Abstract
With the detection of gravitational wave emissions from from merging
compact objects, it is now more important than ever to effectively mine the
data-set of gamma-satellites for non-triggered, short-duration transients.
Hence we developed a new method called the Automatized Detector Weight
Optimization (ADWO), applicable for space-borne detectors such as Fermi's GBM
and RHESSI's Ge detectors. Provided that the trigger time of an astrophysical event is
well known (as in the case of a gravitational wave detection) but the detector
response matrix is uncertain, ADWO combines the data of all detectors and
energy channels to provide the best signal-to-noise ratio. We used ADWO to
successfully identify any potential electromagnetic counterpart of
gravitational wave events, as well as to detect previously un-triggered
short-duration GRBs in the data-sets.
