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
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?
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
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


Cosmology from large-scale structure: Constraining $\Lambda$CDM with BOSS.
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cosmologicalExpand
Cosmological Model Insensitivity of Local H 0 from the Cepheid Distance Ladder
The observed tension ($\sim 9\%$ difference) between the local distance ladder measurement of the Hubble constant, $H_0$, and its value inferred from the cosmic microwave background (CMB) could hintExpand
Planck 2018 results. VIII. Gravitational lensing.
We present measurements of the cosmic microwave background (CMB) lensing potential using the final $\textit{Planck}$ 2018 temperature and polarization data. We increase the significance of theExpand
Testing modified gravity with cosmic shear
We use the cosmic shear data from the Canada-France-Hawaii Telescope Lensing Survey to place constraints on $f(R)$ and {\it Generalized Dilaton} models of modified gravity. This is highlyExpand
KiDS+VIKING-450 and DES-Y1 combined: Cosmology with cosmic shear
We present a combined tomographic weak gravitational lensing analysis of the Kilo Degree Survey (KV450) and the Dark Energy Survey (DES-Y1). We homogenize the analysis of these two public cosmicExpand
H0LiCOW XIII. A 2.4% measurement of $H_{0}$ from lensed quasars: $5.3\sigma$ tension between early and late-Universe probes
We present a measurement of the Hubble constant ($H_{0}$) and other cosmological parameters from a joint analysis of six gravitationally lensed quasars with measured time delays. All lenses exceptExpand
KiDS+GAMA: Constraints on Horndeski gravity from combined large-scale structure probes
We present constraints on Horndeski gravity from a combined analysis of cosmic shear, galaxy–galaxy lensing and galaxy clustering from |$450\, \mathrm{deg}^2$| of the Kilo-Degree Survey and theExpand
Using the Tilted flat-ΛCDM and the Untilted Non-flat ΛCDM Inflation Models to Measure Cosmological Parameters from a Compilation of Observational Data

Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
