    • Absorption systems in the spectrum of GRB 021004 

      Moller, P.; Fynbo, J.; Hjorth, J.; Thomsen, B.; Egholm, M.P.; Andersen, M.I.; Gorosabel, J.; Holland, S.T.; Jakobsson, P.; Jensen, B.L.; Pedersen, H.; Pedersen, K.; Weidinger, M. (2002)
      We report on a 3600 s spectrum of GRB 021004 obtained with the Nordic Optical Telecope on La Palma 10.71 hours after the burst. We identify absorption lines from five systems at redshifts 1.3806, 1.6039, 2.2983, 2.3230, ...

    • The afterglow and the host galaxy of GRB 011211 

      Jakobsson, P.; Hjorth, J.; Fynbo, J.; Gorosabel, J.; Pedersen, K.; Burud, I.; Levan, A.; Kouveliotou, C.; Tanvir, N.; Fruchter, A.S.; Rhoads, J.E.; Grav, T.; Hansen, M.W.; Michelsen, R.; Andersen, M.I.; Jensen, B.L.; Pedersen, K.; Thomsen, B.; Weidinger, M.; Causik, R.; Pandey, S.B. (2003)
      We present optical, near-infrared, and X-ray observations of the optical afterglow (OA) of the X-ray rich, longduration gamma-ray burst GRB 011211. Hubble Space Telescope (HST) data obtained 14, 26, 32, and 59 days after ...
