We study the behaviour of the dynamical and stellar mass inside the effective radius of early-type galaxies (ETGs) as a function of environment considering Newtonian dynamics, different surface-brightness profiles, different initial mass functions (IMF), and different redshift ranges. We use several samples of ETGs - ranging from 19 000 to 98 000

The MASCARA/bRing network consists of four separate observatories, located in La Palma, La Silla, Sutherland, and Siding Springs, and searches for exoplanet transits around bright stars. The three southern hemisphere stations allow for near continuous observations between the declination range of -30 to -90 degrees. These stations are sensitive to

The Magellanic Clouds (MCs) are the most massive gas-bearing systems falling into the Galaxy at the present epoch. They show clear signs of interaction, manifested in particular by the Magellanic Stream, a spectacular gaseous wake that trails from the MCs extending more than 150° across the sky. Ahead of the MCs is the `Leading Arm' usually

The present work aims to characterize some of the possible sources of near-Earth asteroids Bennu and Ryugu, targets of the sample-recovery missions OSIRIS-REx and Hayabusa2, respectively. The characterization of the sources of these NEAs will enhance the scientific results of the missions, helping to understand how these objects reach their current

Context. In the era of large high-resolution spectroscopic surveys such as Gaia-ESO and APOGEE, high-quality spectra can contribute to our understanding of the Galactic chemical evolution by providing abundances of elements that belong to the different nucleosynthesis channels, and also by providing constraints to one of the most elusive

From CCD observations carried out with different telescopes, we present short-term photometric measurements of the large trans-Neptunian object Varuna in 10 epochs, spanning around 19 years. We observe that the amplitude of the rotational light curve has changed considerably during this period of time from 0.41 to 0.55 mag. In order to explain this
