Powerful Outflows in Seyfert Galaxies : Wind- Vs. Jet-Driven Models
MetadataShow full item record
Seyfert galaxies are active galaxies characterized by luminous outflows from a central super massive black hole. The outflow mechanism has not been fully determined, but the two primary competing systems are a wind-driven conical outflow and a jet-driven cylindrical outflow. We are developing models with a variety of parameters, including inclination, cone opening angle, etc. By varying these parameters, we can add detail to the model to more completely match the observed velocities. We compare the models to the Hubble Space Telescope long-slit spectra of the Seyfert galaxies NGC 1068 and NGC 4151 in an effort to more fully understand the actual outflow mechanism of these galaxies.
