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…
Impact of evolving dark energy on the search for primordial gravitational waves
Hao Wang, Gen Ye, Yun-Song Piao
Recent data seem to suggest a preference for the evolving dark energy (DE). However, if the case is actually so, and not caused by unknown systematics in data, it might impact our…
Can recent DESI BAO measurements accommodate a negative cosmological constant?
Hao Wang, Ze-Yu Peng, Yun-Song Piao
Anti-de Sitter vacuum, which correspond to a negative cosmological constant (CC), is theoretically important and well-motivated. However, whether it exists in reality or not has al…
Dark energy in light of recent DESI BAO and Hubble tension
Hao Wang, Yun-Song Piao
Recently, Dark Energy Spectroscopic Instrument (DESI) collaboration based on their first year data has reported a evidence for an evolving dark energy (DE) against the…
Trapped early dark energy
Hao Wang, Yun-Song Piao
As a prospective resolution of the Hubble tension, early dark energy (EDE) suffers from the coincidence problem, why EDE is active just at matter-radiation equality (equivalently w…
