  • Tracing the stellar component of low surface brightness Milky Way dwarf galaxies to their outskirts 

    Cicuéndez, L; Battaglia, G; Irwin, Michael John; Bermejo-Climent, JR; McMonigal, B; Bate, Nicholas Frazer; Lewis, GF et al. (2018-01-01)
  • Binary stars in the Galactic thick disc 

    Izzard, Robert George; Preece, Holly; Jofre, Paula; Halabi, Ghina M; Masseron, Thomas; Tout, Christopher Adam (2018-01)
    The combination of asteroseismologically-measured masses with abundances from detailed analyses of stellar atmospheres challenges our fundamental knowledge of stars and our ability to model them. Ancient red-giant stars ...
  • Gravitationally lensed quasars in Gaia: I. Resolving small-separation lenses 

    Lemon, Cameron A; Auger, Matthew W; McMahon, Richard Gerard; Koposov, Sergey E (Oxford University Press, 2017-12)
    Gaia’s exceptional resolution (FWHM ~ 0.1 arcsec) allows identification and cataloguing of the multiple images of gravitationally lensed quasars. We investigate a sample of 49 known lensed quasars in the Sloan Digital Sky ...
  • X-ray lags in PDS 456 revealed by Suzaku observations 

    Chiang, Chia-Ying; Cackett, EM; Zoghbi, A; Fabian, Andrew Christopher; Kara, E; Parker, ML; Reynolds, Christopher Stephen et al. (Oxford University Press, 2017-12-01)
    X-ray reverberation lags from the vicinity of supermassive black holes have been detected in almost 30 active galactic nuclei (AGNs). The soft lag, which is the time delay between the hard and soft X-ray light curves, is ...
