Testing the Isotropy of the Universe with the CHIME/FRB Catalog I
Jun-Yi Shen, Yuan-Chuan Zou
The paper examines whether the distribution of 536 fast radio bursts from the CHIME/FRB catalog is isotropic across the sky, using two-point angular correlation and sigma‑map analy…

Revisiting the Reported Period of FRB 20201124A Using MCMC Methods
Jun-Yi Shen, Yuan-Chuan Zou
Fast radio bursts (FRBs) are millisecond-duration radio transients whose physical origin remains uncertain. Magnetar-based models, motivated by observed properties such as polariza…

Measuring the curvature of the universe based on the dust-scattering ring of GRB 221009A
Jun-Yi Shen, Yuan-Chuan Zou
We investigate the use of dust-scattering rings from GRB 221009A to measure cosmic curvature. We derive the relationship between scattering angle and time delay in non-flat univers…
