Rise and fall of the X-ray flash 080330: an off-axis jet?
C. Guidorzi, C. Clemens, S. Kobayashi +31
X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with the peak energy of the time-integrated spectrum, Ep, below 30 keV, whereas classical GRBs have Ep of a few hundreds…
The redshift and afterglow of the extremely energetic gamma-ray burst GRB 080916C
J. Greiner, C. Clemens, T. Kruehler +22
The detection of GeV photons from gamma-ray bursts (GRBs) has important consequences for the interpretation and modelling of these most-energetic cosmological explosions. The full…
GROND - a 7-channel imager
J. Greiner, W. Bornemann, C. Clemens +19
We describe the construction of GROND, a 7-channel imager, primarily designed for rapid observations of gamma-ray burst afterglows. It allows simultaneous imaging in the Sloan g'r'…
The host galaxy of GRB 011121: Morphology and Spectral Energy Distribution
Aybuke Kupcu Yoldas, Mara Salvato, Jochen Greiner +3
(Abridged) We present a detailed study of the host galaxy of GRB 011121 (at z = 0.36) based on high-resolution imaging in 5 broad-band, optical and near-infrared filters with HST a…
Constraining the environment of GRB 990712 through emission line fluxes
Aybuke Kupcu Yoldas, Jochen Greiner, Rosalba Perna
The energy output in the gamma-ray burst (GRB) prompt emission and afterglow phase is expected to photoionize the surrounding medium out to large radii. Cooling of this gas produce…
Discovery of the Faint Near-IR Afterglow of GRB 030528
A. Rau, J. Greiner, S. Klose +7
We report on the discovery of the near-IR transient of the long-duration gamma-ray burst GRB 030528 and its underlying host galaxy. The near-IR transient was first observed in JHKs…
