Gravitational wave: gamma-ray burst connections
After 35 years of experimental research, we are rapidly approaching the point at which gravitational waves (GWs) from astrophysical sources may be directly detected by the long-baseline detectors LIGO (USA), GEO 600 (Germany/UK), VIRGO (Italy/France) and TAMA 300 (Japan), which are now in or coming into operation. A promising source of GWs is the coalescence of compact binary systems, events wh...

متن کاملEnergetics and Beaming of Gamma Ray Burst Triggers
A wide range of mechanisms have been proposed to supply the energy for gamma-ray bursts (GRB) at cosmological distances. It is a common misconception that some of these, notably NS-NS mergers, cannot meet the energy requirements suggested by recent observations. We show here that GRB energies, even at the most distant redshifts detected, are compatible with current binary merger or collapse sce...
متن کاملAfterglows as Diagnostics of Gamma Ray Burst Beaming
If gamma ray bursts are highly collimated, radiating into only a small fraction of the sky, the energy requirements of each event may be reduced by several (up to 4–6) orders of magnitude, and the event rate increased correspondingly. The large Lorentz factors (Γ ∼ 100) inferred from GRB spectra imply relativistic beaming of the gamma rays into an angle ∼ 1/Γ. We are at present ignorant of whet...
