Given their low surface brightness, it is hard to determine high-quality spectra of dwarf galaxies outside the Local Group, where it is not possible to study the individual stars. Although several studies exist that use absorption line lengths to study the stellar populations of dwarf galaxies, studies of the Star Formation Histories in these

The environment of galaxies plays a key role in their evolution. The availability of large extragalactic surveys makes it possible to place a galaxy not only in its immediate environment, but also in its position within the large-scale structure of the universe. Within this context, we investigate how the local environment influences the star

To deepen our knowledge of the early history of the Milky Way, it is of particular interest to investigate the orbital and chemical properties of the most metal-poor stars, which are commonly associated with the oldest stars in our Universe. With the advent of astrometric (Gaia), spectroscopic (APOGEE, GALAH, LAMOST, Gaia-RVS), and photometric

Recent studies show that in Europe we are losing women's talent in some key disciplines for the future, particularly those directly related to astronomy. In order to get more girls and young women interested in the so-called STEM (Science, Technology, Engineering and Mathematics) fields, it is necessary to change the highly entrenched stereotypes

LIGHTS is an ultra-deep imaging survey that is 10 years ahead of the science to be done with the Vera Rubin Observatory. In this talk, I will update the current status of the survey with more than 25 nearby galaxies already observed with the LBT telescope in Arizona up to surface brightness ~31 mag/arcsec^2 in g and r bands. I will also discuss the

Open clusters are groups of coeval stars sharing properties such as distance and metallicity, and they are key to understanding stellar evolution. We shed light on the evolution of open clusters with a special focus on the universality of the luminosity function. We applied an upgraded version of the convergent point technique on about 50 open
