Fisher Forecasting for the DESC with

Paul Rogozenski, Sankarshana Srinivasan, Javier Sánchez +18

The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) has begun its ten-year survey of the entire visible southern hemisphere. To ensure robust cosmological measurem…

KiDS-Legacy: The consistency test of the large-scale structure with Bernardeau-Nishimichi-Taruya transform

Shiming Gu, Ziang Yan, Ludovic van Waerbeke +10

We perform the first -cut cosmic shear analysis of the KiDS-Legacy survey. This method uses the Bernardeau-Nishimichi-Taruya (BNT) transform to construct weak-lensing kernels th…

Balancing bias, baryons, and scale cuts in LSST 3x2pt analysis

Ottavia Truttero, Maria Tsedrik, Joe Zuntz +4

Stage IV surveys such as LSST will probe deeply into the nonlinear regime, where systematic effects from galaxy bias and baryonic feedback become dominant and poorly constrained nu…

KiDS-Legacy: Constraining dark energy, neutrino mass, and curvature

Robert Reischke, Benjamin Stölzner, Benjamin Joachimi +25

We constrained minimally extended cosmological models with the cosmic shear analysis of the final data release from the Kilo-Degree Survey (KiDS-Legacy) in combination with externa…

Probing Physics Beyond the Standard Model through Combined Analyses of Next-Generation Type Ia Supernova, CMB, and BAO Surveys

Srinivasan Raghunathan, Ayan Mitra, Nikolina Šarčević +11

Observations of Type Ia supernovae (\sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe th…

Smokescreen: A Python package for data vector blinding and encryption in cosmological analyses

Arthur Loureiro, Jessica Muir, Jonathan Blazek +10

Smokescreen is an open-source Python library for data-vector concealment (blinding) in cosmological analyses. Data-vector blinding works by applying cosmology-dependent shifts to t…
