The bright optical/NIR afterglow of the faint GRB 080710 - Evidence for a jet viewed off axis
T. Krühler, J. Greiner, P. Afonso +14
We investigate the optical/near-infrared light curve of the afterglow of GRB 080710 in the context of rising afterglows. Optical and near-infrared photometry was performed using th…
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…
Correlated optical and X-ray flares in the afterglow of XRF 071031
T. Krühler, J. Greiner, S. McBreen +8
We present a densely sampled early light curve of the optical/near-infrared (NIR) afterglow of the X-Ray Flash (XRF) 071031 at z=2.692. Simultaneous and continuous observations in…
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…
A candidate tidal disruption event in the Galaxy cluster Abell 3571
N. Cappelluti, M. Ajello, P. Rebusco +8
Tidal disruption events are possible sources of temporary nuclear activity in galactic nuclei and can be considered as good indicators of the existence of super massive black holes…
