Correlator bank detection of gravitational wave chirpsFalsealarm probability, template density, and thresholds: Behind and beyond the minimalmatch issue
Abstract
The general problem of computing the falsealarm probability vs the detectionthreshold relationship for a bank of correlators is addressed, in the context of maximumlikelihood detection of gravitational waves in additive stationary Gaussian noise. Specific reference is made to chirps from coalescing binary systems. Accurate (lowerbound) approximants for the cumulative distribution of the wholebank supremum are deduced from a class of Bonferronitype inequalities. The asymptotic properties of the cumulative distribution are obtained, in the limit where the number of correlators goes to infinity. The validity of numerical simulations made on smallsize banks is extended to banks of any size, via a Gaussiancorrelation inequality. The result is used to readdress the problem of relating the template density to the fraction of potentially observable sources which could be dismissed as an effect of template space discreteness.

The list of putative sources of gravitational waves possibly detected by the ongoing worldwide network of large scale interferometers has been continuously growing in the last years. For some of them, the detection is made difficult by the lack of a complete information about the expected signal. We concentrate on the case where the expected gravitational wave (GW) is a quasiperiodic frequency modulated signal i.e., a chirp. In this article, we address the question of detecting an a priori unknown GW chirp. We introduce a general chirp model and claim that it includes all physically realistic GW chirps. We producemore »

Best network chirplet chain: Nearoptimal coherent detection of unmodeled gravitational wave chirps with a network of detectors
The searches of impulsive gravitational waves (GW) in the data of the groundbased interferometers focus essentially on two types of waveforms: short unmodeled bursts from supernova core collapses and frequency modulated signals (or chirps) from inspiralling compact binaries. There is room for other types of searches based on different models. Our objective is to fill this gap. More specifically, we are interested in GW chirps ''in general,'' i.e., with an arbitrary phase/frequency vs time evolution. These unmodeled GW chirps may be considered as the generic signature of orbiting or spinning sources. We expect the quasiperiodic nature of the waveform tomore » 
TanakaTagoshi parametrization of postfirstpostNewtonian spinfree gravitational wave chirps: Equispaced and cardinal interpolated lattices for first generation interferometric antennas
The spinfree binaryinspiral parameterspace introduced by Tanaka and Tagoshi to construct a uniformly spaced lattice of postfirstpost Newtonian (PN) templates is shown to work for all first generation interferometric gravitational wave antennas. This allows us to extend the minimumredundant cardinal interpolation techniques of the correlator bank developed by the authors to the highest available order PN templates. The total number of templates to be computed for a minimal match {Gamma}=0.97 is reduced by a factor 4, as in the 1PN case. 
FALSEALARM PROBABILITY IN RELATION TO OVERSAMPLED POWER SPECTRA, WITH APPLICATION TO SUPERKAMIOKANDE SOLAR NEUTRINO DATA
The term 'falsealarm probability' denotes the probability that at least one out of M independent power values in a prescribed search band of a power spectrum computed from a whitenoise time series is expected to be as large as or larger than a given value. The usual formula is based on the assumption that powers are distributed exponentially, as one expects for power measurements of normally distributed random noise. However, in practice, one typically examines peaks in an oversampled power spectrum. It is therefore more appropriate to compare the strength of a particular peak with the distribution of peaks inmore » 
Template bank for gravitational waveforms from coalescing binary black holes: Nonspinning binaries
Gravitational waveforms from the inspiral and ringdown stages of the binary blackhole coalescences can be modeled accurately by approximation/perturbation techniques in general relativity. Recent progress in numerical relativity has enabled us to model also the nonperturbative merger phase of the binary blackhole coalescence problem. This enables us to coherently search for all three stages of the coalescence of nonspinning binary black holes using a single template bank. Taking our motivation from these results, we propose a family of template waveforms which can model the inspiral, merger, and ringdown stages of the coalescence of nonspinning binary black holes that follow quasicircularmore »
