Description
The nature of Dark Energy remains one of the most profound mysteries in modern cosmology, acting as the primary driver behind the late-time accelerated expansion of the universe. This talk explores the current landscape of dark energy research in light of the latest Baryon Acoustic Oscillation (BAO) observations from premier surveys such as the Dark Energy Spectroscopic Instrument (DESI). We will examine how these "standard rulers" provide high-precision measurements of the Hubble parameter $H(z)$ and the angular diameter distance $d_A(z)$, allowing us to map the expansion history of the cosmos with unprecedented accuracy.
