Our analysis simultaneously fits the random-field structure, the synchrotron contributions of the coherent field and local foregrounds, and isotropic and dipolar offsets. A new element of the analysis is the use of excess polarized emission at 30 GHz to model local…","published":"2026-09-29T04:00:00Z","seen":"2026-09-29T07:46:41Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","astro-ph.ga","astro-ph.he"],"authors":["Michael Unger, Glennys R.
