TL;DR: In this article, the authors present multicolor optical and two-frequency radio observations of the bright BeppoSAX event GRB 990510 and derive a jet opening angle of θ_0 = 0.08(n/1 cm^(-3))^(1/8), reducing the isotropic gamma-ray energy release by a factor of ~300.

TL;DR: It is determined that the TGF emission above 10 MeV has a significant power-law spectral component reaching energies up to 100 MeV, and these results challenge TGF theoretical models based on runaway electron acceleration.

TL;DR: In this paper, the gamma-ray emission above 100 MeV from IC 443 as obtained by the AGILE satellite was studied. And it was shown that electrons cannot be the main emitters of gamma-rays in the range 0.1-10 GeV at the site of the strongest SNR shock.
