“…Intuitively, it is clear that measuring these waves must be difficult -the weakness of the gravitational interaction ensures that the response of any detector to gravitational waves is very small. Nonetheless, technology has brought us to the point where detectors are now beginning to set interesting upper limits on GWs from some sources [79][80][81][82]. The first direct detection could be,hopefully, not too far in the future.…”

This review paper is devoted to the theory of orbits. We start with the discussion of the Newtonian problem of motion then we consider the relativistic problem of motion, in particular the post-Newtonian (PN) approximation and the further gravitomagnetic corrections. Finally by a classification of orbits in accordance with the conditions of motion, we calculate the gravitational waves luminosity for different types of stellar encounters and orbits.

“…Transient departures from Gaussian noise that are poor matches for gravitational wave templates, or "glitches", are associated with large values of the χ 2 statistic, and this can be used to reject such noise events [2]. The χ 2 consistency test is literally the most time consuming part of the gravitational wave search pipeline.…”

“…Therefore, we propose using GPUs as a cost-effective approach to reduce the computational cost in GW searches. In this paper, we report the first test of using a GPU in a modified existing data analysis pipeline described in [2] to search for GW signals from coalescing systems of compact objects (denoted the inspiral search pipeline). A previous report can be found in [7].…”

“…Thousands of templates are required [4] to analyze a data segment for mass ranges of 1.4-11 solar masses for each individual member of the binary. In the currently running search pipeline described in [2], each data segment is made up of 256 seconds of detector data down-sampled to 4096 Hz giving 2 20 data points. This means that thousands of FFTs, each of 2 20 data points, are required to filter one data segment through the template bank.…”

Abstract. The existence of gravitational waves was predicted by Albert Einstein. Black hole and neutron star binary systems will product strong gravitational waves through their inspiral and eventual merger. The analysis of the gravitational wave data is computationally intensive, requiring matched filtering of terabytes of data with a bank of at least 3000 numerical templates that represent predicted waveforms. We need to complete the analysis in real-time (within the duration of the signal) in order to enable follow-up observations with some conventional optical or radio telescopes. We report a novel application of a graphics processing units (GPUs) for the purpose of accelerating the search pipelines for gravitational waves from coalescing binary systems of compact objects. A speed-up of 16 fold in total has been achieved with an NVIDIA GeForce 8800 Ultra GPU card compared with a standard central processing unit (CPU). We show that further improvements are possible and discuss the reduction in CPU number required for the detection of inspiral sources afforded by the use of GPUs.

On the interaction of mesoscopic quantum systems with gravity

We review the different aspects of the interaction of mesoscopic quantum systems with gravitational fields. We first discuss briefly the foundations of general relativity and quantum mechanics. Then, we consider the non-relativistic expansions of the Klein-Gordon and Dirac equations in the post-Newtonian approximation. After a short overview of classical gravitational waves, we discuss two proposed interaction mechanisms: (i) the use of quantum fluids as generator and/or detector of gravitational waves in the laboratory, and (ii) the inclusion of gravitomagnetic fields in the study of the properties of rotating superconductors. The foundations of the proposed experiments are explained and evaluated. Quantum theory and the gravitational fieldIn this introductory section we shall give a brief review of the relation between quantum theory and gravity. For more details and references we refer to [1].The gravitational interaction is distinguished by the fact that it interacts universally with all forms of energy. It dominates on large scales (relevant for cosmology) and for compact objects (such as neutron stars and black holes). All presently known features of gravitational physics are successfully described by the theory of general relativity (GR), accomplished by Albert Einstein in 1915.1 In this theory, gravity is not interpreted as a force acting on space and in time, but as a representation of the geometry of spacetime. This is a consequence of the equivalence principle stating the (local) equivalence of free fall with the gravity-free case. Mass generates curvature which in turn acts back on the mass. Curvature can also exist in vacuum; for example, it can propagate with the speed of light in the form of gravitational waves. In contrast to other physical theories, spacetime in GR plays a dynamical role and not the role of a rigid background structure.Experimentally, GR is a very successful theory [4]. Particularly impressive examples are the observations of the double pulsar PSR 1913+16 by which the existence of gravitational waves has been verified indirectly. Many interferometers on Earth are now in operation with the goal of direct observations of these waves. This would open a new window to the universe ('gravitational-wave astronomy'). After 40 years of preparation, the ambitious satellite project Gravity-Probe B was launched in April 2004 in order to observe the 'Thirring-Lense effect' predicted by GR. This effect states that a rotating mass (here the Earth) forces local inertial systems in its neighbourhood to rotate with respect to far-away objects. GR has also entered everyday life in the form of the global positioning system GPS; without the implementation of GR, inaccuracies in the order of kilometres would easily arise over the time span of days [5]. A recent survey of GR tests in space can be found in [6] and the references therein. * Corresponding author: e-mail: kiefer@thp.uni-koeln.de 1 Exceptions may be the Pioneer anomaly [2] and the rotation curves of galaxies [3], which could in principle d...
