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 extraordinary SN 1997cy associated with GRB 970514 has been observed photometrically and spectroscopically for nearly 2.5 years as discussed by the authors, with the last available observations (600 days after the GRB) showing that the total time-integrated flux was equal to or larger than that expected from the complete thermalization of the gamma-rays produced by 2.3 Mo of 56Co.

TL;DR: In this paper, the authors compared the results of nucleosynthesis with the abundance patterns of intracluster matter, hot gases in M82, and extremely metal-poor stars in the Galactic halo.

TL;DR: In this article, the near-to mid-infrared (MIR) observation of supernova 2006jc at 200 days after the discovery using the Infrared Camera (IRC) on board AKARI is obtained for the first time and is found to be well interpreted in terms of the thermal emission from amorphous carbon of 800? 10 K with the mass of 6.9? 0.5? 10?5 M that was formed in the SN ejecta.

TL;DR: In this article, the near-to mid-infrared spectrum of SN2006jc is obtained for the first time and is found to be well interpreted in terms of the thermal emission from amorphous carbon of 800$\pm 10$K with the mass of $6.9\pm 0.5$\mu$m.
