Forecasts that cross-correlating 3G GW dark sirens with CSST photometric galaxies yields 1.04% precision on H0 and 2.04% on Omega_m while also constraining GW clustering bias.
The mild open-universe signal in late-Universe data is an artifact of assuming the basic ΛCDM model rather than evidence for genuine spatial curvature.
DESI DR2 Lyman-alpha forest data combined with other probes yields up to 3.1 sigma preference for dynamical dark energy parameterizations over LambdaCDM, with w0 > -1 and wa < 0.
