| Abstract: |
We present preliminary results from our ongoing single-dish and interferometric
molecular gas
survey toward a sample of optically selected merger remnants.
We show structural and kinematical evidence that a significant fraction
of merger remnants form rotating molecular disks around their central
remnants, and that the size of the resultant disks in some of the galaxies
are larger compared to the central bulge size inferred from the Sersic
radius. The high occurrence of disks in merger remnants may support
the evolutionary scenario where major mergers can evolve into a
variety of Hubble types. |
