- Descrição
- The peculiar phenomenology of soft gamma-ray repeaters (SGRs) have been evidenced once again during the August 27, 1998 outburst from SGR 1900+14. Its powerful energy release could have make it possible for a gravitational-wave (GW) burst to be produced almost simultaneously with the ?–burst. Integrating in an unique scheme the most recent observational data on the energetics and timescales of the event, together with the strong-field relativistic gravity binary scenario [12] and the mechanism for triggering the GW and ?–rays signals as suggested recently [1,2], I have estimated the characteristics of the pulse for a wide range of reliable parameters of the model. I conclude that such a signal should have been detected even by the third generation of GW detectors in operation at the onset of the burst: ALLEGRO, EXPLORER, etc., as well as by LIGO, VIRGO and GEO-600 [3,4], were they operationals. Because of the fundamental impact for physics, and science in general, such a detection might have, an urgent search for evidences for or constraints on the occurrence of this event on archival data of such detectors is timely.
