A prediction for anisotropies in the nearby Hubble flow
Asta Heinesen, Hayley J. Macpherson
We assess the dominant low-redshift anisotropic signatures in the distance-redshift relation and redshift drift signals. We adopt general-relativistic irrotational dust models allo…
Covariant transverse-traceless projection for secondary gravitational waves
Atsuhisa Ota, Hayley J. Macpherson, William R. Coulton
Second-order tensor modes induced by nonlinear gravity are a key component of the cosmological background of gravitational waves. A detection of this background would allow us to p…
Luminosity distance and anisotropic sky-sampling at low redshifts: a numerical relativity study
Hayley J. Macpherson, Asta Heinesen
Most cosmological data analysis today relies on the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric, providing the basis of the current standard cosmological model. Within this f…
