Studies on the dark sector interaction from joint analysis of cosmological probes
Jianfeng Meng, Xiaofeng Yang, Yunliang Ren +4
We test whether constraints on the nonlinear interaction IDE are stable under different treatments of the Type Ia supernovae absolute calibration. \textit{Fermi} GRBs measuremen…

Interacting dark energy constraints from Fermi GRBs and Pantheon+ SNe Ia with full GRB covariance
Jianfeng Meng, Xiaofeng Yang, Yunliang Ren +4
The standard CDM model faces long-standing theoretical and observational problems, such as the Hubble tension, which motivate extensions beyond CDM, including interacting dar…
