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…
Point Correlation Functions in Galaxy Surveys: Impact of Baryonic Feedback
Avijit Bera, Joachim Harnois-Déraps, Juan Mena-Fernández +5
We investigate the impact of baryonic feedback on two-point and three-point correlation functions (2PCFs and 3PCFs hereafter, respectively) involving galaxy density fields (g) and…
DESI-DR1 -pt analysis: consistent cosmology across weak lensing surveys
A. Porredon, C. Blake, J. U. Lange +70
We present a joint cosmological analysis of projected galaxy clustering observations from the Dark Energy Spectroscopic Instrument Data Release 1 (DESI-DR1), and overlapping weak g…
Stability of Thin Shell and Wormhole Configurations: Schwarzschild, Schwarzschild -- (Anti-) de Sitter, and FLRW Spacetimes
Travis Seth Rippentrop, Avijit Bera, Mustapha Ishak
The stability of thin shell wormholes and black holes to linearized spherically symmetric perturbations about a static equilibrium is analyzed. Thin shell formalism is explored and…
A direct detection method of galaxy intrinsic ellipticity-gravitational shear correlation in non-linear regimes using self-calibration
Avijit Bera, Leonel Medina Varela, Vinu Sooriyaarachchi +3
Intrinsic alignment (IA) of galaxies is a challenging source of contamination in the Cosmic shear (GG) signals. The galaxy intrinsic ellipticity-gravitational shear (IG) correlatio…
OpenUniverse2024: A shared, simulated view of the sky for the next generation of cosmological surveys
OpenUniverse, The LSST Dark Energy Science Collaboration, The Roman HLIS Project Infrastructure Team +58
The OpenUniverse2024 simulation suite is a cross-collaboration effort to produce matched simulated imaging for multiple surveys as they would observe a common simulated sky. Both t…
