[10.02] A WIYN Survey of Early-Type Barred Galaxies: Multiple Central Structures in Stars, Gas, and Dust

P. Erwin, L. S. Sparke, J. S. Gallagher (U. Wisconsin-Madison)

We will present initial results from a broadband optical survey of early-type barred galaxies with the WIYN 3.5m telescope. Our objective is to use the excellent seeing available at WIYN to find and characterize multiple central structures such as double bars, inner dust lanes, and emission-line gas. Double bars, in particular, are of interest, because they may be able to funnel gas efficiently into the nucleus of a galaxy, thereby feeding a nuclear starburst or an AGN. We will identify and distinguish non-axisymmetric structures in the gas, dust, and stars of these galaxies, and relate such structures to the dynamical and evolutionary predictions made by models of gas flows and stellar populations.
