Description
We are presenting new empirical fitting functions for the Lick/IDS line-strength indices as measured in MILES (Medium-resolution INT Library of Empirical Spectra). Following previous work in the field, these functions describe the empirical behaviour of the line-strength indices with the atmospheric stellar parameters (T eff, logg, [Fe/H]). In order to derive the fitting functions we have devised a new procedure which, being fully automatic, provides a better description of the line-strength index variations in the stellar parameter space.

    Unveiling galaxy protoclusters in the era of Euclid
    How large-scale structures formed in the early universe is a key cosmological question with few answers from empirical evidence. Unveiling galaxy clusters and their high-z progenitors (i.e., protoclusters) is essential to picture galaxy evolution drawn by the hierarchical formation scenario. However, unveiling these early structures at high

    Accretion and winds in neutron star low-mass X-ray binaries
    In recent decades, observations of the X-ray and radio continuum have been instrumental in studying the coupling between accretion and ejection processes in low-mass X-ray binaries (LMXBs), with emphasis on systems harbouring black hole accretors. However, we have only recently begun to systematically study the evolution of their X-ray, optical and

    Constraining in-situ vs. ex-situ stellar mass in nearby galaxies with simulation-based inference
    Understanding the complexities of galaxy evolution and the role of mergers therein remains a fundamental challenge in astrophysics. Since galaxies can only be observed at a single point in cosmic time, tracing their merging history and its impact on a galaxy's mass assembly is heavily dependent on models or cosmological simulations. However, while
