We find that before the Strömgren spheres of the individual ionizing sources overlap, the UV background below the ionization threshold is able to penetrate large clouds and suppress their H2 abundance. The consequent lack of H2 cooling could prevent the collapse and fragmentation of clouds with virial temperatures Tvir ≲ 10^4 K (or masses ≲10^8 M☉[(1 + zvir)/10]-^3/2). This negative feedback on structure formation arises from the very first ionizing sources and precedes the feedback due to the photoionization heating.","lang":"eng"}],"day":"20","title":"Destruction of molecular hydrogen during cosmological reionization","publication_status":"published","article_processing_charge":"No","date_created":"2024-09-06T11:51:44Z","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"oa":1,"intvolume":"       476","OA_place":"repository","publisher":"American Astronomical Society","oa_version":"Preprint","OA_type":"green","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.astro-ph/9608130","open_access":"1"}],"author":[{"orcid":"0000-0003-3633-5403","full_name":"Haiman, Zoltán","first_name":"Zoltán","last_name":"Haiman","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36"},{"full_name":"Rees, Martin J.","first_name":"Martin J.","last_name":"Rees"},{"full_name":"Loeb, Abraham","last_name":"Loeb","first_name":"Abraham"}],"citation":{"ista":"Haiman Z, Rees MJ, Loeb A. 1997.
