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…

Reconstructing the Anisotropic Ultra-long Wavelength Spectra using a Single Antenna on Lunar-orbit
Qige Ao, Furen Deng, Yidong Xu +3
The ultra-long wavelength sky ( MHz) is still largely unexplored, as the electromagnetic wave is heavily absorbed and distorted by the ionosphere on Earth. The far-s…
