FAST FRB 20240114A Polarization Catalog
Listed in ScienceDB
In this catalog, we present the high-precision polarization catalog of the repeating FRB 20240114A from FAST monitoring (from 2024 January 28 to 2025 May 30), comprising 6,131 bursts with S/N > 20.
Description
The catalog provides arrival time, dispersion measure, burst width, bandwidth and full polarimetric properties, including Faraday rotation measure (RM) for individual bursts. Analysis reveals a rapidly evolving magneto-ionic environment: the RM decayed linearly by ~200 rad m-2 over 200 days after an initial stable phase, producing a bimodal distribution.
Intrinsic polarization angles show a broad, non-uniform distribution, and RM is uncorrelated with DM, indicating environmental complexity. The data, which is released publicly, offer a foundational resource for studying FRB progenitors and environments.
