Several suggested formation pathways for these SMBHs lead to a heavy seed, with an initial black hole mass of 104–106 M⊙. This can lead to an overly massive BH galaxy (OMBG), whose nuclear black hole’s mass is comparable to or even greater than the surrounding stellar mass: the black hole to stellar mass ratio is Mbh/M* ≫ 10−3, well in excess of the typical values at lower redshift. We investigate how long these newborn BHs remain outliers in the Mbh − M* relation, by exploring the subsequent evolution of two OMBGs previously identified in the Renaissance simulations. We find that both OMBGs have Mbh/M* &amp;gt; 1 during their entire life, from their birth at z ≈ 15 until they merge with much more massive haloes at z ≈ 8. We find that the OMBGs are spatially resolvable from their more massive, 1011 M⊙, neighbouring haloes until their mergers are complete at z ≈ 8. This affords a window for future observations with JWST and sensitive X-ray telescopes to diagnose the heavy-seed scenario, by detecting similar OMBGs and establishing their uniquely high black hole-to-stellar mass ratio.","lang":"eng"}],"publication_status":"published","issue":"2","language":[{"iso":"eng"}],"article_type":"original","date_published":"2022-12-20T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.1093/mnras/stac3715","open_access":"1"}],"status":"public","day":"20","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-05T12:14:22Z","author":[{"full_name":"Scoggins, Matthew T","first_name":"Matthew T","last_name":"Scoggins"},{"full_name":"Haiman, Zoltán","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"},{"last_name":"Wise","full_name":"Wise, John H","first_name":"John H"}],"page":"2155-2168","date_updated":"2024-09-19T07:18:22Z","citation":{"mla":"Scoggins, Matthew T., et al. “How Long Do High Redshift Massive Black Hole Seeds Remain Outliers in Black Hole versus Host Galaxy Relations?” <i>Monthly Notices of the Royal Astronomical Society</i>, vol. 519, no. 2, Oxford University Press, 2022, pp. 2155–68, doi:<a href=\"https://doi.org/10.1093/mnras/stac3715\">10.1093/mnras/stac3715</a>.","ieee":"M.
