    • The ESO supernovae type Ia progenitor survey (SPY) : The radial velocities of 644 DA white dwarfs 

      Napiwotzki, R.; Karl, C. A.; Lisker, T.; Catalan, S.; Drechsel, H.; Heber, U.; Homeier, D.; Koester, D.; Leibundgut, B.; Marsh, T. R.; Moehler, S.; Nelemans, G.; Reimers, D.; Renzini, A.; Stroer, A.; Yungelson, L. (2019-07-27)
      Close double degenerate binaries are one of the favoured progenitor channels for type Ia supernovae, but it is unclear how many suitable systems there are in the Galaxy. We report results of a large radial velocity survey ...
    • 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 ...
