TL;DR: In this article, the authors reported on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its optical/NIR afterglow and the recognition of its high-z nature via the detection of a spectral break between the i' and z' bands.
Journal ArticleDOI

TL;DR: In this paper, the authors reported the discovery of the afterglow and subsequent redshift determination of GRB 080916C, the first GRB detected by the Fermi Gamma-Ray Space Telescope with high significance detection of photons at energies > 0.1 GeV.
Journal ArticleDOI
Optical and near-infrared follow-up observations of four Fermi/LAT GRBs: redshifts, afterglows, energetics, and host galaxies

TL;DR: In this article, the afterglows of four gamma-ray bursts with high energy emission detected by Fermi/LAT were obtained in the optical/near-infrared bands with GROND mounted at the MPG/ESO 2.2 m telescope.
Journal ArticleDOI
Supersolar metal abundances in two galaxies at z ∼ 3.57 revealed by the GRB 090323 afterglow spectrum

TL;DR: In this article, high metallicity measured in two absorption systems at high redshift, detected in the Very Large Telescope spectrum of the afterglow of the gamma-ray burst GRB090323.
Journal ArticleDOI

TL;DR: In this paper, the authors present observations and analysis of the broad-band afterglow of Swift GRB 071025 using optical and infrared (RIYJHK) photometry and derive a photometric redshift of 4.4 < z < 5.2.
