TLDR

Abstract
Large gravitational wave interferometric detectors, like Virgo and LIGO, demonstrated the capability to reach their design sensitivity, but to transform these machines into an effective observational instrument for gravitational wave astronomy a large improvement in sensitivity is required. Advanced detectors in the near future and third-generation observatories in more than one decade will open the possibility to perform gravitational wave astronomical observations from the Earth. An overview of the possible science reaches and the technological progress needed to realize a third-generation observatory are discussed in this paper. The status of the project Einstein Telescope (ET), a design study of a third-generation gravitational wave observatory, will be reported.

The Einstein Telescope: a third-generation gravitational wave observatory

M. Punturo, +134 more
TL;DR: The third-generation ground-based observatory Einstein Telescope (ET) project as discussed by the authors is currently in its design study phase, and it can be seen as the first step in this direction.

Quasinormal modes of black holes: From astrophysics to string theory

TL;DR: In this paper, a review of recent achievements on various aspects of black hole perturbations are discussed such as decoupling of variables in the perturbation equations, quasinormal modes (with special emphasis on various numerical and analytical methods of calculations), late-time tails, gravitational stability, anti-de Sitter/conformal field theory interpretation, and holographic superconductors.

Sensitivity studies for third-generation gravitational wave observatories

Stefan Hild, +141 more
TL;DR: In this article, a special focus is set on evaluating the frequency band below 10 Hz where a complex mixture of seismic, gravity gradient, suspension thermal and radiation pressure noise dominates, including the most relevant fundamental noise contributions.

Evolution of binary black-hole spacetimes.

TL;DR: Early success is described in the evolution of binary black-hole spacetimes with a numerical code based on a generalization of harmonic coordinates capable of evolving binary systems for enough time to extract information about the orbit, merger, and gravitational waves emitted during the event.

Determining the Hubble constant from gravitational wave observations

TL;DR: In this paper, the nearly monochromatic gravitational waves emitted by the decaying orbit of an ultra-compact, two-neutron-star binary system just before the stars coalesce are used to determine the absolute distance to the binary, independently of any assumptions about the masses of the stars.

Accurate Evolutions of Orbiting Black-Hole Binaries without Excision

TL;DR: A new algorithm for evolving orbiting black-hole binaries that does not require excision or a corotating shift is presented and fourth-order convergence of waveforms is shown and the radiated gravitational energy and angular momentum from the plunge is computed.

Effective one-body approach to general relativistic two-body dynamics

TL;DR: In this article, the authors map the general relativistic two-body problem onto that of a test particle moving in an effective external metric, and define, in a nonperturbative manner, the late dynamical evolution of a coalescing binary system of compact objects.

LIGO: The laser interferometer gravitational-wave observatory

TL;DR: LIGO as discussed by the authors is a trio of extremely sensitive Michelson interferometers built to detect gravitational waves from space, and the results of their recent observations are described in detail.
