DESI Strong Lens Foundry I: HST Observations and Modeling with GIGA-Lens
X. Huang, S. Baltasar, N. Ratier-Werbin +56
We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lens Foundry. We discovered new strong gravitational lens candidates in the DESI Legacy Imaging Survey…
CURLING - I. The Influence of Point-like Image Approximation on the Outcomes of Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Nan Li +11
Cluster-scale strong lensing is a powerful tool for exploring the properties of dark matter and constraining cosmological models. However, due to the complex parameter space, pixel…
Towards cosmology with Void Lensing: how to find voids sensitive to weak-lensing and numerically interpret them
Renan Boschetti, Pauline Vielzeuf, Marie-Claude Cousinou +2
In this work, we present a study of the void lensing signal or the excess surface mass density (ESMD) around cosmic voids. First, we propose a new void-finder algorithm that is des…
AMICO galaxy clusters in KiDS-DR3: Measurement of the halo bias and power spectrum normalization from a stacked weak lensing analysis
Lorenzo Ingoglia, Giovanni Covone, Mauro Sereno +19
Galaxy clusters are biased tracers of the underlying matter density field. At very large radii beyond about 10 Mpc/\textit{h}, the shear profile shows evidence of a second-halo ter…
Impact of baryons in cosmic shear analyses with tomographic aperture mass statistics
Nicolas Martinet, Tiago Castro, Joachim Harnois-Déraps +3
NonGaussian cosmic shear statistics based on weak-lensing aperture mass () maps can outperform the classical shear two-point correlation function (-2PCF) in terms of…
Does Concentration Drive the Scatter in the Stellar-to-Halo Mass Relation of Galaxy Clusters?
Ying Zu, Huanyuan Shan, Jun Zhang +10
Concentration is one of the key dark matter halo properties that could drive the scatter in the stellar-to-halo mass relation of massive clusters. We derive robust photometric stel…
