GMOS IFU observations of the stellar and gaseous kinematics in the centre of NGC 1068

Abstract

We present a datacube covering the central 10 arcsec of the archetypal active galaxy NGC 1068 over a wavelength range 4200 to 5400 Angstrom. obtained during the commissioning of the integral field unit (IFU) of the Gemini Multiobject Spectrograph (GMOS) installed on the Gemini-North telescope. The datacube shows a complex emission line morphology in the [OIII] doublet and Hbeta line. To describe this structure phenomenologically we construct an atlas of velocity components derived from multiple Gaussian component fits to the emission lines. The atlas contains many features which cannot be readily associated with distinct physical structures. While some components are likely to be associated with the expected biconical outflow, others are suggestive of high velocity flows or disk-like structures. As a first step towards interpretation, we seek to identify the stellar disk using kinematical maps derived from the Mgb absorption line feature at 5170 Angstrom and make associations between this and gaseous components in the atlas of emission line components.
