We show that the release of the gravitational binding energy, over the halo assembly timescale, results in a significant and detectable Lyα flux. At the limiting line flux ≈10^-19 ergs s^-1 cm^-2 arcsec^-2 of the Next Generation Space Telescope, several sufficiently massive halos, with velocity dispersions σ ≳ 120 km s^-1, would be visible per 4' × 4' field. The halos would have characteristic angular sizes of ≈10'', would be detectable in a broadband survey out to z ≈ 6-8, and would provide a direct probe of galaxies in the process of forming. They may be accompanied by He+ Lyα emission at the ≈10% level, but remain undetectable at other wavelengths. Our predictions are in good agreement with the recent finding of two Lyα \"blobs\" at z = 3.1 by Steidel et al.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.astro-ph/0003366"}],"date_updated":"2024-11-13T07:41:20Z","month":"07","status":"public","article_type":"original","oa":1,"external_id":{"arxiv":["astro-ph/0003366"]},"OA_place":"repository","page":"L5-L8","quality_controlled":"1","publisher":"American Astronomical Society","OA_type":"green","day":"01","publication":"The Astrophysical Journal","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1086/312754","arxiv":1,"issue":"1","extern":"1","publication_status":"published","date_created":"2024-09-06T12:15:30Z","intvolume":" 537","publication_identifier":{"issn":["0004-637X"]},"year":"2000","scopus_import":"1","author":[{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán","orcid":"0000-0003-3633-5403"},{"first_name":"Marco","last_name":"Spaans","full_name":"Spaans, Marco"},{"full_name":"Quataert, Eliot","first_name":"Eliot","last_name":"Quataert"}]}
