We investigate when and how a dusty starburst galaxy merger can be heavily obscured by dust and consequently becomes an ultra-luminous infrared galaxy (ULIRG), based on numerical simulations of chemodynamical and photometric evolution of dusty gas-rich major galaxy mergers. We found that a major galaxy merger is more likely to become an ULIRG preferentially in the merger late phase, when the two disks become very close and the very high-density dusty gas can obscure heavily the central… CONTINUE READING
