Multipoles of the relativistic galaxy bispectrum
(IOP Publishing Ltd, 2020)
Above the equality scale the galaxy bispectrum will be a key probe for measuring
primordial non-Gaussianity which can help differentiate between different inflationary models
and other theories of the early universe. On ...
The Hubble constant tension with next-generation galaxy surveys
(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, ...
Null tests of the concordance model in the era of Euclid and the SKA
(Elsevier, 2021)
We perform null tests of the concordance model, using H (z) measurements that mimic next-generation surveys such as Euclid and the SKA. To this end, we deploy a non-parametric method, so that we make minimal assumptions ...
Wide-angle effects in multi-tracer power spectra with Doppler corrections
(IOP Publishing, 2023)
. We examine the computation of wide-angle corrections to the galaxy power spectrum including redshift-space distortions and relativistic Doppler corrections, and also including multiple tracers with differing clustering, ...
