Search for Gravitational Waves Associated with GammaRay Bursts during the First Advanced LIGO Observing Run and Implications for the Origin of GRB 150906B
Abstract
We present the results of the search for gravitational waves (GWs) associated with γray bursts detected during the first observing run of the Advanced Laser Interferometer GravitationalWave Observatory (LIGO). We find no evidence of a GW signal for any of the 41 γray bursts for which LIGO data are available with sufficient duration. For all γray bursts, we place lower bounds on the distance to the source using the optimistic assumption that GWs with an energy of {10}^{2}{M}_{⊙ }{c}^{2} were emitted within the 16500 Hz band, and we find a median 90% confidence limit of 71 Mpc at 150 Hz. For the subset of 19 short/hard γray bursts, we place lower bounds on distance with a median 90% confidence limit of 90 Mpc for binary neutron star (BNS) coalescences, and 150 and 139 Mpc for neutron starblack hole coalescences with spins aligned to the orbital angular momentum and in a generic configuration, respectively. These are the highest distance limits ever achieved by GW searches. We also discuss in detail the results of the search for GWs associated with GRB 150906B, an event that was localized by the InterPlanetary Network near the local galaxy NGC 3313, which is at a luminosity distance of 54 Mpc (z = 0.0124). Assuming the γray emission is beamed with a jet halfopening angle ≤slant 30^\circ , we exclude a BNS and a neutron starblack hole in NGC 3313 as the progenitor of this event with confidence >99%. Further, we exclude such progenitors up to a distance of 102 Mpc and 170 Mpc, respectively.
