    Formation of the first galaxies in the aftermath of the first supernovae
    We perform high-resolution cosmological hydrodynamic simulations to study the formation of the first galaxies that reach the masses of 10 8 - 9 h -1 M ⊙ at z =...

    Formation of ultra-diffuse galaxies in the field and in galaxy groups
    We study ultra-diffuse galaxies (UDGs) in zoom in cosmological simulations, seeking the origin of UDGs in the field versus galaxy groups. We find that while...

    Fornax 3D project: a two-dimensional view of the stellar initial mass function in the massive lenticular galaxy FCC 167
    The stellar initial mass function (IMF) regulates the baryonic cycle within galaxies, and is a key ingredient for translating observations into physical...

    Fornax 3D project: Assessing the diversity of IMF and stellar population maps within the Fornax Cluster
    The stellar initial mass function (IMF) is central to our interpretation of astronomical observables and to our understanding of most baryonic processes within...

    Fornax 3D project: Automated detection of planetary nebulae in the centres of early-type galaxies and first results
    Extragalactic planetary nebulae (PNe) are detectable through relatively strong nebulous [O III] emission and act as direct probes into the local stellar...

    Fornax3D project: Assembly history of massive early-type galaxies in the Fornax cluster from deep imaging and integral field spectroscopy
    This work is based on high-quality integral-field spectroscopic data obtained with the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT...

    Fornax3D project: Overall goals, galaxy sample, MUSE data analysis, and initial results
    The Fornax cluster provides a uniquely compact laboratory in which to study the detailed history of early-type galaxies and the role played by the environment...

    Fossil group origins - VI. Global X-ray scaling relations of fossil galaxy clusters
    We present the first pointed X-ray observations of 10 candidate fossil galaxy groups and clusters. With these Suzaku observations, we determine global...

    Fossil group origins. II. Unveiling the formation of the brightest group galaxies through their scaling relations
    Context. Fossil systems are galaxy associations dominated by a relatively isolated, bright elliptical galaxy, surrounded by a group of smaller galaxies lacking...
