Galactic nuclei are special regions of galaxies, hosting supermassive
black holes and stellar populations that record important aspects of the
history of the galaxy formation and evolution. We will present the
DIVING3D project, an IFU/GMOS survey of a complete sample of 170 galaxies
in the southern hemisphere with B<12.0, δ<0 and |b|>15. Gemini
telescope time has been approved in the context of the Brazilian LLP (Long
and Large Projects) Program. We expect to achieve 5 scientific goals: a-
Nuclear emission line properties. Detect and study the statistical,
geometric and physical properties of Low Luminosity AGN: "dwarf"
Seyferts and LINERs as well as starburst nuclei. b- Circumnuclear emission
line properties. Determine the nature and ionization mechanism as well as
the kinematics of the line emitting gas in the ~100 pc scale circumnuclear
region. c- Stellar kinematical properties of all nuclei. Mass-to-light
ratios will be derived on dynamical basis and compared to those of
spectral synthesis and stellar velocity. d- Stellar populations
archeology. Study the chemical composition and history of star formation
using state-of the-art methods and stellar population models. e – Dust
and neutral gas. Study the distribution of these components in the nucleus
and circumnuclear region. The project is being observed in 5 sub-samples.
I will present the preliminary results of the first sub-sample: The
massive Early Type Galaxies.
