Our deep NIRSpec/\r\nG395M spectroscopy reveals unambiguous broad Balmer emission (FWHM = 2221 ± 20 km s\r\n−1\r\n), confirming a\r\nsuper-Eddington accreting black hole (BH) (λEdd = 2.7 ± 0.4) with a mass of\r\nlog(MBH/M ) = 7.55 ± 0.34,\r\nusing accretion-rate-corrected BH mass estimators. After subtracting the point source, we robustly detect stellar\r\nemission from the host galaxy across multiple NIRCam and MIRI filters. Our joint morphological-spectral\r\nanalysis yields a stellar mass of = ± * log(M /M ) 10.5 0.4\r\nand an intense star formation rate of\r\nSFR = 330 ± 97 M⊙ yr−1\r\n, confirming the host as a massive, dusty starburst galaxy. We find that GNz7q lies\r\non the local MBH–M* relation (MBH/M* ≃ 0.001) and is well positioned to evolve into the locus of massive Sloan\r\nDigital Sky Survey (SDSS) quasars with\r\nlog(MBH/M ) 9\r\nand M* ≈ 1011 M⊙ at z ∼ 6, owing to its remarkably\r\nrapid growth in both the BH and its host galaxy. This stands in stark contrast to many recently reported JWST\r\nactive galactic nucleus populations at similar redshifts, including the little red dots, whose weak or undetected star\r\nformation makes it difficult for them to grow into the massive galaxies hosting SDSS-like quasars. These results\r\nsuggest that GNz7q marks a rare, pivotal phase of early BH–galaxy coevolution, plausibly providing a crucial\r\ndirect pathway to the supermassive BH systems within the first billion years of the Universe."}],"volume":1010,"fulldoi":"https://doi.org/10.3847/1538-4357/aea07b","type":"journal_article","file":[{"date_updated":"2026-10-19T06:36:24Z","content_type":"application/pdf","date_created":"2026-10-19T06:36:24Z","success":1,"access_level":"open_access","relation":"main_file","file_name":"2026_AstrophysicalJour_FeiQinyue.pdf","creator":"dernst","checksum":"b319631e496b3f50fd32202bb19a5b99","file_id":"23162","file_size":3985652}],"year":"2026","date_published":"2026-10-10T00:00:00Z","language":[{"iso":"eng"}],"oa":1,"oa_version":"Published Version","das_tickbox":"1","article_processing_charge":"Yes","researchdata_availability":"yes","file_date_updated":"2026-10-19T06:36:24Z","dataavailabilitystatement":"The reduced 1D NIRSpec/G395M spectra, the MIRI LRS 1D extraction, and the MIRI MRS 1D extraction used in this work are publicly available on Zenodo at DOI: 10.5281/zenodo.21539999.\r\nFacilities: JWST - James Webb Space Telescope, IRAM:NOEMA. -\r\nSoftware: GalfitS (R.
