High-Ion Absorption in Seven GRB Host Galaxies at z=2-4: Evidence for both Circumburst Plasma and Outflowing Interstellar Gas
Andrew J. Fox, Cédric Ledoux, Paul M. Vreeswijk +2
(Abridged) We use VLT/UVES high-resolution optical spectroscopy of seven GRB afterglows at z_GRB>2 to investigate circumburst and interstellar plasma in the host galaxies. Our samp…
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-…
