    • Are short y-ray bursts collimated GRB 050709, a flare but no break 

      Watson, D.; Hjorth, J.; Jakobsson, P.; Xu, D.; Fynbo, J.; Sollerman, J.; Thone, C.C.; Pedersen, K. (2006)
      Context. From the small sample of afterglow lightcurves of short duration γ-ray bursts (GRBs), the decays are rapid, roughly following a power-law in time. It has been assumed that the afterglow emission in short GRBs is ...
    • 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 ...
    • An extremely luminous panchromatic outburst from the nucleus of a distant galaxy 

      Levan, Andrew; Tanvir, Nial; Cenko, S.B.; Perley, D.A.; Wiersema, K.; Bloom, J.S.; Fruchter, A.S.; Postigo, A.; O'Brien, O.T.; Butler, N.R.; van der Horst, A.J.; Leloudas, G.; Morgan, A.N.; Misra, K.; Bower, G.C.; Farihi, J.; Tunnicliffe, R.L.; Modjaz, M.; Silverman, J.M.; Hjorth, J.; Thone, C.C.; Cucchiara, A.; Ceron, J.M.C.; Castro-Tirado, A.J.; Arnold, J.A.; Bremer, M.; Brodie, J.P.; Carroll, T.; Cooper, M.C.; Curran, P.; Cutri, R.M.; Ehle, J.; Forbes, D.; Fynbo, J.; Gorosabel, J.; Graham, J.; Hoffman, D.I.; Guziy, S.; Jakobsson, Pall; Kamble, A.P.; Kerr, T.H.; Kasliwal, M.M.; Kouveliotou, C.; Kocevski, D.; Law, N.M.; Nugent, P.; Ofek, E.O.; Poznanski, D.; Quimby, R.M.; Rol, E.; Romanowsky, A.J.; Sanchez-Ramirez, R.; Schulze, S.; Singh, N.; Van Spaandonk, Lieke; Starling, R.L.; Strom, R.G.; Tello, J.C.; Vaduvescu, O.; Wheatley, P.J.; Wijers, R.A.M.J.; Winters, J.M.; Xu, D. (2011)
      Variable x-ray and gamma-ray emission is characteristic of the most extreme physical processes in the universe. We present multiwavelength observations of a unique gamma-ray-selected transient detected by the Swift satellite, ...
