    Aims.We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 h and ~1.15 yr after the event. It is the most intense gamma-ray burst (~10-4 erg cm-2) detected by HETE-2, ...

    Castro-Tirado, A. J; Jelínek, M; Pandey, S. B; McBreen, S; de Jong, J; Sahu, D. K; Ferrero, P; Caballero, J. A; Gorosabel, J; Kann, D. A; Klose, S; de Ugarte Postigo, A; Anupama, G. C; Gry, C; Guziy, S; Srividya, S; Valdivielso, L; Vanniarajan, S; Henden, A. A (EDP Sciences, 2006-12)
    We present multiwavelength observations of the gamma-ray burst GRB 051028 detected by HETE-2 in order to derive its afterglow emission parameters and to determine the reason for its optical faintness when compared to other ...
  • The latest two GRB detected by Hete-2: GRB 051022 and GRB 051028 
    Castro-Tirado, A. J; McBreen, S; Jelínek, M; Pandey, S. B; Bremer, M; de Ugarte Postigo, A; Gorosabel, J; Guziy, S; Bihain, G; Caballero, J. A; Ferrero, P; de Jong, J; Misra, K; Sahu, D. K (American Institute of Physics, 2006-05)
    We present multiwavelength observations of the latest two GRB detected by Hete-2 in 2005. For GRB 051022, no optical/nIR afterglow has been detected, in spite of the strong gamma-ray emission and the reported X-ray afterglow ...
  • Multi-wavelength afterglow observations of the high redshift GRB 050730 
    Pandey, S. B; Castro-Tirado, A. J; McBreen, S; Pérez-Ramírez, M. D; Bremer, M; Guerrero, M. A; Sota, A; Cobb, B.

K; Sharma, S; Bogdanov, O; Combi, J. A (EDP Sciences, 2006-12)
    Context.GRB 050730 is a long duration high-redshift burst (z=3.967) that was discovered by Swift. The afterglow shows variability and was well monitored over a wide wavelength range. We present comprehensive temporal and ...

E; Sergeev, A; Sonbas, E; Sota, A; Tello, J. C; Yamaoka, K; Yost, S. A; Yuan, F (IOP Publishing, 2012-06-01)
    We present a comprehensive analysis of a bright, long-duration (T /sub90/ ~ 257 s) GRB 110205A at redshift z = 2.22. The optical prompt emission was detected by Swift/UVOT, ROTSE-IIIb, and BOOTES telescopes when the gamma-ray ...
