Cosmology with fast radio bursts in the era of SKA
Ji-Guo Zhang, Ze-Wei Zhao, Yichao Li +3
We present a forecast of the cosmological parameter estimation using fast radio bursts (FRBs) from the upcoming Square Kilometre Array (SKA), focusing on the issues of dark energy,…
Fast radio burst energy function in the presence of variation
Ji-Guo Zhang, Yichao Li, Jia-Ming Zou +3
Fast radio bursts (FRBs) have been found in great numbers, but the physical mechanism of these sources is still a mystery. The redshift evolutions of the FRB energy distribution fu…
FRB dark sirens: Measuring the Hubble constant with unlocalized fast radio bursts
Ze-Wei Zhao, Ji-Guo Zhang, Yichao Li +2
Fast radio bursts (FRBs) can be used to measure cosmological parameters by employing the Macquart relation. However, at present, only a small number of FRB events are localized to…
Probing the interaction between dark energy and dark matter with future fast radio burst observations
Ze-Wei Zhao, Ling-Feng Wang, Ji-Guo Zhang +2
Interacting dark energy (IDE) scenario assumes that there exists a direct interaction between dark energy and cold dark matter, but this interaction is hard to be tightly constrain…
A forecast of using fast radio burst observations to constrain holographic dark energy
Xing-Wei Qiu, Ze-Wei Zhao, Ling-Feng Wang +2
Recently, about five hundred fast radio bursts (FRBs) detected by CHIME/FRB Project have been reported. The vast amounts of data would make FRBs a promising low-redshift cosmologic…
Relieving the tension with a new interacting dark energy model
