The Hubble constant tension with next-generation galaxy surveys
Carlos A. P. Bengaly, Chris Clarkson, Roy Maartens
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 m…
The observed galaxy bispectrum from single-field inflation in the squeezed limit
Kazuya Koyama, Obinna Umeh, Roy Maartens +1
Using the consistency relation in Fourier space, we derive the observed galaxy bispectrum from single-field inflation in the squeezed limit, in which one of the three modes has a w…
Probing the Cosmological Principle in the counts of radio galaxies at different frequencies
C. A. P. Bengaly, R. Maartens, M. G. Santos
According to the Cosmological Principle, the matter distribution on very large scales should have a kinematic dipole that is aligned with that of the CMB. We determine the dipole a…
Probing the imprint of interacting dark energy on very large scales
Didam Duniya, Daniele Bertacca, Roy Maartens
The observed galaxy power spectrum acquires relativistic corrections from lightcone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infr…
Cosmology on the Largest Scales with the SKA
S. Camera, A. Raccanelli, P. Bull +10
The study of the Universe on ultra-large scales is one of the major science cases for the Square Kilometre Array (SKA). The SKA will be able to probe a vast volume of the cosmos, t…
Cosmological performance of SKA HI galaxy surveys
S. Yahya, P. Bull, M. G. Santos +4
The Square Kilometre Array (SKA) will conduct the biggest spectroscopic galaxy survey ever, by detecting the 21cm emission line of neutral hydrogen (HI) from around a billion galax…
