The fifth data release of the Kilo Degree Survey: Multi-epoch optical/NIR imaging covering wide and legacy-calibration fields
Angus H. Wright, Konrad Kuijken, Hendrik Hildebrandt +51
We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational lens…
Probing galaxy bias and intergalactic gas pressure with KiDS Galaxies-tSZ-CMB lensing cross-correlations
Ziang Yan, Ludovic van Waerbeke, Tilman Tröster +14
We constrain the redshift dependence of gas pressure bias (bias-weighted average electron pressure), which characterises the thermo…
KiDS+GAMA: The weak lensing calibrated stellar-to-halo mass relation of central and satellite galaxies
Andrej Dvornik, Henk Hoekstra, Konrad Kuijken +13
We simultaneously present constraints on the stellar-to-halo mass relation for central and satellite galaxies through a weak lensing analysis of spectroscopically classified galaxi…
On the road to percent accuracy IV: ReACT -- computing the non-linear power spectrum beyond CDM
Benjamin Bose, Matteo Cataneo, Tilman Tröster +3
To effectively exploit large-scale structure surveys, we depend on accurate and reliable predictions of non-linear cosmological structure formation. Tools for efficient and compreh…
The effects of varying depth in cosmic shear surveys
Sven Heydenreich, Peter Schneider, Hendrik Hildebrandt +7
We present a semi-analytic model for the shear two-point correlation function of a cosmic shear survey with non-uniform depth. Ground-based surveys are subject to depth variations…
KiDS+VIKING-450 and DES-Y1 combined: Mitigating baryon feedback uncertainty with COSEBIs
Marika Asgari, Tilman Tröster, Catherine Heymans +12
We present cosmological constraints from a joint cosmic shear analysis of the Kilo-Degree Survey (KV450) and the Dark Energy Survey (DES-Y1), conducted using Complete Orthogonal Se…
Cosmology from large-scale structure: Constraining CDM with BOSS
Tilman Tröster, Ariel. G. Sánchez, Marika Asgari +9
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cos…
Modelling baryonic feedback for survey cosmology
Nora Elisa Chisari, Alexander J. Mead, Shahab Joudaki +10
Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between to elucidate the nature of dark matter and dark e…
Painting with baryons: augmenting N-body simulations with gas using deep generative models
Tilman Tröster, Cameron Ferguson, Joachim Harnois-Déraps +1
Running hydrodynamical simulations to produce mock data of large-scale structure and baryonic probes, such as the thermal Sunyaev-Zeldovich (tSZ) effect, at cosmological scales is…
Probing hot gas around luminous red galaxies through the Sunyaev-Zel'dovich effect
Hideki Tanimura, Gary Hinshaw, Ian G. McCarthy +7
We construct the mean thermal Sunyaev-Zel'dovich (tSZ) Comptonization y profile around Luminous Red Galaxies (LRGs) in the redshift range 0.16 < z < 0.47 from the Sloan Digital Sky…
KiDS+VIKING-450: Cosmic shear tomography with optical+infrared data
H. Hildebrandt, F. Köhlinger, J. L. van den Busch +25
We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS) combined with the VISTA Kilo-Degree Infrared Galaxy Survey (VIKING). This is the first time that a f…
An Assessment of Contamination in the thermal-SZ Map Using Cross Correlations
Ziang Yan, Alireza Hojjati, Tilman Tröster +2
We search for the potential contamination in the Planck thermal Sunyaev-Zeldovich (tSZ) map by calculating the cross-correlation between the tSZ signal and weak lensing by large sc…
KiDS-450: Enhancing cosmic shear with clipping transformations
Benjamin Giblin, Catherine Heymans, Joachim Harnois-Déraps +12
We present the first "clipped" cosmic shear measurement using data from the Kilo-Degree Survey (KiDS-450). "Clipping" transformations suppress the signal from the highest density,…
Cosmological Simulations for Combined-Probe Analyses: Covariance and Neighbour-Exclusion Bias
J. Harnois-Deraps, A. Amon, A. Choi +12
We present a public suite of weak lensing mock data, extending the Scinet Light Cone Simulations (SLICS) to simulate cross-correlation analyses with different cosmological probes.…
