When tension is just a fluctuation: How noisy data affect model comparison
B. Joachimi, F. Köhlinger, W. Handley +1
Summary statistics of the likelihood, such as the Bayesian evidence, offer a principled way of comparing models and assessing tension between, or within, the results of physical ex…
KiDS-1000 Cosmology: Cosmic shear constraints and comparison between two point statistics
Marika Asgari, Chieh-An Lin, Benjamin Joachimi +22
We present cosmological constraints from a cosmic shear analysis of the fourth data release of the Kilo-Degree Survey (KiDS-1000), doubling the survey area with nine-band optical a…
KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints
Catherine Heymans, Tilman Tröster, Marika Asgari +31
We present a joint cosmological analysis of weak gravitational lensing observations from the Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from…
KiDS-1000 Methodology: Modelling and inference for joint weak gravitational lensing and spectroscopic galaxy clustering analysis
B. Joachimi, C. -A. Lin, M. Asgari +24
We present the methodology for a joint cosmological analysis of weak gravitational lensing from the fourth data release of the ESO Kilo-Degree Survey (KiDS-1000) and galaxy cluster…
Quantifying Suspiciousness Within Correlated Data Sets
Pablo Lemos, Fabian Köhlinger, Will Handley +3
We propose a principled Bayesian method for quantifying tension between correlated datasets with wide uninformative parameter priors. This is achieved by extending the Suspiciousne…
KiDS+GAMA: Constraints on Horndeski gravity from combined large-scale structure probes
Alessio Spurio Mancini, Fabian Köhlinger, Benjamin Joachimi +7
We present constraints on Horndeski gravity from a combined analysis of cosmic shear, galaxy-galaxy lensing and galaxy clustering from of the Kilo-Degree Surv…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
A Bayesian quantification of consistency in correlated datasets
Fabian Köhlinger, Benjamin Joachimi, Marika Asgari +3
We present three tiers of Bayesian consistency tests for the general case of datasets. Building on duplicates of the model parameters assigned to each dataset, these t…
280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope
O. Vaduvescu, L. Hudin, T. Mocnik +80
One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
KiDS+GAMA: Cosmology constraints from a joint analysis of cosmic shear, galaxy-galaxy lensing and angular clustering
Edo van Uitert, Benjamin Joachimi, Shahab Joudaki +19
We present cosmological parameter constraints from a joint analysis of three cosmological probes: the tomographic cosmic shear signal in 450 deg of data from the Kilo Deg…
Precision calculations of the cosmic shear power spectrum projection
Martin Kilbinger, Catherine Heymans, Marika Asgari +9
We compute the spherical-sky weak-lensing power spectrum of the shear and convergence. We discuss various approximations, such as flat-sky, and first- and second- order Limber equa…
KiDS-450: Testing extensions to the standard cosmological model
Shahab Joudaki, Alexander Mead, Chris Blake +16
We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg of imaging data from the Kilo Degree Survey (KiDS). In these exte…
KiDS-450: Cosmological parameter constraints from tomographic weak gravitational lensing
H. Hildebrandt, M. Viola, C. Heymans +33
We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg of imaging data from the Kilo Degree Survey (KiDS). For a flat $…
A direct measurement of tomographic lensing power spectra from CFHTLenS
Fabian Köhlinger, Massimo Viola, Wessel Valkenburg +3
We measure the weak gravitational lensing shear power spectra and their cross-power in two photometric redshift bins from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLen…
Statistical uncertainties and systematic errors in weak lensing mass estimates of galaxy clusters
F. Köhlinger, H. Hoekstra, M. Eriksen
Upcoming and ongoing large area weak lensing surveys will also discover large samples of galaxy clusters. Accurate and precise masses of galaxy clusters are of major importance for…
Constraints on the Alignment of Galaxies in Galaxy Clusters from 14,000 Spectroscopic Members
Cristóbal Sifón, Henk Hoekstra, Marcello Cacciato +5
Torques acting on galaxies lead to physical alignments, but the resulting ellipticity correlations are difficult to predict. As they constitute a major contaminant for cosmic shear…
The Infrared Properties of Massive Stars in the Magellanic Clouds
A. Z. Bonanos, D. J. Lennon, D. L. Massa +9
We present results of our study of the infrared properties of massive stars in the Large and Small Magellanic Clouds, which are based on the Spitzer SAGE surveys of these galaxies.…
Spitzer SAGE-SMC Infrared Photometry of Massive Stars in the Small Magellanic Cloud
A. Z. Bonanos, D. J. Lennon, F. Köhlinger +18
We present a catalog of 5324 massive stars in the Small Magellanic Cloud (SMC), with accurate spectral types compiled from the literature, and a photometric catalog for a subset of…
