    Unprecedented study of the broadband emission of Mrk 421 during flaring activity in March 2010
    Context. Because of its proximity, Mrk 421 is one of the best sources on which to study the nature of BL Lac objects. Its proximity allows us to characterize...

    Unravelling the mass spectrum of destroyed dwarf galaxies with the metallicity distribution function
    Accreted stellar populations are comprised of the remnants of destroyed galaxies, and often dominate the 'stellar haloes' of galaxies such as the Milky Way (MW)...

    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...
