Abstract:

An analysis of the time correlation between Gamma-Ray Bursts from BATSE detector and EXPLORER Gravitational Wave Antenna data was performed from april 1991 to december 1996. A time interval of $\pm 5$ minutes around the trigger time of Gamma-Ray Bursts (GRBs) was explored. No significant excess of coincidences between GRBs and EXPLORER events with an energy of about 100 mK was found. This result allows to exclude correlations with 1 ms Gravitational Wave (GW) bursts with amplitude: $h \ge 2.5 \ 10^{-18}$ .

Key words: gravitational waves -- gamma-ray: bursts

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
