Gemini/GMOS search of massive binaries in the ionizing cluster of 30 Dor
Guillermo Bosch, Elena Terlevich, Roberto Terlevich
If binaries are common among massive stars, it will have important consequences for the derivation of fundamental properties like the cluster age, IMF and dynamical mass. Making us…
Modelling Starburst in HII galaxies: From chemical to spectro-photometric evolutionary self-consistent models

The theory interest group in the International Virtual Observatory Alliance (IVOA) has the goal of ensuring that theoretical data and services are taken into account in the IVOA st…
The Role of Exploding QSOs in Explosive Models of Evolution, Formation and End of Galaxies
S. Lipari, M. Bergmann, S. F. Sanchez +7
In this work we analise the role and evidence of exploding BAL + IR + Fe II QSOs, and their relation with new -and previous- explosive models for evolution, formation and end of ga…

Daniel Rosa-Gonzalez, Denis Burgarella, Kirpal Nandra +3
We have combined multi-wavelength observations of a selected sample of starforming galaxies with galaxy evolution models in order to compare the results obtained for different SFR…
Kinematics of gas and stars in the circumnuclear starforming ring of NGC 3351
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
We have measured gas and stellar velocity dispersions in 5 circumnuclear starforming regions (CNSFRs) and the nucleus of the barred spiral galaxy NGC 3351. The stellar dispersions…
Gamow Legacy and the Primordial Abundance of Light Elements
E. Terlevich, R. Terlevich, V. Luridiana
The presently accepted "Theory of the Universe" was pioneered 60 years ago by Gamow, Alpher and Herman. As a consequence of the, later dubbed, Hot Big-Bang, matter was neutrons, an…
