GRB 030227: the first multiwavelength afterglow of an INTEGRAL GRB
A. J. Castro-Tirado, J. Gorosabel, S. Guziy +39
We present multiwavelength observations of a gamma-ray burst detected by INTEGRAL (GRB 030227) between 5.3 hours and ~1.7 days after the event. Here we report the discovery of a di…
First INTEGRAL observations of GRS 1915+105
D. C. Hannikainen, O. Vilhu, J. Rodriguez +20
We present data from the first of six monitoring Open Time observations of GRS 1915+105 undertaken with the orbiting INTEGRAL satellite. The source was clearly detected with all th…
The blue host galaxy of the red GRB 000418
J. Gorosabel, S. Klose, L. Christensen +25
We report on multi-band (UBVRIZJsKs) observations of the host galaxy of the April 18, 2000 gamma-ray burst. The Spectral Energy Distribution (SED) is analysed by fitting empirical…
Variable polarization in the optical afterglow of GRB 021004
E. Rol, R. A. M. J. Wijers, J. P. U. Fynbo +19
We present polarimetric observations of the afterglow of gamma-ray burst (GRB) 021004, obtained with the Nordic Optical Telescope (NOT) and the Very Large Telescope (VLT) between 8…
INTEGRAL and XMM-Newton observations of the weak GRB 030227
S. Mereghetti, D. Gotz, A. Tiengo +16
We present INTEGRAL and XMM-Newton observations of the prompt gamma-ray emission and the X-ray afterglow of GRB030227, the first GRB for which the quick localization obtained with…
Optical afterglow of the not so dark GRB 021211
S. B. Pandey, G. C. Anupama, R. Sagar +5
We determine Johnson and Cousins photometric CCD magnitudes for the afterglow of GRB 021211 during the first night after the GRB trigger. The afterglow was very faint a…
