The accelerated expansion of our universe, driven by the enigmatic dark energy, remains one of the most profound mysteries in modern physics. Unraveling its nature requires a synergistic approach, combining cutting-edge observations and theoretical frameworks. The Dark Energy Spectroscopic Instrument (DESI) and the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) are at the forefront of this quest.
In this colloquium, I will discuss how DESI's unprecedented 3D mapping of millions of galaxies, coupled with Cosmic Microwave Background (CMB) and Supernovae observations, are providing unprecedented insights into the cosmic web and the distribution of matter on large scales. By analyzing the imprints left by dark energy and neutrino masses on these intricate structures, we aim to unravel the fundamental constituents of our universe. I will present the latest results from these collaborations and the theoretical developments employed to extract their profound cosmological signatures.
