Using 1000 mock realizations matched to the ASPIRE survey, the authors find cosmic variance increases clustering errors by ~3x over Poisson estimates and widens minimum halo mass uncertainties by 1.5-3x for z~6 quasars and emission-line galaxies.
Inverting Fisher biases enables quick checks on whether specific systematics explain cosmological tensions.
Little red dots shift from underdense, low-halo-mass environments at z>4 to ordinary galaxy environments by z~3.5, explaining their declining abundance at z<3.
GRAMSCI v2 replaces binary-search N-point enumeration with O(m) merge-walks, adds parity-decomposed and connected 4pCF, and ports the query engine to OpenACC GPUs with out-of-core tiling.
Empirical halo-to-[O III] emitter modeling with realistic JWST survey mocks produces cross-correlations consistent with z~6 data within large scatter, but with a ~10 cMpc offset in the 1D peak.
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.

The impact of source and survey modelling on the connection between [O III] emitters and Ly $\alpha$ forest transmission at z ~ 6
Empirical halo-to-[O III] emitter modeling with realistic JWST survey mocks produces cross-correlations consistent with z~6 data within large scatter, but with a ~10 cMpc offset in the 1D peak.
