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.
