Inflation driven by a bare cosmological constant and its graceful exit
Chengsheng Mu, Shuxun Tian, Shuo Cao +1
Vacuum energy, a prediction of quantum field theory, manifests itself as a cosmological constant in general relativity. In this Letter, we propose a novel inflationary scenario dri…
Testing Screened Modified Gravity with Strongly Lensed Gravitational Waves
Chengsheng Mu, Shuo Cao, Shuxun Tian +3
Screening mechanisms are essential components in many modified gravity theories, which satisfy local tests of General Relativity (GR) and address cosmic acceleration on cosmologica…
New tests of cosmic distance duality relation with DESI 2024 BAO observations
Qiumin Wang, Shuo Cao, Jianyong Jiang +5
In this paper, we test the cosmic distance duality relation (CDDR), as required by the Etherington reciprocity theorem, which connects the angular diameter distance and the luminos…
Newest measurements of Hubble constant from DESI 2024 BAO observations
Wuzheng Guo, Qiumin Wang, Shuo Cao +6
In this Letter, we use the latest results from the Dark Energy Spectroscopic Instrument (DESI) survey to measure the Hubble constant. Baryon acoustic oscillation (BAO) observations…
