    A tale of globular clusters formation and evolution. The case of the old, metal-poor globular cluster NGC4372
    I will talk about our current understanding of globular cluster (GC) formation and what we have yet to learn about them. I will particularly focus on the...

    Calar Alto Legacy Integral Field Area survey
    CALIFA is the largest IFS survey ever performed up to date. Recently started, it will observe ~600 galaxies in the Local Universe with PPAK at the 3.5m of the...

    Compact Galaxies and Super Massive Black Holes
    Most massive galaxies have supermassive black holes at their centres, and the masses of the black holes correlate with properties of the host-galaxy bulge...

    DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of Our Nearest Neighbor
    We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger-a galactic...

    Detection of Multiple Phase Space Overdensities of GSE Stars by Orbit Integration
    In N-body simulations, nearly radial mergers can form shell-like overdensities in the sky position and phase space (r - v r ) due to the combination of...

    Dynamics of galaxies and globular clusters unraveled with two-dimensional kinematics
    Two-dimensional stellar kinematics obtained with the integral-field spectrograph SAURON allow the classification of early-type galaxies into 'slow' and 'fast'...

    IAU G5 -- The GALAH survey: science goals and highlights to date
    The field of Galactic archaeology has been very active in recent years, with a major influx of data from the Gaia satellite and large spectroscopic surveys. The...

    IAU G5 talk: Stellar chemical compositions with 3D non-LTE models
    Spectroscopic analyses of stellar chemical compositions are model-dependent, and shortcomings in the models often limit the accuracy of the final results. For...

    IAU G5: "Extreme Precision Stellar Spectroscopy"
    The new generation of spectrometers designed for extreme precision radial velocities enable correspondingly precise stellar spectroscopy. It is now fruitful to...
