We model the effects of gas drag on the BHs' orbits, and allow BHs to grow via gas accretion, including a mode of hyper-Eddington accretion in which photon trapping and rapid gas inflow suppress any negative radiative feedback. Most initial BH configurations lead to the formation of one (but never more than one) IMBH in the center of the protogalaxy, reaching a mass of 10^3−5M⊙ through hyper-Eddington growth. Our results suggest a viable pathway to forming the earliest massive BHs in the centers of early galaxies. We also find that the nuclear IMBH typically captures a stellar-mass BH companion, making these systems observable in gravitational waves as extreme mass-ratio inspirals (EMRIs) with eLISA.","lang":"eng"}],"publication_status":"published","intvolume":"       460","article_processing_charge":"No","quality_controlled":"1","month":"05","scopus_import":"1","publication_identifier":{"issn":["0035-8711","1365-2966"]},"publication":"Monthly Notices of the Royal Astronomical Society","year":"2016","doi":"10.1093/mnras/stw1241","oa":1,"type":"journal_article","publisher":"Oxford University Press","citation":{"ista":"Ryu T, Tanaka TL, Perna R, Haiman Z. 2016.
