Optimization of Weak Lensing Lightcone Simulations for Higher-Order Statistics in the LSST era
J. Mena-Fernández, C. Doux, J. Harnois-Déraps +9
We present a framework for generating lightcone simulations tailored to the analysis of Stage-IV cosmic shear data using Higher-Order Statistics (HOS). We revisit key design choice…
Non-linear infusion of intrinsic alignment and source clustering: impact on non-Gaussian cosmic shear statistics
J. Harnois-Déraps, N. Šarčević, L. Medina Varela +15
Intrinsic alignments (IA) of galaxies is one of the key secondary signals to cosmic shear measurements, and must be modeled to interpret weak lensing data and infer the correct cos…
Impact of survey spatial variability on galaxy redshift distributions and the cosmological -point statistics for the Rubin Legacy Survey of Space and Time (LSST)
Qianjun Hang, Benjamin Joachimi, Eric Charles +7
We investigate the impact of spatial survey non-uniformity on the galaxy redshift distributions for forthcoming data releases of the Rubin Observatory Legacy Survey of Space and Ti…
The picasso gas model: Painting intracluster gas on gravity-only simulations
F. Kéruzoré, L. E. Bleem, N. Frontiere +5
We introduce picasso, a model designed to predict thermodynamic properties of the intracluster medium based on the properties of halos in gravity-only simulations. The predictions…
Exploring the Core-galaxy Connection
Isabele Souza Vitório, Michael Buehlmann, Eve Kovacs +3
Halo core tracking is a novel concept designed to efficiently follow halo substructure in large simulations. We have recently developed this concept in gravity-only simulations to…
Optimization and Quality Assessment of Baryon Pasting for Intracluster Gas using the Borg Cube Simulation
F. Kéruzoré, L. E. Bleem, M. Buehlmann +5
Synthetic datasets generated from large-volume gravity-only simulations are an important tool in the calibration of cosmological analyses. Their creation often requires accurate in…
