A sudden dramatic change and recovery of magneto-environment of a repeating fast radio burst
Y. Li, S. B. Zhang, Y. P. Yang +35
Fast radio bursts (FRBs) are millisecond-duration radio bursts with unidentified extra-galactic origin. Some FRBs exhibit mild magneto-ionic environmental variations, possibly attr…
Hyper-active repeating fast radio bursts from rotation modulated starquakes on magnetars
Jia-Wei Luo, Jia-Rui Niu, Wei-Yang Wang +13
The non-detection of periodicity related to rotation challenges magnetar models for fast radio bursts (FRBs) with FRB emission from close to the magnetar surface. Moreover, a bimod…
Bright bursts with sub-millisecond structures of FRB 20230607A in a highly magnetized environment
DeJiang Zhou, J. L. Han, Bing Zhang +19
We report the observations of a repeating FRB 20230607A for 15.6 hours spanning 16 months using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) with the detection…
A universal break in energy functions of three hyperactive repeating fast radio bursts
Q. Wu, F. Y. Wang, Z. Y. Zhao +16
Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances with a mysterious origin. Observations show that at least some FRBs are produced by mag…
Follow-up timing of 12 pulsars discovered in Commensal Radio Astronomy FAST Survey
D. Zhao, J. P. Yuan, N. Wang +39
We present phase-connected timing ephemerides, polarization pulse profiles and Faraday rotation measurements of 12 pulsars discovered by the Five-hundred-meter Aperture Spherical r…
