Torsion cosmology in the light of DESI, supernovae and CMB observational constraints
Tonghua Liu, Xiaolei Li, Tengpeng Xu +2
In this work, we investigate a torsion-based cosmological model within the Einstei-Cartan framework, constrained by the latest combined datasets including DESI DR2 BAO, PantheonPlu…
Advancing Cosmological Parameter Estimation and Hubble Parameter Reconstruction with Long Short-Term Memory and Efficient-Kolmogorov-Arnold Networks
Jiaxing Cui, Marek Biesiada, Ao Liu +3
In this work, we propose a novel approach for cosmological parameter estimation and Hubble parameter reconstruction using Long Short-Term Memory (LSTM) networks and Efficient-Kolmo…
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…
Model independent calibration for sound horizon combining observations of supernovae and transversal BAO measurements
Tonghua Liu, Xinyi Zhong, Jieci Wang +1
The sound horizon is a key theoretical prediction of the cosmological model that depends on the speed of sound and the rate of expansion in the early universe, before matter and ra…
Model-independent way to determine the Hubble constant and the curvature from phase shift of gravitational waves with DECIGO
Tonghua Liu, Shuo Cao, Marek Biesiada +2
In this Letter, we propose a model-independent method to determine the Hubble constant and curvature simultaneously taking advantage of the possibilities of future space-borne grav…
