Bar-driven Spiral Structure: Statistical Study of Nearby Galaxies in OSUBSGS and NIRS0S Samples
We use the OSUBSGS (Ohio State University Bright Spiral Galaxy Survey, Eskridge et al. 2002) and NIRS0S (Near-IR S0 Survey, Laurikainen et al. 2005) data to study the connection of bars and outer spiral structures. Using near-IR images, the non-axisymmetric gravity perturbation associated with the bar is evaluated at various distances outside the
