INTEGRAL monitoring of unusually long X-ray bursts
J. Chenevez, M. Falanga, E. Kuulkers +3
X-ray bursts are thermonuclear explosions on the surface of accreting neutron stars in low mass X-ray binaries. As most of the known X-ray bursters are frequently observed by INTEG…
Serpens X-1 observed by INTEGRAL
N. Masetti, L. Foschini, E. Palazzi +13
Here we report results of an INTEGRAL-AO1 observation of the X-ray burst and atoll source Ser X-1 performed in May 2003. The object was observed for a total on-source time of 400 k…
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…
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…
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…
A multi-colour study of the dark GRB 000210 host galaxy and its environment
J. Gorosabel, L. Christensen, J. Hjorth +25
We present UBVRIZJsHKs broad band photometry of the host galaxy of the dark gamma-ray burst (GRB) of February 10, 2000. These observations represent the most exhaustive photometry…
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…
Follow-up observations from observatories based in Spain
Javier Gorosabel, Alberto J. Castro-Tirado, Jochen Greiner +4
We present a review of the follow-up observations carried out from observatories located in Spain; Calar-Alto, Izanha and Roque de Los Muchachos. It summarizes the observations car…
Optical observations of the dark Gamma-Ray Burst GRB 000210
Javier Gorosabel, Jens Hjorth, Holger Pedersen +11
We report on optical observations on GRB 000210 obtained with the 2.56-m Nordic Optical Telescope and the 1.54-m Danish Telescope starting 12.4 hours after the gamma-ray event. The…
Ballerina - Pirouettes in Search of Gamma Bursts
S. Brandt, N. Lund, H. Pedersen +1
The cosmological origin of gamma ray bursts has now been established with reasonable certainty. Many more bursts will need to be studied to establish the typical distance scale, an…
Optical and near-infrared observations of the GRB 970616 error box
J. Gorosabel, A. J. Castro-Tirado, H. Pedersen +7
We report on near-infrared and optical observations of the GRB 970616 error box and of the X-ray sources discovered by ASCA and ROSAT in the region. No optical transient was found…
An optical study of the GRB 970111 field beginning 19 hours after the Gamma-Ray Burst
J. Gorosabel, A. J. Castro-Tirado, C. Wolf +13
We present the results of the monitoring of the GRB 970111 field that started 19 hours after the event. This observation represents the fastest ground-based follow-up performed for…
A BATSE-based search for repeaters in the sample of gamma-ray bursts detected by the WATCH experiment
J. Gorosabel, A. J. Castro-Tirado, S. Brandt +1
This study is the first known attempt to search for gamma-ray burst repeaters combining data from gamma-ray experiments flying on board different satellites and making use of infor…
