    Supermassive black hole wake or bulgeless edge-on galaxy?. II. Order-of-magnitude analysis of the two physical scenarios
    Context. A recently discovered thin long object aligned with a nearby galaxy could be the stellar wake induced by the passage of a supermassive black hole (SMBH...

    Supermassive black holes and dark matter halos
    Recently a tight correlation between the bulge velocity dispersion and the galaxy circular velocity has been found for a sample of spiral galaxies (Ferrarese...

    Supermassive black holes from OASIS and SAURON integral-field kinematics
    Supermassive black holes are a key element in our understanding of how galaxies form. Most of the progress in this very active field of research is based on...

    Supermassive black holes in the EAGLE Universe. Revealing the observables of their growth
    We investigate the evolution of supermassive black holes in the `Evolution and Assembly of GaLaxies and their Environments' (EAGLE) cosmological hydrodynamic...

    Supernovae and Their Expanding Blast Waves during the Early Evolution of Galactic Globular Clusters
    Our arguments deal with the early evolution of Galactic globular clusters and show why only a few of the supernovae (SNe) products were retained within globular...

    Supershells as probe particles for the study of the galactic spin orientation
    Here we describe a method that can be used to derive, with a high degree of confidence, the direction of the rotation axis of a galaxy. The method is based on...

    Supersonic Line Broadening within Young and Massive Super Star Clusters
    The origin of supersonic infrared and radio recombination nebular lines often detected in young and massive superstar clusters is discussed. We suggest that...

    Support for the Gravitational Lens Interpretation of SBS 0909+532
    The system SBS 0909+532A, B is a double consisting of a quasar and a fainter component that was, until now, spectroscopically unresolved. Spectra taken in good...

    Surface Brightness and Stellar Populations at the Outer Edge of the Large Magellanic Cloud: No Stellar Halo Yet
    We present a high-quality color-magnitude diagram (CMD) for a 36'×36' field located 8° (~=7 kpc) from the Large Magellanic Cloud (LMC) center, as well as a...
