Title:Nuclear and circum-nuclear low ionization emission in massive galaxies
PI:Tiago Ricci
Co-I(s): João Steiner, Roberto Menezes

Abstract

We propose to observe a statistically complete sample of massive galaxies (B < 12.0 mag and σ > 200 km / s ) in the southern hemisphere. Such objects are known to frequently present both nuclear and circum-nuclear low ionization emission lines. Many questions still remain to be answered and will be addressed by this survey, such as: 1- What is the frequency of galaxies without an AGN? Are there massive galaxies without a central supermassive black hole? 2- What is the frequency of circum-nuclear low ionization emission? How does the circum-nuclear emission relate to the AGN and to the stellar population and galaxy properties? What is the kinematics associated with the circum-nuclear emission? 3- What is the frequency and characteristics of the broad component in Hα and [O I] lines and how do they relate to other parameters? In addition we will derive properties of the stellar component to obtain Gauss-Hermite moments, characterize fast and slow rotators and correlate them with environment. For the most promising cases we will also derive the mass of the black hole.
