    Impacts of Bar-driven Shear and Shocks on Star Formation
    Bars drive gas inflow. As the gas flows inward, shocks and shear occur along the bar dust lanes. Such shocks and shear can affect the star formation (SF) and...

    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 (M BH) and the properties of the host galaxy have useful implications for our understanding...

    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 (M BH) and the central velocity dispersion (σ) and, for core-Sérsic galaxies, the size...

    Un estudio revela que la forma de la Galaxia Remolino se ha moldeado por el paso repetido de una galaxia satélite
    Una investigación internacional, en la que participa el Instituto de Astrofísica de Canarias (IAC), revela que la galaxia satélite NGC5195 ha pasado dos veces...
