Molecular Gas and Dust in ULIRGs : SMA view
Ultraluminous Infrared Galaxies (ULIRGs) are merging galaxies
with extremely vigorous starburst or quasar-class AGNs. Local
ULIRGs may be $z \sim 0$ analogs of the merging events that many
galaxies experienced during their assembly process. If so, we can
study in local ULIRGs the interplay of gas content, star formation,
and AGN activities in detail in the important period when galaxies
rapidly evolve. I am going to review recent observations of molecular
gas and dust in ULIRGs made using the Submillimeter Array (SMA).
The submillimeter-capability and high-resolution of the SMA give
us a glimpse of how the ALMA will transform our understanding of ULIRGs.
