abstract
We review one of the most fruitful areas in cosmology today that bridge theory and data - the temporal growth of large-scale structure. We go over the growth's physical foundations, and derive its behavior in simple cosmological models. While doing so, we explain how measurements of growth can be used to understand theory. We then review how some of the most mature cosmological probes - galaxy clustering, gravitational lensing, the abundance of clusters of galaxies, cosmic velocities, and cosmic microwave background - can be used to probe the growth of structure. We report the current constraints on growth, which are summarized as measurements of the parameter combination $f\sigma_8$ as a function of redshift, or else as the mass fluctuation amplitude parameter $S_8$. We finally illustrate several statistical approaches, ranging from the "growth index" parameterization to more general comparisons of growth and geometry, that can sharply test the standard cosmological model and indicate the presence of modifications to general relativity.

Revisiting Metastable Dark Energy in Light of DESI DR2 BAO and DESI DR1 Full-Shape Measurements
Metastable dark energy, where the vacuum energy decays at a constant rate, fits the data but is not required: some combinations show 2-3 sigma hints of decay, none decisively beats the cosmological constant.

The simple way to measure evolving dark energy without prior-volume effects
Absorbing the AP and growth amplitudes into EFTofLSS nuisance parameters removes prior-volume shifts and yields Stage III LSS-only evolving dark energy constraints aligned with DESI.

Testing Quasi-Linear Coasting Cosmologies with Late-Time Large-Scale Structure Growth
A closed-form growth factor for linearly expanding (coasting) cosmologies is derived and fit to fσ8 data, showing all tested models are consistent but Lambda-CDM is statistically preferred.

Cosmology with HI Intensity Mapping
SKAO HI intensity mapping forecasts yield competitive LambdaCDM constraints (e.g. H0 to ~0.3 km/s/Mpc optimistic) via power spectrum, BAO, bispectrum and stacking, complementary to CMB and optical surveys.
