“…The recent general relativistic numerical calculations of coalescence of magnetized double NS (Yuk Tun Li et al 2008) cofirmed the crucial role of strong magnetic field in delaying the collapse of an intermediate supermassive object that forms during the coalescence process. Obviously, the magnetic field cannot be neglected when calculating the gravitational-wave templates from colaescing NS binaries, which is very important for ongoing gravitational wave detectors (Braginsky 2008, Abbott et al 2008). …”

Coalescing neutron star binaries are believed to be the most reliable sources for ground-based detectors of gravitational waves and likely progenitors of short gamma-ray bursts. In the process of coalescence, magnetic fields of neutron stars can induce interesting observational manifestations and affect the form of gravitational wave signal. In this papaer we use the population synthesis method to model the expected distribution of neutron star magnetic fields during the coalescence under different assumptions on the initial parameters of neutron stars and their magnetic field evolution. We discuss possible elecotrmagnetic phenomena preceding the coalescence of magnetized neutron star binaries and the effect of magnetic field on the gravitational wave signal. We find that a log-normal (Gaussian in logarithms) distribution of the initial magnetic fields of neutron stars, which agrees with observed properties of radio pulsars, produces the distribution of the magnetic field energy during the coalescence that adequately describes the observed luminosity function of short gamma-ray bursts under different assumptions on the field evolution and initial parameters of neutron stars. This agreement lends further support to the model of coalescing neutron star binaries as progenitors of gamma-ray bursts.

“…Several excellent monographs (Giazotto, 1989;Saulson, 1994;Barish and Weiss, 1999;Weiss, 1999;Aufmuth and Danzmann, 2005;Braginsky, 2008;Freise and Strain, 2010;Cella and Giazotto, 2011;Pitkin et al, 2011) have been written on the techniques of gravitational-wave detection by laser interferometry. In this review, we discuss the current state of gravitational-wave detectors, describing in detail the fundamental limits to their astrophysical reach, and then present prospects for the future.…”

Gravitational radiation detection with laser interferometry

2014

View full text Add to dashboard Cite

Gravitational-wave detection has been pursued relentlessly for over 40 years. With the imminent operation of a new generation of laser interferometers, it is expected that detections will become a common occurrence. The research into more ambitious detectors promises to allow the field to move beyond detection and into the realm of precision science using gravitational radiation. In this article, the state of art for the detectors is reviewed and an outlook for the coming decades is described.

“…In particular, a direct detection of gravitational waves is supposed to come from laserinterferometric detectors [1][2][3], where they induce a measurable variation of the optical paths of the light beams traveling along the arms of an interferometric setup.…”

“…Interferometric setups are at the heart of several highprecision measurement schemes, ranging from gravitational wave-detectors to laser gyroscopes and clocks synchronization protocols. In particular, a direct detection of gravitational waves is supposed to come from laserinterferometric detectors [1][2][3], where they induce a measurable variation of the optical paths of the light beams traveling along the arms of an interferometric setup.…”

The Lindley paradox in optical interferometry

The so-called Lindley paradox is a counterintuitive statistical effect where the Bayesian and frequentist approaches to hypothesis testing give radically different answers, depending on the choice of the prior distribution. In this paper we address the occurrence of the Lindley paradox in optical interferometry and discuss its implications for high-precision measurements. In particular, we focus on phase estimation by Mach-Zehnder interferometers and show how to mitigate the conflict between the two approaches by using suitable priors.
