Description
We present wide-field ground based photometry for the Galactic globular cluster M92. Data were collected in the SDSS bands (u',g',r',i',z') with the MegaCam@CFHT. We confirm the occurrence of cluster stars beyond the tidal radius. Moreover, we find that the ratio between the Horizontal Branch (HB) stars and Main Sequence (MS) stars across the turn-off region clearly decreases by a factor of two when moving from the centre to the outermost regions of the cluster.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
