One possibility is that stellar-mass ``seed'' BHs, left behind by the first stars, accrete gas at close to the Eddington limit during a large fraction (>~ 50%) of the time. While maintaining such a high accretion rate may itself be difficult, here we focus on another, less commonly discussed problem in this scenario: unless BH seed formation and growth are preferentially suppressed in less massive protogalaxies, the mass density in M~106Msolar SMBHs at z ~ 6 already exceeds the locally observed SMBH mass density by several orders of magnitude. We show that the X-rays from the earliest accreting BHs themselves can cause a self-regulation, by partially ionizing and heating the intergalactic medium (IGM). This ``global warming'' suppresses the formation and growth of subsequent generations of BHs in low-mass halos, and can produce excellent agreement with recent estimates of the z = 6 SMBH mass function, without impeding the growth of the largest (M>~109Msolar) holes, which reside in the most massive galaxies that formed first. The proposed gravitational-wave observatory eLISA could detect several tens of major mergers between SMBHs at z > 6."}],"publication_status":"published","type":"conference","publisher":"American Institute of Physics","article_processing_charge":"No","main_file_link":[{"url":"https://doi.org/10.1063/1.4754372"}],"month":"09","scopus_import":"1","day":"12","quality_controlled":"1","status":"public","language":[{"iso":"eng"}],"doi":"10.1063/1.4754372","publication_identifier":{"issn":["0094-243X"]},"date_published":"2012-09-12T00:00:00Z","publication":"AIP Conference Proceedings","year":"2012","author":[{"first_name":"Zoltán","full_name":"Haiman, Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"},{"last_name":"Tanaka","full_name":"Tanaka, Takamitsu","first_name":"Takamitsu"},{"last_name":"Perna","full_name":"Perna, Rosalba","first_name":"Rosalba"}],"page":"303-308","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-06T07:29:59Z"}
