Mercator Array for Radial VELocities (MARVEL) is an ensemble of four 80-cm off the shelf telescopes feeding a single stabilised high-resolution (R>90 000) echelle spectrograph. The facility is currently under construction and will be located on La Palma (Canary Islands), next to the Mercator telescope. The facility is designed such that the four

The number of globular clusters plays a fundamental role in understanding the early stages of galaxy formation. We know that the GC population of normal galaxies correlates with the amount of dark matter in these objects. Extending this analysis to the number of globulars in very low surface brightness galaxies is therefore key to understanding the

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
