Alleviating the tension through the interacting dark energy model from quantum gravitational field theory in light of DESI DR2
Yi-Min Zhang, Tian-Nuo Li, Guo-Hong Du +4
Recent DESI DR2 data has shown a significant preference for dynamical dark energy, yet this has further exacerbated the tension. In this work, we explore the potential of int…

Extracting the Epoch of Reionization Signal with 3D U-Net Neural Networks Using Data-driven Systematic Effect Model
Li-Yang Gao, Léon V. E. Koopmans, Florent G. Mertens +11
Neutral hydrogen (HI) serves as a crucial probe for the Cosmic Dawn and the Epoch of Reionization (EoR). Actual observations of the 21-cm signal often encounter challenges such as…
