Ten Thousand Fast Radio Bursts Could Map Cluster Magnetism
Current stacks set microgauss-scale upper limits; a future DSA sample could measure group fields to 3–13 percent precision.
Summary
Current stacks set microgauss-scale upper limits; a future DSA sample could measure group fields to 3–13 percent precision.
The study combines Faraday rotation, fast-radio-burst dispersion, kinematic Sunyaev-Zel'dovich and thermal-pressure constraints. Present data yield upper limits, not detections. Forecasts indicate a denser Deep Synoptic Array rotation grid plus 10,000 bursts could make precision profiles possible.
Why it matters
Current stacks set microgauss-scale upper limits; a future DSA sample could measure group fields to 3–13 percent precision.
