Ackermann M, Ajello M, Asano K, Atwood W, Axelsson M, Baldini L, et al.
Science . 2013 Nov; 343(6166):42-7. PMID: 24263133
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature of these unique astrophysical...

Preece R, Burgess J, von Kienlin A, Bhat P, Briggs M, Byrne D, et al.
Science . 2013 Nov; 343(6166):51-4. PMID: 24263132
Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 seconds is possibly the brightest well-isolated pulse observed to date. A...
