O článku:

The origin of gamma-ray bursts (GRBs) is still a fascinating field of research nowadays. While we have been collecting more and more observationally constrained properties of GRB-physics, new theoretical results on the progenitor evolution (be it stellar or compact object) have also emerged. I review some of the most promising progenitor theories for forming a short-duration GRB. A special emphasis is put on the hypothetical case of forming a short-duration GRB through the double black hole merger scenario — in which case we may expect to observe a gravitational wave emission too. The chemically homogeneous channel for forming a black hole binary is discussed, and the stellar progenitors (so called TWUIN stars) are introduced. The birth place of these short-duration GRBs with a gravitational wave counterpart may be low-metallicity, starforming dwarf galaxies.
