Vecchio Date: 10 Oct 2007 Abstract: Inspiral signals from binary compact objects (black holes and neutron stars) are primary targets of the ongoing searches by a number of ground-based gravitational-wave interferometers (LIGO, Virgo, GEO-600 and TAMA-300). Detection of such inspirals and ensuing mergers is expected to provide us with important physical information about the properties of the sources, bearing on outstanding issues in compact-object astrophysics, including the progenitors of short gamma-ray bursts. Compact-object spin effects add to the challenges associated with searches and anticipated detections, but on the other hand they provide some interesting possibilities for extracting astrophysical information. We present parameter-estimation simulations for inspirals of black-hole binaries with neutron-star companions using Markov-Chain Monte-Carlo methods. We specifically highlight the potential for measurements of masses, spins, source sky location and distance of such objects with just one or two gravitational-wave detectors. |
