TÍTULO

Recovering the origin of Lenticular Galaxies from stellar kinematics and 
multi-wavelengths surveys.


RESUMEN

Recent results from IFU surveys, as SAURON and Califa, changed our view 
of galaxy classification, proposing to use the kinematic balance between 
rotation and random motion in a galaxy, in order to classify galaxies 
into fast and slow rotators; with some of the fast rotators presenting 
spiral arms. In this new view, lenticular galaxies, which traditionally 
fall at the apex of the Hubble tuning fork, between elliptical and 
spiral galaxies, will naturally fall in the fast-rotator group. It is 
now to be understood if all fast rotators are lenticular galaxies or 
whether there are different path to create fast rotators and even 
lenticular galaxies. In this talk I will present results from planetary 
nebulae and globular clusters kinematics to tackle this issue. I will 
show some attempt to use multi-band images to identify parameter that 
can be use to classify galaxies and I will  introduce a new 
Brazilian-Spanish survey (J-PAS), that will observe the northern sky in 
56 filters, and the south and north hemisphere in 12 filters (S-PLUS and 
J-PLUS).
