    • 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 ...
