Observational future of cosmological scalar-tensor theories by Alonso, D, Bellini, E, Ferreira, P, Zumalacárregui, M

Relativistic imprints on dispersion measure space distortions by Saga, S, Alonso, D

“…As a distance indicator, dispersion measure is systematically affected by inhomogeneities in the electron density along the line of sight and special and general relativistic effects, similar to the case of redshift surveys. We present analytic expressions for the correlation function of fast radio bursts (FRBs) and for the galaxy-FRB cross-correlation function, in the presence of these dispersion measure-space distortions. …”

Science-driven 3D data compression by Alonso, D

A filament of dark matter between two clusters of galaxies. by Dietrich, J, Werner, N, Clowe, D, Finoguenov, A, Kitching, T, Miller, L, Simionescu, A

“…The thread-like structure of this 'cosmic web' has been traced by galaxy redshift surveys for decades. More recently, the warm–hot intergalactic medium (a sparse plasma with temperatures of 10(5) kelvin to 10(7) kelvin) residing in low-redshift filaments has been observed in emission and absorption. …”

Lopsided Satellite Distributions around Isolated Host Galaxies in a ΛCDM Universe by Adam Samuels, Tereasa G. Brainerd

The impact of relativistic effects on cosmological parameter estimation by Lorenz, C, Alonso, D, Ferreira, P

“…We study this claim in detail by focusing on a subset of wide-area future surveys: Stage-4 cosmic microwave background experiments and photometric redshift surveys. In particular, we look at the magnification lensing contribution to galaxy clustering and general relativistic corrections to all observables. …”

Cosmology with the Square Kilometre Array by Blake, C, Abdalla, F, Bridle, S, Rawlings, S

“…We conclude that data from the SKA will yield transformational science as the direct result of four key features: (i) the immense cosmic volumes probed, exceeding future optical redshift surveys by more than an order of magnitude; (ii) well-controlled systematic effects such as the narrow `k-space window function' for Experiment I and the accurately-known `point-spread function' for Experiment II; (iii) the ability to measure with high precision large-scale modes in the clustering power spectra, for which nuisance effects such as non-linear structure growth, peculiar velocities and `galaxy bias' are minimised; and (iv) different degeneracies between key parameters to those which are inherent in the CMB.…”

Reconstructing cosmic growth with kinetic Sunyaev-Zel’dovich observations in the era of stage IV experiments by Alonso, D, Louis, T, Bull, P, Ferreira, P

“…We describe a method for constraining the growth rate of structure to sub-1% precision out to z≈1, using a combination of galaxy cluster peculiar velocities measured using the kinetic Sunyaev-Zel'dovich (kSZ) effect, and the velocity field reconstructed from galaxy redshift surveys. We consider only thermal SZ-selected cluster samples, which will consist of O(104-105) sources for Stage 3 and 4 CMB experiments respectively. …”

Ultra-large-scale cosmology in next-generation experiments with single tracers by Alonso, D, Bull, P, Ferreira, P, Maartens, R, Santos, M
