Description
Using a large compilation of massive (stellar mass M≥10^{11} M_&sun;) earlytype galaxies (ETGs), we have probed, up to z˜1, whether the presence of satellites within a projected distance of 100 kpc of these objects depends on the size of the host massive galaxies. We do not find any evidence for satellites with a mass ratio down to 1:10 neither down to 1:100 to be preferentially located around compact or extended massive ellipticals. This suggests that, at least since z˜1, the merger activity in these objects is rather homogeneous across the whole population.

    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
