We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and 20M☉. Optimally oriented binaries with distances up to 1 Mpc could be detected with efficiency of at least 90%. We found no events that could be identified as gravitational waves in the 385.6 hours of data that we searched.

    • "As shown in figure 5, this range is (or it will be) covered by multiple probes. The ground-based network of advanced interferometric detectors (three LIGO detectors, VIRGO [67], and the Kamioka Gravitational wave Detector, KAGRA [68]) and possibly the third-generation Einstein Telescope (ET, [69]) will observe inspiralling binaries up to around few×100 M . The milli-Hz regime will be the hunting territory of spaced based detectors such as eLISA, whereas PTAs are already probing the nano-Hz portion of the frequency band. "

    ABSTRACT: Massive black hole binaries (MBHBs) are unavoidable outcomes of the hierarchical structure formation process, and according to the theory of general relativity are expected to be the loudest gravitational wave (GW) sources in the Universe. In this article I provide a broad overview of MBHBs as GW sources. After reviewing the basics of GW emission from binary systems and of MBHB formation, evolution and dynamics, I describe in some details the connection between binary properties and the emitted gravitational waveform. Direct GW observations will provide an unprecedented wealth of information about the physical nature and the astrophysical properties of these extreme objects, allowing to reconstruct their cosmic history, dynamics and coupling with their dense stellar and gas environment. In this context I describe ongoing and future efforts to make a direct detection with space based interferometry and pulsar timing arrays, highlighting the invaluable scientific payouts of such enterprises.

    • "The LIGO Scientific Collaboration (LSC) [8] and Virgo [9] [10] each have search pipelines for binary inspiral events, and studies have shown that these pipelines have equivalent detection capabilities [11]. The LSC has conducted searches for binary neutron star inspirals [8] [12], primordial black hole binary coalescences in the galactic halo [13], and black hole binaries [14]. The LSC and TAMA have conducted a joint search for binary neutron star systems [15], and soon the LSC and Virgo will be conducting collaborative searches [11]. "

    ABSTRACT: We present in this paper a Bayesian parameter estimation method for the analysis of interferometric gravitational wave observations of an inspiral of binary compact objects using data recorded simultaneously by a network of several interferometers at different sites. We consider neutron star or black hole inspirals that are modeled to 3.5 post-Newtonian (PN) order in phase and 2.5 PN in amplitude. Inference is facilitated using Markov chain Monte Carlo methods that are adapted in order to efficiently explore the particular parameter space. Examples are shown to illustrate how and what information about the different parameters can be derived from the data. This study uses simulated signals and data with noise characteristics that are assumed to be defined by the LIGO and Virgo detectors operating at their design sensitivities. Nine parameters are estimated, including those associated with the binary system, plus its location on the sky. We explain how this technique will be part of a detection pipeline for binary systems of compact objects with masses up to $20 \sunmass$, including cases where the ratio of the individual masses can be extreme.

    • "One well-studied phenomenon which is expected to be a source of gravitational waves is the inspiral and coalescence of a pair of dense, massive astrophysical objects such as neutron stars and black holes. Such binary inspiral signals are among the most promising sources for LIGO [8] [9]. Gravitational waves interact extremely weakly with matter, and the measurable effects produced in terrestrial instruments by their passage will be miniscule. "

    ABSTRACT: In this paper we examine the issue of optimizing disk usage and scheduling large-scale scientific workflows onto distributed resources where the workflows are data-intensive, requiring large amounts of data storage, and the resources have limited storage resources. Our approach is two-fold: we minimize the amount of space a workflow requires during execution by removing data files at runtime when they are no longer needed and we demonstrate that workflows may have to be restructured to reduce the overall data footprint of the workflow. We show the results of our data management and workflow restructuring solutions using a Laser Interferometer Gravitational-Wave Observatory (LIGO) application and an astronomy application, Montage, running on a large-scale production grid-the Open Science Grid. We show that although reducing the data footprint of Montage by 48% can be achieved with dynamic data cleanup techniques, LIGO Scientific Collaboration workflows require additional restructuring to achieve a 56% reduction in data space usage. We also examine the cost of the workflow restructuring in terms of the application's runtime.
