A Fermi Gamma-Ray Burst Monitor search for electromagnetic signals coincident with gravitational-wave candidates in Advanced LIGO's first observing run
... The untargeted, ground-based analysis searches primarily for SGRBs in continuous time-tagged event data. While a full description of the untargeted search will be in a forthcoming article we present a brief description ...

Search for gravitational waves associated with the gamma ray burst GRB030329 using the LIGO detectors
... Current models suggest [2] that the gravitational-wave signature should appear close to the GRB trigger time. We conservatively chose the duration and position of the signal region to over-cover most predictions and to ...
