PublicaciónA unified model for age-velocity dispersion relations in Local Group galaxies: disentangling ISM turbulence and latent dynamical heating
We analyse age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ˜ 106 M⊙)...

PublicaciónAGB and RGB stars as tracers of the early and intermediate star-formation history.
The Milky Way and Andromeda galaxies are the largest members of the Local Group, and their evolution is affected by the evolution of their host as a whole. At...

PublicaciónAGN Activity and Circumnuclear Star Formation in Nearby Galaxies
We have selected a sample of nearby galaxies where an AGN (Seyfert or LINER) coexists with circumnuclear star formation. We use the highest spatial resolution...

CharlaAGN activity in Local Luminous Infrared Galaxies
Luminous Infrared Galaxies (LIR=10^11-10^12Lsun) have star formation rates in the range of ~20-200Msun/yr. In the local Universe ~50% LIRGs show AGN or AGN/SB...
