    Apostle-Auriga: effects of different subgrid models on the baryon cycle around Milky Way-mass galaxies
    Modern hydrodynamical simulations reproduce many properties of the real Universe. These simulations model various physical processes, but many of these are...

    Appearances can be deceiving: clear signs of accretion in the seemingly ordinary Sextans dSph
    We report the discovery of clear observational signs of past accretion/merger events in one of the Milky Way satellite galaxies, the Sextans dwarf spheroidal...

    Application of the Eddington inversion method to constrain the dark matter halo of galaxies using only observed surface brightness profiles
    Context. The halos of low-mass galaxies may allow us to constrain the nature of dark matter (DM), but the kinematic measurements needed to diagnose the required...

    Are dry mergers dry, moist or wet?
    We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum as dry merger remnants and ongoing dry mergers. Kinematics, stellar...

    Are early-type galaxies quenched by present-day environment?: A study of dwarfs in the Fornax Cluster
    Galaxies undergo numerous transformative processes throughout their lifetimes that ultimately lead to the expulsion of gas and the cessation of star-forming...

    Are Fossil Groups Early-forming Galaxy Systems?
    Using the Illustris cosmological simulation, we investigate the origin of fossil groups in the {M}200={10}13{--}{10}13.5 {M}⊙ {h}-1 mass regime. We examine the...

    Are luminous radio-loud active galactic nuclei triggered by galaxy interactions?
    We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2 Jy radio galaxies at intermediate redshifts (0.05...

    Are radio-loud Broad Absorption Line Quasars young sources?
    Studying Broad Absorption Line Quasars (BAL QSOs) is interesting because they probe the physics of the AGN environment, and because AGN outflows are important...

    Are the stellar winds in IC 1613 stronger than expected?
    In this poster we present the results of our analyses of three early massive stars in IC 1613, whose spectra have been observed with VIMOS and analyzed with...
