Probing the ULIRG-to-QSO evolution

Focusing on extragalactic astronomical objects, the study explores the evolutionary relationship between ULIRGs and QSOs, suggesting that ULIRGs serve as the dust-enveloped progenitors of QSOs. By analyzing observational data and simulations across radio and millimeter wavelengths, the research examines a sample of galaxies with active galactic nuclei. It particularly emphasizes Arp220 as a representative of early evolutionary stages, while nearby QSOs illustrate the later phases, investigating their emissions and merger dynamics.
