PublicationFaint 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...

PublicationField 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...

PublicationFirst steps of the GTC photometric calibration plan
Large telescopes require a very precise calibration in order to maximize its scientific output. Current catalogues of standard stars are generally too bright...

PublicationFormation 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...

PublicationFrom blue cloud to red sequence: evidence of morphological transition prior to star formation quenching
We present a study of a sample of 254 clusters from the SDSS-DR7 Yang Catalogue and an auxiliary sample of field galaxies to perform a detailed investigation on...

PublicationFrom kpcs to the central parsec of NGC 1097: feeding star formation and a black hole at the same time
A panchromatic view of the star-forming ring and feeding process in the central kpc of the galaxy NGC 1097 is presented. The assembled IR to UV images at ˜10 pc...
