Description
Operational and near-future astronomical surveys of the galaxy distribution
will soon put to the test our best ideas as to the nature of the current cosmic
acceleration. I will briefly review the status of some of the most interesting
proposals and then focus on LSS probes. The perturbative treatment of LSS, especially
in its effective theory realization, can well describe the quasi-linear regime of
structure formation. This regime is a precious repository of key information on
both early and late-time Universe dynamics. I will elaborate on recent progress
towards including a dark energy or a modified gravity component in this
framework. Quasi-linear scales have special relevance for testing any beyond
LCDM model as these can perturbatively access screening dynamics.
