New non-spherical halo solving procedure applied to AGORA simulations shows merger-responsive morphology measures and redshift trends in spin, axis ratio, and overdensity.
VERSUS is a void-finding algorithm that identifies spherical underdensities matching excursion-set predictions for the void size function, validated on synthetic particles and AbacusSummit mocks with realistic galaxy populations.
Full-GR simulations find that inhomogeneous curvature produces only sub-dominant systematic offsets in growth-rate measurements from magnitude fluctuations at z ≲ 0.2 relative to current statistical errors.
Validates redshift-space power spectrum and bispectrum analysis on Abacus-PNG mocks to recover unbiased f_NL constraints for Euclid spectroscopic sample.
A new halo occupation model called HOMe reproduces the anisotropic clustering of ELGs and LRGs down to 200 h^{-1} kpc scales by sampling satellites from dark matter particle positions and fitting parameters to two-point statistics.
A catalogue of 37 voids (radii 13-38 h^{-1} Mpc) and 42 knots (volumes 10^4 to 3.3x10^5 h^{-3} Mpc^3) is presented using V-web on CF4++ZOA peculiar velocities within z=0.1.
