PublicaciónConstraining the top-light initial mass function in the extended ultraviolet disk of M 83
Context. The universality or non-universality of the initial mass function (IMF) has significant implications for determining star formation rates and star...

PublicaciónConstraints to the masses of brown dwarf candidates form the lithium test
We present intermediate dispersion (0.7-2.2 A/pixel) optical spectroscopic observations aimed at applying the 'lithium test' to a sample of 10 brown dwarf...

PublicaciónDeep CCD photometry of stars in the globular cluster M3
CCD photometry of faint stars in the globular cluster M3 is presented. The observations reach down to V equal to about 23 mag, with a sample of approximately...

PublicaciónDensity waves and star formation in grand-design spirals
Context. H II regions in the arms of spiral galaxies are indicators of recent star-forming processes. They may have been caused by the passage of the density...

PublicaciónDetection and measurement of expanding ionized shells around young star clusters
We present a new method (BUBBLY) for detecting expanding components of ionized gas using integral field spectroscopy, showing its capabilities not only in...

PublicaciónDiversity of nuclear star cluster formation mechanisms revealed by their star formation histories
Nuclear star clusters (NSCs) are the densest stellar systems in the Universe and are found in the centres of all types of galaxies. They are thought to form via...

CharlaDusty supernovae running the thermodynamics of the matter reinserted by young stellar clusters
Following the observational and theoretical evidence that points at core collapse supernovae as major producers of dust, we calculate the hydrodynamics of the...
