The Takeaway
Fast Radio Bursts are usually rare, fleeting flashes that happen once and vanish. Finding a source that fires like a cosmic machine gun is exceptionally rare and allows astronomers to watch the environment around a 'repeater' change in real-time, providing a rare look at the extreme physics of the deep universe.
From the abstract
Polarization measurements of fast radio bursts (FRBs) probe the magnetized plasma surrounding their central engines. FRB~20240114A is an exceptionally active repeating source, with 17,356 bursts detected between 2024 January 28 and 2025 May 30 by FAST, enabling time-resolved polarimetric studies. In this work, we present a polarimetric catalog of 6,131 bright bursts (with a signal-to-noise ratio S/N $\geq$ 20, 35.3% of the total sample), including arrival time (MJD$_{\text{topo}}$), dispersion m
