    Revealing the tidal scars of the Small Magellanic Cloud
    Due to their close proximity, the Large and Small Magellanic Clouds (LMC/SMC) provide natural laboratories for understanding how galaxies form and evolve. With...
  • Publication
    Reviewing the frequency and central depletion of ultra-diffuse galaxies in galaxy clusters from the KIWICS survey
    The number of ultra-diffuse galaxies (UDGs) in clusters is of significant importance to constrain models of their formation and evolution. Furthermore, their...

    Revised Primordial Helium Abundance Based on New Atomic Data
    We have derived a primordial helium abundance of Yp=0.2477+/-0.0029, based on new atomic physics computations of the recombination coefficients of He I and of...

    Revisiting the classics: is [Mg/Fe] a good proxy for galaxy formation time-scales?
    In the local Universe, massive early-type galaxies exhibit enhanced [Mg/Fe] ratios, which has been traditionally interpreted as the result of a rapid (τ ≲ 1 Gyr...

    Revisiting the formation history of the minor-axis dust lane galaxy NGC 1947
    In this paper, we present a detailed study of the peculiar early-type galaxy NGC 1947. The main goal of this work is to constrain the dynamical status and the...

    Revisiting the Hubble sequence in the SDSS DR7 spectroscopic sample: a publicly available Bayesian automated classification
    We present an automated morphological classification in 4 types (E, S0, Sab, Scd) of ~700 000 galaxies from the SDSS DR7 spectroscopic sample based on support...

    Revisiting the infrared spectra of active galactic nuclei with a new torus emission model
    We describe improved modelling of the emission by dust in a toroidal-like structure heated by a central illuminating source within active galactic nuclei (AGNs)...

    Revisiting the stellar velocity ellipsoid-Hubble-type relation: observations versus simulations
    The stellar velocity ellipsoid (SVE) in galaxies can provide important information on the processes that participate in the dynamical heating of their disc...

    Rise of the Titans: A Dusty, Hyper-luminous “870 μm Riser” Galaxy at z ∼ 6
    We report the detection of ADFS-27, a dusty, starbursting major merger at a redshift of z = 5.655, using the Atacama Large Millimeter/submillimeter Array (ALMA)...
