Our results show that cooling accelerates the collapse of the X-point along the inflows, but strong cooling can arrest or even reverse the current sheet elongation in the outflow direction. Hence, we detail a modification to the radiatively cooled Sweet\u2013Parker model developed by Uzdensky\u00a0&amp; McKinney (\n                    <jats:italic>Phys.

The steady-state solution shows that, when radiative cooling dominates compressional heating, the current sheet length is shorter than the system size, with an increased reconnection rate compared with the classical Sweet\u2013Parker rate. The model and subsequent results lay out the groundwork for a more complete theoretical understanding of magnetic reconnection in regimes dominated by optically thin radiative cooling.\n                  <\/jats:p>","DOI":"10.1017\/s0022377825100949","type":"journal-article","created":{"date-parts":[[2025,11,7]],"date-time":"2025-11-07T07:01:05Z","timestamp":1762498865000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Current sheet formation under radiative cooling"],"prefix":"10.1017","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1806-0953","authenticated-orcid":false,"given":"Simran","family":"Chowdhry","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/042nb2s44","id-type":"ROR","asserted-by":"publisher"}],"name":"Massachusetts Institute of Technology"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9755-6563","authenticated-orcid":false,"given":"Nuno F.","family":"Loureiro","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/042nb2s44","id-type":"ROR","asserted-by":"publisher"}],"name":"Massachusetts Institute of Technology"}]}],"member":"56","published-online":{"date-parts":[[2025,11,7]]},"reference":[{"key":"S0022377825100949_ref7","first-page":"435","article-title":"Liquid instability and energy transformation near a magnetic neutral line: a soluble non-linear hydromagnetic problem","volume":"271","author":"Chapman","year":"1963","journal-title":"Proc.
