Euclid preparation. Testing analytic models of galaxy intrinsic alignments in the Euclid Flagship simulation

Key Points

• Galaxy intrinsic alignments are assessed using various analytic models, contributing to understanding cosmic structures.
• The study examines simulation data, showing how different models influence the analysis of galaxy alignments.
• Assessment involves multiple analytic models applied to the Euclid Flagship simulation data for galaxy analysis.
• Findings suggest that precise modeling of intrinsic alignments is critical for future cosmic observations.
