TL;DR: In this paper, the authors reported the discovery of transient optical emission in the error box of the gamma-ray burst GRB980425, the light curve of which was very different from that of previous optical afterglows associated with Gamma-ray bursts.

TL;DR: In this article, the authors reported the discovery of an optical transient, in the BeppoSAX Wide Field Camera error box of GRB980425, which occurred within about a day of the gamma-ray burst.

TL;DR: The discovery of the unusual supernova SN1998bw, and its possible association with the γ-ray burst GRB 9804251,2,3, provide new insights into the explosion mechanism of very massive stars and the origin of some classes of gamma-ray bursts.

TL;DR: The discovery of the peculiar supernova (SN) 1998bw and its possible association with the gamma-ray burst (GRB) 980425$ 1,2,3} provides new clues to the understanding of the explosion mechanism of very massive stars and to the origin of some classes of gamma ray bursts.

TL;DR: The data, combined with radio and X-ray observations, suggest that XRF 060218 is an intrinsically weak and soft event, rather than a classical GRB observed off-axis, which extends the GRB–supernova connection to X-rays flashes and fainter supernovae, implying a common origin.
