Impact of a negative cosmological constant on the reconstruction of dark energy in light of DESI BAO data
Hao Wang, Yun-Song Piao
An anti-de Sitter vacuum, corresponding to a negative cosmological constant (NCC), might coexist with one evolving positive dark energy component at low redshift and is hinted by t…
Dark energy after pre-recombination early dark energy in light of DESI DR2 and the latest ACT and SPT data
Hao Wang, Yun-Song Piao
It has been noted that with the pre-recombination early dark energy (EDE) resolution of Hubble tension, the preference of recent datasets for the evolving dark energy (DE) can be s…
Testing in light of the latest ACT and SPT data
Ze-Yu Peng, Jun-Qian Jiang, Hao Wang +1
It is commonly recognized that the primordial scalar spectral index is approximately , depending on the dataset. However, this view is being completely altered by…
Can the universe experience an AdS landscape since matter-radiation equality?
Hao Wang, Yun-Song Piao
Though an anti-de Sitter (AdS) vacuum, corresponding to a negative cosmological constant (NCC), can be not responsible for the acceleration of current universe, it might coexist wi…
Hint of after DESI DR2 ?
Hao Wang, Ze-Yu Peng, Yun-Song Piao
In the report by BICEP/Keck collaborations, the tensor-to-scalar ratio is (95\% C.L.). However, recent datasets have preferred the evolving dark energy, which thus…
Towards primordial gravitational waves and in light of BICEP/Keck, DESI BAO and Hubble tension
Hao Wang, Gen Ye, Jun-Qian Jiang +1
Recent observational data seem to show a evidence for an evolving dark energy (DE) against the cosmological constant, so the standard CDM model. In this paper, we p…
