FLAMINGO simulation analysis shows IA amplitude for LRGs depends on halo assembly history and exhibits redshift evolution beyond mass effects, yielding an empirical mass-redshift model.
Cross-correlation of SPT-3G CMB lensing and DES Y3 galaxy lensing measured at 14 sigma significance yields S8 = 0.833 +0.047 -0.061, consistent with Planck and DES Y3 shear-only results.
Forecasts indicate SKAO cosmic shear can constrain S8 to 5% alone and 3% combined with LSST or Euclid, with added benefits from polarization and kinematics for separating lensing signals.
UNIONS r-band data constrains S8 to 0.891^{+0.057}_{-0.084} via 2D harmonic-space cosmic shear, consistent with Planck at 0.79 sigma after modeling baryonic feedback and intrinsic alignments.
SKAO forecasts show that planned observations will improve SGWB anisotropy constraints but remain insufficient to detect the kinematic dipole even in joint PTA-astrometry analyses.
Machine learning techniques can mitigate limitations in traditional weak-lensing analyses and enhance extraction of cosmological information from galaxy imaging surveys.
