A chain theorem for planar PM-compact bricks
Yaxian zhang, Qiuli Li, Fuliang Lu
A connected graph is matching covered if it contains at least one edge and every edge belongs to some perfect matching of . A matching covered graph is a brick if it is 3-co…
Unveiling the spectral morphological division of fast radio bursts with CHIME/FRB Catalog 2
Wan-Peng Sun, Yin-Long Cao, Yong-Kun Zhang +7
Fast radio bursts (FRBs) are commonly classified into repeating and apparently nonrepeating sources, yet whether this distinction reflects intrinsically different physical populati…
Simultaneous determination of Hubble constant and cosmic baryon density: Forecasts for the synergy between FRBs and emerging probes
Peng-Ju Wu, Bo-Yang Zhang, Ji-Guo Zhang +3
Two of the most pressing challenges in cosmology are the persistent discrepancy in measurements of the Hubble constant, referred to as the Hubble tension, and the deficit of baryon…
A Practical Framework for Estimating the Repetition Likelihood of Fast Radio Bursts from Spectral Morphology
Wan-Peng Sun, Yong-Kun Zhang, Ji-Guo Zhang +6
The repeating behavior of fast radio bursts (FRBs) is regarded as a key clue to understanding their physical origin, yet reliably distinguishing repeaters from apparent non-repeate…
Cosmic baryon census with fast radio bursts and gravitational waves
Ji-Guo Zhang, Ji-Yu Song, Wan-Peng Sun +3
The cosmic baryon density fraction () is intrinsically correlated with the Hubble constant () through the critical density of the Universe. In the context of the de…
Combining strongly lensed and unlensed fast radio bursts: To be a more precise late-universe probe
Ji-Guo Zhang, Yi-Fan Jiang, Ze-Wei Zhao +3
The Macquart relation and time-delay cosmography are now two promising ways to fast radio burst (FRB) cosmology. In this work, we propose a joint method that combines strongly lens…
Exploring the Key Features of Repeating Fast Radio Bursts with Machine Learning
Wan-Peng Sun, Ji-Guo Zhang, Yichao Li +4
Fast radio bursts (FRBs) are enigmatic high-energy events with unknown origins, which are observationally divided into two categories, i.e., repeaters and non-repeaters. However, t…
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…
