First RM Grids Published!

The first prototype RM grids produced by the POSSUM pipeline have now been published, using data from pilot surveys in ASKAP’s low- and mid-frequency bands, and across two fields (one Galactic and one extragalactic). We project that when complete, POSSUM will catalog 0.8-0.9 million Faraday rotation measures (RMs).
