Coherently searching for spinning compact binary coalescences
Speaker(s): Stephen Fairhurst
Abstract: In this talk we present the motivation behind our implementation of and results from a coherent search for spinning compact binary coalescences. Our method uses the Physical template family of waveforms which describe binaries where only one of the objects has spin. In addition we discuss the possib... read more

Comparing the performances of coherent and coincident network searches forbinary black hole mergers
Speaker(s): Thilina Dayanga
Abstract: A coherent multi-site search is expected to be more powerful than itscoincident counterpart in discriminating gravitational wave (GW) signals fromthe noise background. This is because the former tests the consistency of thesignals' amplitudes phases and time-delays across the sites with those expect... read more

Modelling waveforms from binary neutron stars
Speaker(s): Jocelyn Read
Abstract: The familiar post-Newtonian inspiral description of a binary neutron star system is sufficient for detection in current instruments. However, as we consider making astrophysical measurements using advanced detectors, the effects of matter and strong gravity on gravitational wave signals may become s... read more

Fully General Relativistic Simulations of Black Hole-Neutron Star Mergers: A Current Overview
Speaker(s): Zachariah Etienne
Abstract: Black hole-neutron star binary (BHNS) mergers are likely sources for detectable gravitational radiation and candidate engines for short-hard gamma-ray bursts. However, accurate modeling of these mergers requires fully general relativistic simulations, incorporating both relativistic hydrodynamics fo... read more

Mergers of Binary Black Holes as Burst Sources

Parameter estimation and model selection using spinning hybrid waveforms.
Speaker(s): Vivien Raymond
Abstract: Most searches with ground-based detectors for gravitational-wave signals from the inspirals of stellar-mass compact binaries use template based methods. Those work well for non-spinning systems but since the dimensionality of the parameter space of spinning waveforms is large a template bank search ... read more

Achievable Directional Reconstruction for Gravitational waves generated by Binary Systems.
Speaker(s): MIchele Zanolin
Abstract: Recently generated asymptotic expansions zanolin et al. arXiv:0912.0065 [gr-qc] showa frequentist approach to go beyond Fisher information assessments of the accuracy for maximum likelihood parameter estimations. In this talk we describe the application of these techniques to directional reconstruct... read more

Complete phenomenological spin-Taylor waveforms for generic spins
Speaker(s): Riccardo Sturani
Abstract: The quest for gravitational waves from binary inspiral is performed via matched filtering and thus requires a detailed knowledge of the signal. For non-precessing binaries complete analytic waveforms exist from inspiral to merger and ring-down. Here we present complete waveforms for generically spin... read more
