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 ...
Detecting the relativistic galaxy bispectrum
(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 ...
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, ...
