The general objective of this project is to exploit the potential of the Gaia mission, combined with the database built by our team in the last years, to bring substantial improvement in the determination of stellar distances and the early evolution of the LG galaxies. We will combine high resolution spectroscopy, optical and NIR photometric time

X-ray binaries (XRBs) are arguably the best sources for studying accretion and jets, because they traverse various accretion states with greatly differing jet strength, over timescales of the order of months, easily amenable to observation. However, despite the rapid increase in our phenomenological knowlege of jets, we still lack a fundamental

This project proposes a new approach to the studies of cultural astronomy (archaeoastronomy and ethnoastronomy) from a novel perspective, this time being the first occasion since this line of research began in Spain in which two institutions of recognized prestige and which are worldwide leaders in the field, the Institute of Astrophysics of the

The environment plays a key role in the formation and evolution of galaxies. Clusters of galaxies are the most massive and virialized structures known in the Universe and therefore are the ideal laboratories for the study of environmental processes in galaxies. It is not an easy task to discern, between the properties of galaxies, which have been

The Local Group (LG) offers us a chance to test the present scenario of galaxy formation in ways that are impossible elsewhere. It contains about 50 know galaxies, most of which are dwarfs so faint that they would not be detected beyond the LG. Hence, ourunderstanding of low-mass galaxy formation physics, strongly tied to models of galaxy feedback
