Low-frequency terrestrial gravitational-wave detectors

TLDR
In this article, the authors examined the potential sensitivity of three ground-based detector concepts aimed at radiation in the 0.1-10 Hz band and made estimates for their event rates and thereby, the sensitivity requirements for these detectors.
Abstract
Direct detection of gravitational radiation in the audio band is being pursued with a network of kilometer-scale interferometers (LIGO, Virgo, KAGRA). Several space missions (LISA, DECIGO, BBO) have been proposed to search for sub-hertz radiation from massive astrophysical sources. Here we examine the potential sensitivity of three ground-based detector concepts aimed at radiation in the 0.1--10 Hz band. We describe the plethora of potential astrophysical sources in this band and make estimates for their event rates and thereby, the sensitivity requirements for these detectors. The scientific payoff from measuring astrophysical gravitational waves in this frequency band is great. Although we find no fundamental limits to the detector sensitivity in this band, the remaining technical limits will be extremely challenging to overcome.

Detection methods for stochastic gravitational-wave backgrounds: a unified treatment

TL;DR: The article considers both Bayesian and frequentist searches using ground-based and space-based laser interferometers, spacecraft Doppler tracking, and pulsar timing arrays; and it allows for anisotropy, non-Gaussianity, and non-standard polarization states.

Gravitational wave detection with optical lattice atomic clocks

TL;DR: In this paper, a space-based gravitational wave (GW) detector consisting of two spatially separated, drag-free satellites sharing ultrastable optical laser light over a single baseline is proposed.

Detection methods for stochastic gravitational-wave backgrounds: a unified treatment

TL;DR: In this paper, a review of detection methods that have been used or have been proposed to search for a stochastic background of gravitational radiation is presented, focusing on relevant data analysis issues, and not on the particular astrophysical or early Universe sources that might give rise to such background.
Journal ArticleDOI

Terrestrial gravity fluctuations

TL;DR: The article reviews the current state of the field, and presents new analyses especially with respect to the impact of seismic scattering on gravity perturbations, active gravity noise cancellation, and time-domain models of gravity perturgations from atmospheric and seismic point sources.

Atmospheric pollution profiles in Mexico City in two different seasons

TL;DR: In this article, a CO2-laser-based photoacoustic spectrometer was used to determine the temporal concentration profile of atmospheric ethene in Mexico City, and the results of this campaign were compared with data obtained in the winter of 2001.

Gravitational Radiation and the Motion of Two Point Masses

TL;DR: In this article, it was shown that, regardless of coordinate systems or conditions, the energy of a system must decrease as a result of the radiation of gravitational waves, providing the potentials are inversely proportional to the distance from the source for large distances.
