GRS 1915+105

J. Greiner

I summarize recent near-infrared spectroscopy of the microquasar GRS 1915+105 with the ESO/VLT which allowed to (i) identify the donor and (ii) measure the orbital period and radia…

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 optical afterglow and host galaxy of GRB 000926

J. P. U. Fynbo, J. Gorosabel, P. Moller +7

In this paper we illustrate with the case of GRB 000926 how Gamma Ray Bursts (GRBs) can be used as cosmological lighthouses to identify and study star forming galaxies at high reds…

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 X-ray spectrum of LSI+61o303

J. Greiner, A. Rau

It had been proposed earlier that the hard X-ray and gamma-ray radiation of the Be/X-ray system LSI+61o303 could be due to inverse Compton scattering of optical photons from the Be…

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…
