    Unravelling the origins of S0 galaxies using maximum likelihood analysis of planetary nebulae kinematics
    To investigate the origins of S0 galaxies, we present a new method of analysing their stellar kinematics from discrete tracers such as planetary nebulae. This...

    Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
    Here, we report an ensemble study of 214 A- and F-type stars observed by Kepler, exhibiting the so-called hump and spike periodic signal, explained by Rossby...

    Unusual high-frequency oscillations in the Kepler δ Scuti star KIC 4840675
    We show that the star KIC 4840675 observed by Kepler is composed of three stars with a rapidly rotating A-type star and two solar-type fainter companions. The A...

    Unveiling the (in)consistencies among the galaxy stellar mass function, star formation histories, satellite abundances, and intracluster light from a semi-empirical perspective
    In a hierarchical, dark matter-dominated Universe, stellar mass functions (SMFs), galaxy merger rates, star formation histories (SFHs), satellite abundances...

    Unveiling the 100 pc scale nuclear radio structure of NGC 6217 with e-MERLIN and the VLA
    We present high-sensitivity 1.51 GHz e-MERLIN (e-Multi-Element Radio-Linked Interferometer Network) radio images of the nearby galaxy NGC 6217. We resolve the...

    Unveiling the monster heart: unbeamed properties of blazar 4C 71.07
    4C 71.07 is a high-redshift blazar whose optical radiation is dominated by quasar-like nuclear emission. We here present the results of a spectroscopic...
  • Publication
    Unveiling the purely young star formation history of the SMC's northeastern shell from colour-magnitude diagram fitting
    We obtain a quantitative star formation history (SFH) of a shell-like structure ('shell') located in the northeastern part of the Small Magellanic Cloud (SMC)...

    Unveiling the redback nature of the low-mass X-ray binary XSS J1227.0-4859 through optical observations
    The peculiar low-mass X-ray binary XSS J12270-4859, associated with the Fermi/LAT source 2FGL J1227.7-4853, was in an X-ray, gamma-ray and optical low...

    Upholding the unified model for active galactic nuclei: VLT/FORS2 spectropolarimetry of Seyfert 2 galaxies
    The origin of the unification model for active galactic nuclei (AGN) was the detection of broad hydrogen recombination lines in the optical polarized spectrum...
