HST Long Slit Spectroscopy of NGC 1068 and NGC 4151
NGC 1068 annd NGC 4151 are Seyfert Galaxies, the most common type of active galaxy, in which a luminous nucleus is powered by accretion onto a massive black hole at its center. Seyfert galaxies are known to exhibit high ...
Powerful Outflows in Seyfert Galaxies : Wind- Vs. Jet-Driven Models
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 ...
The Faber-Jackson relation in Seyfert galaxies
Seyfert galaxies, in which accretion onto a massive nuclear black hole acts as a powerful energy source, allegedly have bulges more luminous per unit mass than those in normal galaxies. We have tested this claim through ...
Hubble space telescope imaging of seyfert galaxies
Recent searches for massive black holes in galactic nuclei show that they are common if not ubiquitous. Furthermore, there are important relationships between black hole mass and properties characterizing the size and ...
"Faber-Jackson relation in Seyfert galaxies"
Previous investigations have indicated that the bulges of Seyfert galaxies are more luminous than those in normal galaxies of the same mass. This may result if Seyfert bulges have experienced recent star formation, perhaps ...
