Description
Besides the standard analysis based on mean properties, Surface Brightness Fluctuations (SBF) spectra provide an alternative way for studying stellar populations in galaxies. Metal-poor populations are predicted in galaxy formation models, but so far remain undetected beyond the Local Group. The SBF spectra have the potential to unveil these metal-poor components in galaxies dominated by old, metal-rich stars. We have computed SBF magnitudes and we propose fluctuation color diagrams to study composite populations in nearby elliptical galaxies.

    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
