Oral talk

Understanding the origin of cosmic acceleration and the persistent H_0 and S_8 tensions remains a major challenge in cosmology. In this talk, I explore alternatives to the standard LambdaCDM model based on both modified gravity and dynamical dark energy. Within the teleparallel framework, I discuss f(Q) and f(T) theories, showing how non-metricity and torsion can lead to novel cosmological...
