DESI: Overview and the Latest Cosmological Results from Clustering Measurements

The Dark Energy Spectroscopic Instrument (DESI) is mapping the three-dimensional distribution of galaxies and quasars to trace the Universe's expansion history and the growth of structure, enabling precision tests of dark energy and gravity. Over its eight years survey, DESI is expected to obtain approximately 63 million spectroscopically-confirmed spectra, delivering high-precision constraints on key cosmological parameters across a broad redshift range and multiple tracers. In this talk, I will give a brief overview of DESI and summarize the main cosmological results obtained so far. I will also provide status updates on Data Release 2 (DR2), with particular focus on the developments on the full-shape analysis side, including methodological refinements and analysis choices informed by the expanded dataset. I will conclude with an outlook on next steps, including forthcoming analyses, and the path toward increasingly stringent tests of the standard cosmological model.
