Random Polarization Position Angle Behaviors across Bursts of Repeating Fast Radio Bursts
Xiaohui Liu, Jiarui Niu, Tiancong Wang +27
Fast radio bursts (FRBs), highly polarized, mostly have a nearly constant polarization position angle (PA) during each burst. Their PAs are observed to vary from burst to burst, wi…
To understand the radiative processes of pulsars and fast radio bursts with the FAST
Wei-Yang Wang, Shunshun Cao, Zhipeng Huang +39
The radiative mechanism of coherent radio emission has remained an enigma since the discovery of pulsars, even the emergence of fast radio bursts (FRBs), which exhibit similarities…
Long-term simultaneous 2.25/8.60~GHz monitoring of the newly-discovered repeating FRB~20240114A
Xiao-Wei Wang, Zhen Yan, Zhi-Qiang Shen +12
We report on the simultaneous monitoring of the repeating fast radio burst (FRB) 20240114A at 2.25 and 8.60~GHz, conducted 66 times between 2024 January 29 and 2025 February 15 wit…
H I absorption line and anomalous dispersion in the radio pulses of PSR B1937+21
Jinchen Jiang, Shunshun Cao, Kejia Lee +10
We use the Five-hundred-meter Aperture Spherical radio Telescope to observe the bright millisecond pulsar PSR B1937+21 (J1939+2134) and record the data in the band from 1.0 to 1.5…
Propagation-induced Frequency-dependent Polarization Properties of Fast Radio Burst
Wei-Yang Wang, Xiaohui Liu, Dongzi Li +6
Frequency-dependent polarization properties provide crucial insights into the radiation mechanisms and magnetic environments of fast radio bursts (FRBs). We explore an analytical s…
