Exploring Cosmic Structures: Nonlinear Evolution and Anisotropies in the Cosmic Web

This research focuses on the complex interplay of nonlinear evolution, secondary anisotropies, and the cosmic web's structure, as shaped by phenomena such as weak lensing and the thermal and kinetic Sunyaev-Zel'dovich effects. We delve into primary anisotropies linked to tightly coupled photon-baryon fluid oscillations, examining their influences from gravitational redshifting to reionization. Our studies utilize observational data from projects like Planck, CBI, and others, addressing dark energy histories and probing CMB/LSS phenomenology for a deeper understanding of the universe's evolution.
