The afterglow, redshift and extreme energetics of the gamma-ray burst of 23 January 1999
Article Abstract:
Long-lived emission or afterglow, has been detected from gamma-ray bursts at cosmological distances with redshifts, z, ranging from one to three. Optical and near-infrared observations of the afterglow of GRB990123 have determined a redshift of z>1.6 which is the brightest gamma-ray burst. The data may provide evidence of beamed radiation, rather than isotropic radiation.

Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB030329
Article Abstract:
The polarimetric observations of the afterglow of the gamma-ray burst GRB030329 is reported. The afterglow magnetic field has a small coherence length and is mostly random, probably generated by turbulence.
