...15M( spinning progenitor (model m15b6). The latter of these would be detectable throughout most of our Galaxy. A merger of two 10M( BHs would be detectable out to a distance of approximately 3 Mpc, while a merger of two 50M( BHs could be detected as far away as $120Mpc. 7.2.3. Analysis results: externally triggered burst searches. The exceptionally intense GRB 070201 was a particularly interesting event for a triggered burst search because the sky position, determined from the gamma-ray data, overlapped one of the spiral arms of the large, nearby galaxy M31 (Andromeda). An analysis of GW data [81] found no evidence of an inspiral or a more general burst signal; that finding ruled out (at the $99% level) the possibility of a binary merger in M31 being the origin of GRB 070201. We have searched for GW bursts associated with the giant flare of SGR 1806 # 20 that occurred on 27 December 2004 (between the S4 and S5 runs, but at a time when the LIGO H1 detector was operating, albeit with reduced sensitivity) plus 190 smaller flares of SGRs 1806#20 and 1900+14 during the S5 run [82]. No GW signals were identified. Energy emission limits were established for a variety of hypothetical waveforms...

...Xrays and γ-rays [8]. The exceptional energetics of this hyperflare makes of SGR 1806-20 an attractive candidate source of UHECRs, high energy neutrinos, and gravitational waves [9]. Given that the source is in our Galaxy, if it were to generate high energy neutrons a significant fraction of them could arrive at Earth before decaying and would point back to the source. Moreover, neutrons that decay in flight would produce antineutrinos that inherit directionality [10]. Searches for neutrino and gravitational wave emission have been reported by the AMANDA [11], AURIGA [12], and LIGO Scientific [13] collaborations. In all these searches the data revealed no significant signals. Cosmic Ray Data Sample In our analysis we use data collected with the Pierre Auger Observatory, located in Argentina at Southern latitude 35.2◦ and Western longitude 69.3◦. We consider events with zenith angle θ < θmax = 60 ◦, detected from January 1, 2004 to April 1, 2007. We employ the reconstruction procedure discussed elsewhere [14]. A total of 609,161 CRs have passed the selection criteria. FERMILAB-CONF-07-381-A-TD SEARCH FOR COINCIDENCES BETWEEN AUGER DATA AND ASTROPHYSICAL TRANSIENTS ° +180 ° -180 ° +90 ° ...
