Quantifying the Impact of LSST <i>u</i> -band Survey Strategy on Photometric Redshift Estimation and the Detection of Lyman-break Galaxies Open
The Vera C. Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST), promising to discover billions of galaxies out to redshift 7, using six photometric bands ( ugrizy ) spanning the near-ultraviolet to the near-infrared.…

Towards including super-sample covariance in the unbinned likelihood for cluster abundance cosmology Open
The measurement of the abundance of galaxy clusters in the Universe is a sensitive probe of cosmology, which depends on both the expansion history of the Universe and the growth of structure. Density fluctuations across the finite survey v…

Multipole analysis of cluster weak lensing shear in The Three Hundred project Open
Weak gravitational lensing is an important tool to estimate the masses of galaxy clusters, as it allows us to directly access their projected surface mass density along the line-of-sight (LOS) in a manner largely independent of their dynam…

Galaxy cluster cosmology in the LSST era Open
Les amas de galaxies sont des traceurs de la croissance des structures et de l'expansion de l’Univers. La mesure de leur abondance permet à la fois d’étudier la nature de l'énergie sombre et celle de la matière sombre, et figure aujourd’hu…

Testing the accuracy of likelihoods for cluster abundance cosmology Open
The abundance of galaxy clusters is a sensitive probe to the amplitude of matter density fluctuations, the total amount of matter in the Universe as well as its expansion history. Inferring correct values and accurate uncertainties of cosm…

Statistical properties of the gravitational force through ordering statistics Open
We study the statistical distribution of Newtonian gravitational forces acting on a test particle embedded in an infinite, homogeneous, and uncorrelated random gas of particles. In the limit where both the number of neighboring particles a…

Validating Synthetic Galaxy Catalogs for Dark Energy Science in the LSST Era Open
Large simulation efforts are required to provide synthetic galaxy catalogs for ongoing and upcoming cosmology surveys. These extragalactic catalogs are being used for many diverse purposes covering a wide range of scientific topics. In ord…

CLMM: a LSST-DESC cluster weak lensing mass modeling library for cosmology Open
We present the v1.0 release of CLMM, an open source python library for the estimation of the weak lensing masses of clusters of galaxies. CLMM is designed as a stand-alone toolkit of building blocks to enable end-to-end analysis pipeline v…

Statistical properties of the gravitational force in a random homogeneous medium Open
We discuss the statistical distribution of the gravitational (Newtonian) force exerted on a test particle in a infinite random and homogeneous gas of non-correlated particles (stars, galaxies, ...) where the first configuration of particle…
