The two-component jet of GRB 080413B
R. Filgas, T. Kruehler, J. Greiner +16
The quick and precise localization of GRBs by the Swift telescope allows the early evolution of the afterglow light curve to be captured by ground-based telescopes. With GROND meas…
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
T. Krühler, P. Schady, J. Greiner +18
We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for fi…
The nature of "dark" gamma-ray bursts
J. Greiner, T. Krühler, S. Klose +11
Context: Thirteen years after the discovery of the first afterglows, the nature of dark gamma-ray bursts (GRB) still eludes explanation: while each ng-duration GRB typically has an…
GRB 050502B optical afterglow: a jet break at high redshift
P. Afonso, J. Greiner, E. Pian +9
Aims: GRB 050502B is well known for the very bright flare displayed in its X-ray light curve. Despite extensive studies, however, the optical light curve has never been discussed a…
The Swift/Fermi GRB 080928 from 1 eV to 150 keV
A. Rossi, S. Schulze, S. Klose +28
We present the results of a comprehensive study of the gamma-ray burst 080928 and of its afterglow. GRB 080928 was a long burst detected by Swift/BAT and Fermi/GBM. It is one of th…
A very metal poor Damped Lyman-alpha system revealed through the most energetic GRB 090926A
Arne Rau, S. Savaglio, T. Krühler +9
We present VLT/FORS2 spectroscopy and GROND optical/near-IR photometry of the afterglow of the bright Fermi/LAT GRB 090926A. The spectrum shows prominent Lyman-alpha absorption wit…
