Are all short-hard gamma-ray bursts produced from mergers of compact stellar objects? (2009)

Virgili, Francisco J., Zhang, Bing, O'Brien, Paul, Troja, Eleonora

Abridged: The origin and progenitors of short-hard gamma-ray bursts remain a puzzle and a highly debated topic. The most popular model to interpret short-hard bursts is the merger of two compact...

Physical classification scheme of cosmological Gamma-ray bursts and their observational characteristics: on the nature of z=6.7 GRB 080913 and some short/hard GRBs (2009)

Zhang, Bing, Zhang, Bin-Bin, Virgili, Francisco J., Liang, En-Wei, Kann, D. Alexander, Wu, Xue-Feng, ...

(Abridged) The highest redshift (z=6.7) gamma-ray burst (GRB) 080913 recently detected by Swift is an intrinsically short, hard GRB. It would be recognized by BATSE as a short/hard GRB should it have...
