The thesis also offers unique guidance on using the Atacama Large Millimeter/submillimeter Array (ALMA) in active galactic nuclei (AGN) research. The author presents the three major findings regarding SMBH formation and growth: (1) The development of a new diagnostic method for the energy sources in galaxies based on submillimeter spectroscopy, which allows identification of accreting SMBHs even in obscured environments, (2) the discovery that the circumnuclear dense gas disk (CND), with a typical size of a few tens of parsecs, which plays a crucial role in governing the growth of SMBHs, and (3) the discovery that the mass transfer budget from the CND to the central SMBHs can be quantitatively understood with a theoretical model incorporating the circumnuclear starburst as a driver of mass transfer. The thesis skillfully reviews these three findings, which have greatly improved our understanding of the growth mechanism of SMBHs. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAstrophysics 606 $aCosmology 606 $aSpectroscopy 606 $aMicroscopy 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 606 $aSpectroscopy and Microscopy$3https://scigraph.springernature.com/ontologies/product-market-codes/P31090 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAstrophysics. 615 0$aCosmology. 615 0$aSpectroscopy. 615 0$aMicroscopy. 615 14$aAstronomy, Observations and Techniques. 615 24$aAstrophysics and Astroparticles. 615 24$aCosmology. 615 24$aSpectroscopy and Microscopy. 676 $a522 700 $aIzumi$b Takuma$4aut$4http://id.loc.gov/vocabulary/relators/aut$0835964 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300550103321 996 $aMillimeter and Submillimeter Studies on the Active Trinity of Gas, Stars, and Black Holes in Seyfert Galaxies$91868317 997 $aUNINA
