Weak equivalence principle, swampland and tension with fast single radio bursts FRB 180924 and FRB 190523
Deng Wang, Zhaozhou Li, Jiajun Zhang
Two new fast single radio bursts FRB 180924 and FRB 190523 well localized to massive galaxies have opened a new window to probe and characterize how cosmic baryons are allocated be…

A Fully Self-Consistent Cosmological Simulation Pipeline for Interacting Dark Energy Models
Jiajun Zhang, Rui An, Shihong Liao +3
We devise a fully self-consistent simulation pipeline for the first time to study the interaction between dark matter and dark energy. We perform convergence tests and show that ou…

The first constraint from SDSS galaxy-galaxy weak lensing measurements on interacting dark energy models
Jiajun Zhang, Rui An, Wentao Luo +3
We combine constraints from linear and nonlinear scales, for the first time, to study the interaction between dark matter and dark energy. We devise a novel N-body simulation pipel…
