Publishing, 2020-03)The Fourier galaxy bispectrum is complex, with the imaginary part arising from leading-order relativistic corrections, due to Doppler, gravitational redshift and related line-of-sight effects in redshift space. The detection ... -

Imprints of local lightcone projection effects on the galaxy bispectrum IV: Second-order vector and tensor contributions
CLARKSON, CA; Jolicoeur, S; Allahyari, A; Larena, J; Umeh, O; Maartens, R (IOP Publishing, 2019)The galaxy bispectrum on scales around and above the equality scale receives contributions from relativistic effects. Some of these arise from lightcone deformation effects, which come from local and line-of-sight integrated ... -

Probing beyond-Horndeski gravity on ultra-large scales
Duniya, DGA; Moloi, T; Clarkson, C; Larena, J; Maartens, R; Mongwane, B; Weltman, A (IOP Publishing, 2020-01-14)The beyond-Horndeski gravity has recently been reformulated in the dark energy paradigm—which has been dubbed, Unified Dark Energy (UDE). The evolution equations for the given UDE appear to correspond to a non-conservative ... -

Ultra large-scale cosmology in next-generation experiments with single tracers
Alonso, D; Bull, P; Ferreira, PG; Maartens, R; Santos, M (IOP Publishing, 2015)Future surveys of large-scale structure will be able to measure perturbations on the scale of the cosmological horizon, and so could potentially probe a number of novel relativistic effects that are negligibly small on ... -
