PublicaciónFaint C and O recombination lines in H II regions and large telescopes: The case of S311
We present preliminary results on the analysis of very deep echelle UVES (8m VLT) spectra of the Galactic H II region S311 (NGC 2467) located outside the Solar...

PublicaciónField O stars: formed in situ or as runaways?
A significant fraction of massive stars in the Milky Way and other galaxies are located far from star clusters and star-forming regions. It is known that some...

PublicaciónFormation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...
