Would seti pick this event up at Arecibo?: News story Gamma ray bursts are not radio sources. They are accompanied by afterglows in the X, UV, visible spectral regions which are monitored by steerable telescopes soon after the first observations by the Swift, Agile, Integral and now GLAST-Fermi satellites. See grb.sonoma.edu. Tullio |

The primary event may not generate radio emissions directly, I'll concede. But any large energy event can be expected to generate radio emissions. Even a single high energy particle entering a liquid detector produces a radio signal. Thus, given the size of the black-hole event, I would have thought some signal would be detectable. However, I have no numbers to laden my hand-waving here. |

this event would be something that *cough*Einstein@home*cough* would probably pick up. Although they are currently looking for yet to be discovered quasars and such. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

You mean pulsars,I think, that is rapidly rotating neutron stars. Dr.Bruce Allen at Grenoble said that they (LIGO et al) intend also to look for binary pulsar systems. The new Einstein Telescope, now in project in Europe, should add more sensitivity to LIGO, VIRGO, GEO600 etc. Tullio |
