| Abstract: |
The existence of mass components having opposite angular momentum in disk galaxies has been reported mainly for early type spirals. We have undertaken an observational and theoretical study of counterrotating gaseous disks to understand the evolution of mass-accreting systems. On the observational side, we have completed CO interferometer observations in two early type spirals: NGC 3626, and NGC 3593. The long-standing evolution of counterrotating gaseous disks, and specially their main dynamical instabilities (m=1 and m=2 modes) are analysed via numerical simulations of the clouds hydrodynamics. |
