    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...

    Surface brightness fluctuation spectra to constrain stellar population properties
    We present a new set of surface brightness fluctuation (SBF) spectra computed with the E-MILES stellar population synthesis models. The model SBF spectra cover...

    Surface Brightness Fluctuations for constraining the chemical enrichment of massive galaxies
    Based on very deep photometry, Surface Brightness Fluctuations (SBF) have been traditionally used to determine galaxy distances. We have recently computed SBF...

    Surface brightness fluctuations to constrain secondary stellar populations: revealing very low-metallicity stars in massive galaxies
    The aim of this work is to explore the potential of surface brightness fluctuations (SBF) for studying composite stellar populations (CSP). To do so, we have...

    Surface density of extremely red objects with R - J ≥ 5
    We present the results of a wide-field survey for extremely red objects (EROs), based on J and R band imaging. The survey covers 2.89 deg2, consisting of 50...

    Surface density profiles of collisionless disc merger remnants
    We present a detailed surface density analysis of a large sample of simulated collisionless mergers of disc galaxies with bulges (mass ratios 1:1, 2:1, 3:1, 4:1...

    Surface-brightness fluctuations in stellar populations
    A new theoretical calibration of surface-brightness fluctuations (SBF) for single age, single metallicity stellar populations is presented for the optical and...

    Survival of molecular gas in a stellar feedback-driven outflow witnessed with the MUSE TIMER project and ALMA
    Stellar feedback plays a significant role in modulating star formation, redistributing metals, and shaping the baryonic and dark structure of galaxies - however...

    Survival of the Obscuring Torus in the Most Powerful Active Galactic Nuclei
    Dedicated searches generally find a decreasing fraction of obscured active galactic nuclei (AGN) with increasing AGN luminosity. This has often been interpreted...
