We present constraints on extensions to the flat $\Lambda$CDM cosmological model by varying the spatial curvature $\Omega_K$, the sum of the neutrino masses $\sum m_\nu$, the dark energy equation of state parameter $w$, and the Hu-Sawicki $f(R)$ gravity $f_{R0}$ parameter. With the combined $3\times2$pt measurements of cosmic shear from the Kilo-Degree Survey (KiDS-1000), galaxy clustering from the Baryon Oscillation Spectroscopic Survey (BOSS), and galaxy-galaxy lensing from the overlap… Expand

Interacting dark energy from redshift-space galaxy clustering
• Physics
• 2021
Interacting dark energy models have been proposed as attractive alternatives to ΛCDM. Forthcoming Stage-IV galaxy clustering surveys will constrain these models, but they require accurate modellingExpand
Do gamma-ray burst measurements provide a useful test of cosmological models?
• Physics
• 2021
Context. We study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements — that probe a largely unexplored part of cosmological redshift (z) space — can be usedExpand
Hamilton’s Object – a clumpy galaxy straddling the gravitational caustic of a galaxy cluster: constraints on dark matter clumping
• Physics
• 2021
We report the discovery of a ‘folded’ gravitationally lensed image, ’Hamilton’s Object’, found in a HST image of the field near the AGN SDSS J223010.47-081017.8 (which has redshift 0.62). The lensedExpand
KiDS-1000 catalogue: Redshift distributions and their calibration
We present redshift distribution estimates of galaxies selected from the fourth data release of the Kilo-Degree Survey over an area of $\sim1000$ deg$^2$ (KiDS-1000). These redshift distributionsExpand
