Abstract

We present two-dimensional stellar and gaseous kinematics of the inner 119 × 255 pc2 of the LINER/Seyfert 1 galaxy M 81 on the basis of observations obtained with the Integral Field Unit of the Gemini Multi-Object Spectrograph (GMOS-IFU) on the Gemini North telescope at a spatial resolution of ~10 pc, over the wavelength range 5600–7000 Å. Our goal is to map the gas-streaming motions toward the nucleus suggested by the presence of a dusty nuclear spiral previously observed in HST images (Simões Lopes et al. 2007). Such structures have been shown to be associated with inward gas motions in previous studies by our group (Fathi et al. 2006; Storchi-Bergmann et al. 2007).
