Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…

Ninety percent circular polarization detected in a repeating fast radio burst
J. C. Jiang, J. W. Xu, J. R. Niu +34
Fast radio bursts (FRBs) are extra-galactic sources with unknown physical mechanisms. They emit millisecond-duration radio pulses with isotropic equivalent energy of $10^{36}\sim10…

HiFAST: An HI Data Calibration and Imaging Pipeline for FAST III. Standing Wave Removal
Chen Xu, Jie Wang, Yingjie Jing +13
The standing waves existed in radio telescope data are primarily due to reflections among the instruments, which significantly impact the spectrum quality of the Five-hundred-meter…
