Aims: Star-forming dwarfs are studied to elucidate the physical underpinnings of their fundamental plane. Processes controlling dynamics are evaluated...
Galaxias enanas: laboratorios privilegiados para el estudio de la materia oscura
La revista Nature Astronomy publica hoy, en su colección de publicaciones y reseñas dedicada a las galaxias enanas, un nuevo artículo escrito por Giuseppina...
GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
We present ∼115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We...
Globular Clusters as a Test for Gravity in the Weak Acceleration Regime
Non-baryonic Dark Matter (DM) appears in galaxies and other cosmic structures when and only when the acceleration of gravity, as computed considering only...
Globular clusters systems and their host dark matter halos
In the Λ-CDM galaxy formation paradigm, the star formation history of a galaxy is coupled to the total mass of its dark matter halo through processes like...
Gravitational lensing is a powerful astrophysical tool which allow us to studythe dark sector of the universe. Some of these applications include from thestudy...
We discuss the emission of gravitational radiation produced in encounters of dark matter galactic halos. To this aim we perform a number of numerical...
