Gas Flows in the Inner Kiloparsec of NGC 1386
Abstract
What are the mechanisms that funnel gas from the inner kpc of an active galaxy (AGN) down to the central super-massive black hole (SMBH)? Is there any relation between the SMBH accretion rate and the mass in/outflow rate? To answer these questions we are studying a sample of nearby AGN spanning a wide range of nuclear X-ray luminosity (a proxy for the SMBH accretion rate). Here we present results of a detailed analysis of the ionized gas kinematics in the inner kpc of NGC 1386, a nearby Seyfert 2. Data have been obtained with the GMOS integral field unit on the GEMINI South telescope at a spatial resolution of ~70 pc and a spectral resolution of ~50 km/s. Previous HST narrow-band imaging observations suggested the presence of a bipolar outflow. However, our velocity maps show that these features are consistent with a rotating large-scale disk extending over ~300 pc in radius and illuminated by the AGN radiation cone, whilst the inner 100 pc is dominated by a wide-angle outflow whose axis is roughly perpendicular to the cone.
