Cosmological constraints on the big bang quantum cosmology model
Yicheng Wang, Yupeng Yang, Xinyi Dai +3
The big bang quantum cosmology model introduces the trace of the Schouten tensor as a form of dynamic dark energy. Together with cold dark matter, these components form the so-…
Redshift evolution of the Hubble constant: Constraints and new insights from an interacting dark energy model
Xinyi Dai, Yupeng Yang, Yicheng Wang +3
We develop a modified interacting dark energy (IDE) model to study the redshift evolution of the Hubble constant (), in light of the Hubble tension. In this framework, the ene…
Evidence of young magnetars in massive binary embedded in a supernova remnant as sources of active fast radio bursts
F. Y. Wang, H. T. Lan, Z. Y. Zhao +5
Fast radio bursts (FRBs) are intense pulses with unknown origins. A subclass of repeating FRBs show some common features, such as associated compact persistent radio sources (PRSs)…
The Hubble Tension resolved by the DESI Baryon Acoustic Oscillations Measurements
X. D. Jia, J. P. Hu, D. H. Gao +2
The cold dark matter (CDM) cosmological model provides a good description of a wide range of astrophysical and cosmological observations. However, severe challenges to the…
Calibrating relation using host galaxies of FRBs
Rui-Nan Li, Ke Xu, Dao-Hong Gao +3
Fast radio bursts (FRBs) are extragalactic radio transients that offer valuable insight of intergalactic medium (IGM). However, the dispersion measure (DM) contributed by IGM ($\rm…
Measuring Hubble constant using localized and unlocalized fast radio bursts
D. H. Gao, Q. Wu, J. P. Hu +4
The Hubble constant () is one of the most important parameters in the standard model. The measurements given by the main two methods show a gap larger than ,…
