Exploring the brightest: the hunt for the most luminous infrared galaxies in the UniverseAbstract
Hyper-luminous infrared (IR) galaxies (HyLIRGs) are among the most luminous objects in the Universe. Their IR luminosity exceeds 10^13 solar luminosities, produced by significant star formation (SF), active galactic nuclei (AGN), or both. HyLIRGs are thought to probe the maximum growth phase for supermassive black holes (SMBHs) and their host galaxies during galaxy-SMBH co-evolution. Because HyLIRGs are an extremely rare population, their physical properties need to be better understood. We have conducted an intensive search for HyLIRGs in the past few years using multi-wavelength data. In this talk, I will introduce how to hunt these extremely luminous monsters in the Universe and present their revealed physical properties (e.g., Toba et al. 2018; 2020; 2022; 2024).
