Star formation properties and dynamics of Luminous Infrared Galaxies with adaptive optics

2009
Near infrared adaptive opticsobservations are crucial to be able to interpret kinematic and dynamical dataand study star formationproperties within the often extremely dustyinteracting luminous IR galaxies (LIRGs). NIR AO data are also needed to find supernovae in their bright and dustycentral regions and to fully characterize the young stellar clusters found in these kinds of systems. We have used AO in the K-bandto survey a sample of LIRGs at 0.1 arcsec (30 to 100 pc) resolution. The data are merged with SALT and AAT spectroscopic follow-up and HST and Spitzer archival imaging. The first AO detected SNe are reported as well as details of the first studied LIRGs. One LIRG showed an unexpected third component in the interaction, which moreover turned out to host the most active star formation. Another target showed evidence in the NIR of a very rare case of leading spiral arms, rotating in the same direction as the arms open.
