    Fossil group origins. XII. The large-scale environment around fossil systems
    Aims: We analyse the large-scale structure out to 100 Mpc around a sample of 16 confirmed fossil systems using spectroscopic information from the Sloan Digital...

    Fossil group origins. XIII. A paradigm shift: Fossil groups as isolated structures rather than relics of the ancient Universe
    Aims: In this work we study the large-scale structure around a sample of non-fossil systems and compare the results with earlier findings for a sample of...

    Fossil groups origins. I. RX J105453.3+552102 a very massive and relaxed system at z ~ 0.5
    Context. The most accepted scenario for the origin of fossil groups is that they are galaxy associations in which the merging rate was fast and efficient. These...

    From evolved stars to the formation and evolution of galaxies
    Due to observational constraints, our detailed knowledge of stellar populations, formation, and evolution of galaxies is limited to a few dozen galaxies located...
