Investigating the Anisotropy of Dispersion Measure Contribution from the Galactic Halo by Using Fast Radio Bursts
Yang Liu, Bao Wang, Puxun Wu +2
We propose a data-driven approach to reconstruct the all-sky distribution of the dispersion measure contribution from the Galactic halo () through a spherical h…

Photon rest mass from localized fast radio bursts with improved distribution of dispersion measure from extragalactic gas
Yuchen Zhang, Yang Liu, Hongwei Yu +1
The assumption that photons are massless is a foundational postulate of modern physics, yet it remains subject to experimental verification. Fast radio bursts (FRBs), with their co…

Probability density function for dispersion measure of fast radio burst from extragalactic medium
Yuchen Zhang, Yang Liu, Hongwei Yu +1
Fast Radio Bursts (FRBs) have emerged as powerful probes in cosmology. An optimized method was recently proposed to extract the cosmic baryon density from localized FRBs by maximiz…
