Understanding the suppression of structure formation from dark matter$\unicode{x2013}$dark energy momentum coupling
Finlay Noble Chamings, Anastasios Avgoustidis, Edmund J. Copeland +2
Models in which scalar field dark energy interacts with dark matter via a pure momentum coupling have previously been found to potentially ease the structure formation tension betw…
Hybrid : general, unified, non-linear matter power spectrum in redshift space
Benjamin Bose, Hans A. Winther, Alkistis Pourtsidou +4
Constraints on gravity and cosmology will greatly benefit from performing joint clustering and weak lensing analyses on large-scale structure data sets. Utilising non-linear inform…
Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
Euclid preparation: VII. Forecast validation for Euclid cosmological probes
Euclid Collaboration, A. Blanchard, S. Camera +151
The Euclid space telescope will measure the shapes and redshifts of galaxies to reconstruct the expansion history of the Universe and the growth of cosmic structures. Estimation of…
Prospects for cosmic magnification measurements using HI intensity mapping
Amadeus Witzemann, Alkistis Pourtsidou, Mario G. Santos
We investigate the prospects of measuring the cosmic magnification effect by cross-correlating neutral hydrogen intensity mapping (HI IM) maps with background optical galaxies. We…
Assessing non-linear models for galaxy clustering II: model validation and forecasts for Stage IV surveys
Benjamin Bose, Alkistis Pourtsidou, Katarina Markovič +1
Accurate modelling of non-linear scales in galaxy clustering will be crucial for data analysis of Stage IV galaxy surveys. A selection of competing non-linear models must be made b…
