    • Probing gamma-ray burst environments with time variability: ULTRASPEC fast imaging of GRB 080210 

      De Cia, A.; Jakobsson, P.; Bjornsson, G.; Vreeswijk, P. M.; Dhillon, V. S.; Marsh, T. R.; Chapman, R.; Fynbo, J. P. U.; Ledoux, C.; Littlefair, S. P.; Malesani, D.; Schulze, S.; Smette, A.; Zafar, T.; Gudmundsson, E. H. (2011-04)
      We present high time resolution (1.09 s) photometry of GRB 080210 obtained with ULTRASPEC mounted on the ESO/3.6-m telescope, starting 68.22 min after the burst and lasting for 26.45 min. The light curve is smooth on both ...

    • The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1 

      Littlefair, S.P.; Casewell, S.L.; Parsons, S.G.; Dhillon, V. S.; Marsh, T.R.; Gansicke, B.T.; Bloemen, S.; Catalan, Silvia; Irawati, P.; Hardy, L.K.; Mcallister, M.; Bours, M.C.P.; Richichi, A.; Burleigh, M.R.; Burningham, B.; Breedt, E.; Kerry, P. (2014-12-01)
      We present high time resolution SDSS-g′ and SDSS-z′ light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near-infrared (NIR) JHKs photometry. Our observations ...
