Multiple-arm systems dominate, comprising $\\sim$50-60% of the sample and $\\sim$75% of large galaxies ($d_{\\rm max} \\geqslant 18~\\mathrm{kpc}$). In $90\\pm3$% of multiple-arm galaxies, two inner arms extend into…","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"],"authors":["Zehao Lin, Junye Wei, Ye Xu, Yingjie Li, Chaojie Hao, Dejian Liu, Yiwei Dong…"],"entities":[{"id":"Q1752705","name":"Milky Way","type":"place"}],"story":"st_od75xztvg35hsj2mfayq","category":"science-technology","category_p":0.6200000047683716,"sentiment":"neutral","tone":0.07999999821186066,"political":0.019999999552965164}]}
