Abstract
Current discrepancies between datasets analyzed in the standard model open the possibility for beyond-LCDM model physics, such as evolving dark energy. However, departures from the standard theory of gravity itself can be potentially misinterpreted as dark energy. Fortunately, the growth of galaxy clustering data provides a way to distinguish between the two. In this talk, we present the latest results on dark energy and tests of gravity from the full-shape analysis using the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI).
