Constraining modified gravity with weak lensing peaks
Christopher T. Davies, Joachim Harnois-Déraps, Baojiu Li +3
It is well established that maximizing the information extracted from upcoming and ongoing stage-IV weak-lensing surveys requires higher-order summary statistics that complement th…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Unleashing cosmic shear information with the tomographic weak lensing PDF
Lina Castiblanco, Cora Uhlemann, Joachim Harnois-Déraps +1
In this work, we demonstrate the constraining power of the tomographic weak lensing convergence PDF for StageIV-like source galaxy redshift bins and shape noise. We focus on scales…
Cosmology from weak lensing peaks and minima with Subaru Hyper Suprime-Cam survey first-year data
Gabriela A. Marques, Jia Liu, Masato Shirasaki +7
We present cosmological constraints derived from peak counts, minimum counts, and the angular power spectrum of the Subaru Hyper Suprime-Cam first-year (HSC Y1) weak lensing shear…
Forecasting the power of Higher Order Weak Lensing Statistics with automatically differentiable simulations
Denise Lanzieri, François Lanusse, Chirag Modi +4
We present the Differentiable Lensing Lightcone (DLL), a fully differentiable physical model designed for being used as a forward model in Bayesian inference algorithms requiring a…
Euclid Preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
Euclid Collaboration, V. Ajani, M. Baldi +211
Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms of statistical precis…
MGLenS: Modified gravity weak lensing simulations for emulation-based cosmological inference
Joachim Harnois-Déraps, Cesar Hernandez-Aguayo, Carolina Cuesta-Lazaro +4
We present MGLenS, a large series of modified gravity lensing simulations tailored for cosmic shear data analyses and forecasts in which cosmological and modified gravity parameter…
Starlet higher order statistics for galaxy clustering and weak lensing
Virginia Ajani, Joachim Harnois-Déraps, Valeria Pettorino +1
We present a first application to photometric galaxy clustering and weak lensing of wavelet based multi-scale higher order summary statistics: starlet peak counts and starlet $\ell…
Enhancing cosmic shear with the multi-scale lensing PDF
Benjamin Giblin, Yan-Chuan Cai, Joachim Harnois-Déraps
We quantify the cosmological constraining power of the `lensing PDF' - the one-point probability density of weak lensing convergence maps - by modelling this statistic numerically…
KiDS-1000 Cosmology: Constraints from density split statistics
Pierre A. Burger, Oliver Friedrich, Joachim Harnois-Déraps +13
Context. Weak lensing and clustering statistics beyond two-point functions can capture non-Gaussian information about the matter density field, thereby improving the constraints on…
