The optical/near-IR spectral energy distribution of the GRB 000210 host galaxy
J. Gorosabel, L. Christensen, J. Hjorth +25
We report on UBVRIZJsHKs-band photometry of the dark GRB 000210 host galaxy. Fitting a grid of spectral templates to its Spectral Energy Distribution (SED), we derived a photometri…
Strategies for prompt searches for GRB afterglows: the discovery of the GRB 001011 optical/near-infrared counterpart using colour-colour selection
J. Gorosabel, J. U. Fynbo, J. Hjorth +25
We report the discovery of the optical and near-infrared counterparts to GRB 001011. The GRB 001011 error box determined by Beppo-SAX was simultaneously imaged in the near-infrared…
The bright optical afterglow of the long GRB 001007
J. M. Castro Cerón, A. J. Castro-Tirado, J. Gorosabel +35
We present optical follow up observations of the long GRB 001007 between 6.14 hours and ~468 days after the event. An unusually bright optical afterglow (OA) was seen to decline fo…
The extraordinarily bright optical afterglow of GRB 991208 and its host galaxy
A. J. Castro-Tirado, V. V. Sokolov, J. Gorosabel +50
Observations of the extraordinarily bright optical afterglow (OA) of GRB 991208 started 2.1 d after the event. The flux decay constant of the OA in the R-band is -2.30 +/- 0.07 up…
The afterglow of the short/intermediate-duration gamma-ray burst GRB 000301C: A jet at z=2.04
B. L. Jensen, J. U. Fynbo, J. Gorosabel +23
We present Ulysses and NEAR data from the detection of the short or intermediate duration (2 s) gamma-ray burst GRB000301C (2000 March 1.41 UT). The gamma-ray burst (GRB) was local…
Near-infrared detection and optical follow-up of the GRB990705 afterglow
N. Masetti
Optical and near-infrared observations of the GRB990705 error box were carried out with ESO telescopes at La Silla and Paranal in Chile and with the NOAO SPIREX 0.6-meter telescope…
