I have an Astronomy degree from
Observatório do Valongo - UFRJ (2002, the 142nd astronomer),
I have a PhD
on stellar populations of Early-type
galaxies from Physics Institute - UFRJ (2007).
I used spectroscopic data from
survey where I analyzed global
Lick indices and their Single Stellar Population ages and metallicities, as well as their
We confirmed the view that massive early-type galaxies formed long ago. Interestingly, they can have steep metallicity indices gradients, mimicking a "monolithic collapse" formation process.
