    A Duality in the Origin of Bulges and Spheroidal Galaxies

    Studying the resolved stellar populations of the different structural components that build massive galaxies directly unveils their assembly history. We aim at...

    Dwarf Galaxies with Central Cores in Modified Newtonian Dynamics Gravity

    Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...

    Exploring the Galactic Warp through Asymmetries in the Kinematics of the Galactic Disk

    Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on...

    Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline

    We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six...

    Photometric Signature of Ultraharmonic Resonances in Barred Galaxies

    Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of "dark gaps," or regions of a...

    Physically Motivated Fit to Mass Surface Density Profiles Observed in Galaxies

    Polytropes have gained renewed interest because they account for several seemingly disconnected observational properties of galaxies. Here we study whether...

    The Black Hole Mass-Color Relations for Early- and Late-type Galaxies: Red and Blue Sequences

    The tight correlations between supermassive black hole (SMBH) mass (MBH) and the properties of the host galaxy have useful implications for our understanding of...

    The tilted old Galactic disc and the position of the Sun

    With the use of data from COBE, IRAS and the Two-micron Galactic Survey (TMGS), we examine the effect on star counts and surface brightness maps of the position...

    Ultramassive Black Holes in the Most Massive Galaxies: M<SUB>BH</SUB>-σ versus M<SUB>BH</SUB>-R<SUB>b</SUB>

    We investigate the nature of the relations between black hole (BH) mass (MBH) and the central velocity dispersion (σ) and, for core-Sérsic galaxies, the size of...
