CharlaEvolution of barred galaxies. A model for the Milky Way bar and bulge in this context
Among the different effects of secular evolution of galaxies we find how bars influence enormously their host galaxies. For many years now, it is known how the...

CharlaExploring the local universe with massive stars
Massive stars dominate the light output of entire galaxies, with luminosities in excess of 10 5 L⊙. This makes them powerful probes with which to study a range...

CharlaGalactic Dynamics to Explain Outer Disc Features in Spiral Galaxies
Milky Way and most spiral galaxies present some features in the outer part of its disk such as S-warping or U-warping, flaring, lopsidedness, truncation/non...

CharlaModels of our Galaxy: why, how and what they do for us
The study of the Milky is expected to have a major impact on our understanding of how galaxies form and evolve. "Near-field cosmology" is being vigorously...

CharlaOn the age of the Milky Way bulge stellar population
The Milky Way (MW) galaxy is not much different from its faraway cousins. However, our position within the MW allows us to study the properties of its stellar...

CharlaOur Galaxy in its infancy as traced by Gaia and complementary spectroscopic surveys
Reconstructing the past of the Milky Way depends on the study of its metal-poor stars, which either have been formed in the Galaxy itself in the first billion...

CharlaPristine stars in the Milky-Way and beyond
To understand the early phases of galaxy formation, metal-poor stars in the local universe play a special rôle, allowing to trace both how galactic assembly...
