The impact of evolving dark energy on the Weyl potential measured from the Dark Energy Survey Year 3 data
Benedetta Rosatello, Gen Ye, Maria Berti +3
Measurements from the Dark Energy Survey (DES) Year 3 data have shown that the Weyl potential -- the sum of the spatial and temporal distortions of the geometry -- evolves more slo…
Late-time reconstruction of non-minimally coupled gravity with a smoothness prior
Gen Ye, Anton Chudaykin, Camille Bonvin +1
We present a non-parametric, model-independent reconstruction of the cosmological background and perturbation dynamics in non-minimally coupled theories of gravity. Within the Effe…
On the tension between DESI DR2 BAO and CMB
Gen Ye, Shi-Jie Lin
Recent DESI DR2 baryon acoustic oscillation (BAO) measurement shows inconsistency with the cosmic microwave background (CMB) observation in CDM. We used the Bayesian suspiciousn…
Null energy condition violation and beyond Horndeski physics in light of DESI DR2 data
Gen Ye, Yong Cai
Inflation and dark energy (DE), both featuring accelerated expansion, are crucial components of modern cosmology. As indicated by singularity theorems, null energy condition (NEC)…
Null energy condition violation during inflation and pulsar timing array observations
Gen Ye, Mian Zhu, Yong Cai
Recently, evidence of stochastic gravitational wave background (SGWB) signals observed by pulsar timing array (PTA) collaborations, has prompted investigations into their origins.…
