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

PublicationDwarf 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...

PublicationExploring 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...

PublicationObserving 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...

PublicationPhotometric 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...

PublicationPhysically 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...

PublicationThe 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...

PublicationThe 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...

PublicationUltramassive 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...
