    • Early spectroscopic identification of SN 2008D 

      Malesani, D.; Fynbo, J.; Hjorth, J.; Leloudas, G.; Sollerman, J.; Stritzinger, M.; Vreeswijk, P.M.; Watson, D.; Gorosabel, J.; Michalowski, M.; Thone, C.C.; Augusteijn, T.; Bersier, D.; Jakobsson, P.; Jaunsen, A.O.; Ledoux, C.; Levan, A.; Milvang-Jensen, B.; Rol, E.; Tanvir, N.; Wiersema, K.; Xu, D. (2009)
      SN 2008D was discovered while following up an unusually bright X-ray transient (XT) in the nearby spiral galaxy NGC 2770. We present early optical spectra (obtained 1.75 days after the XT) which allowed the first identification ...

    • 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 ...
