    A KMOS survey of the nuclear disk of the Milky Way. I. Survey design and metallicities
    Context. In the central few degrees of the bulge of the Milky Way there is a flattened structure of gas, dust, and stars, known as the central molecular zone...

    A Large Ground-based Observing Campaign of the Disintegrating Planet K2-22b
    We present 45 ground-based photometric observations of the K2-22 system collected between 2016 December and 2017 May, which we use to investigate the evolution...

    A large sub-Neptune transiting the thick-disk M4 V TOI-2406
    Context. Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the...

    A multi-planetary system orbiting the early-M dwarf TOI-1238
    Context. The number of super-Earth and Earth-mass planet discoveries has increased significantly in the last two decades thanks to the Doppler radial velocity...

    A multi-wavelength analysis of M 81: insight on the nature of Arp's loop
    Context. The optical ring-like structure detected by Arp (1965) around M 81 (commonly referenced as “Arp's loop”) represents one of the most spectacular...

    A multifrequency maximum-entropy joint analysis of COBE and Tenerife data
    We use data from the Tenerife 10-, 15- and 33-GHz beam-switching experiments along with the COBE 53- and 90-GHz data to separate the cosmic microwave background...
  • Publication
    A multiwavelength analysis of a collection of short-duration GRBs observed between 2012 and 2015
    We investigate the prompt emission and the afterglow properties of short-duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015...
  • Publication
    A near-infrared survey for new low-mass members in α Per
    We present a near-infrared (K'-band) survey of 0.7 square degree area in the α Persei open cluster (age = 90 Myr, distance = 182 pc) carried out with the Omega...

    A New Approach to the Solar Oxygen Abundance Problem
    In this work we present new data that sets strong constraints on the solar oxygen abundance. Our approach, based on the analysis of spectropolarimetric...
