    Searching for Tidal Remnants in the Milky Way: Photometric Survey of Globular Clusters
    The picture of building the Milky Way halo from the merger of protogalactic fragments is considered the local manifestation of the hierarchical galaxy formation...

    Secondary halo bias through cosmic time. I. Scaling relations and the connection with the cosmic web
    Context. The spatial distribution of dark matter halos carries cosmological and astrophysical information. Cosmological information can be considered to be...

    Secondary Infall in the Seyfert’s Sextet: A Plausible Way Out of the Short Crossing Time Paradox
    We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly available data to investigate the star formation histories of galaxies in the...

    Secular Evolution and a Non-evolving Black-hole-to-galaxy Mass Ratio in the Last 7 Gyr
    We present new constraints on the ratio of black hole (BH) mass to total galaxy stellar mass at 0.3 z 0.9 for a sample of 32 type-1 active galactic nuclei...

    Secular- and merger-built bulges in barred galaxies
    Context. Historically, galaxy bulges were thought to be single-component objects at the center of galaxies. However, this picture is now questioned since...

    Seeking footprints of the primeval Universe in dwarf galaxies
    We present the star formation histories (SFHs) of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix, as a function of galactocentric radius. Our...

    Self-interacting dark matter and the delay of supermassive black hole growth
    Using cosmological hydrodynamic simulations with physically motivated models of supermassive black hole (SMBH) formation and growth, we compare the assembly of...

    Separation between RR Lyrae and type II Cepheids and their importance for a distance determination: the case of omega Cen
    The separation between RR Lyrae (RRLs) and type II Cepheid (T2Cs) variables based on their period is debated. Both types of variable stars are distance...
