IFU observations of the GRB 980425/SN 1998bw host galaxy: emission line ratios in GRB regions
L. Christensen, P. M. Vreeswijk, J. Sollerman +3
The collapsar model predicts that the progenitors of Gamma-ray Bursts (GRBs) are metal poor in Fe group elements. The existence of low metallicity stellar populations could manifes…
GRB 070306: A Highly Extinguished Afterglow
A. O. Jaunsen, E. Rol, D. J. Watson +12
We report on the highly extinguished afterglow of GRB 070306 and the properties of the host galaxy. An optical afterglow was not detected at the location of the burst, but in near-…
GRB 060206 and the quandary of achromatic breaks in afterglow light curves
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +20
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX era. We present our multi-wavelength analysis of GRB…
Spectroscopy and multiband photometry of the afterglow of intermediate duration gamma-ray burst 040924 and its host galaxy
K. Wiersema, A. J. van der Horst, D. A. Kann +19
We present optical photometry and spectroscopy of the afterglow and host galaxy of gamma-ray burst 040924. This GRB had a rather short duration of T90 ~2.4s, and a well sampled opt…
On the nature of the short duration GRB 050906
A. J. Levan, N. R. Tanvir, P. Jakobsson +12
We present deep optical and infrared observations of the short duration GRB 050906. Although no X-ray or optical/IR afterglow was discovered to deep limits, the error circle of the…
Spatially resolved properties of the GRB 060505 host: implications for the nature of the progenitor
Christina C. Thoene, Johan P. U. Fynbo, Goeran Oestlin +12
GRB 060505 was the first well-observed nearby possible long-duration GRB that had no associated supernova. Here we present spatially resolved spectra of the host galaxy of GRB 0605…
