Abstract
There are several common conventions in use by the gravitational-wave community to describe the amplitude of sources and the sensitivity of detectors. These are frequently confused. We outline the merits of and differences between the various quantities used for parameterizing noise curves and characterizing gravitational-wave amplitudes. We conclude by producing plots that consistently compare different detectors. Similar figures can be generated on-line for general use at http://rhcole.com/apps/GWplotter.

Cosmological Backgrounds of Gravitational Waves

TL;DR: In this article, the authors review early universe sources that can lead to cosmological backgrounds of GWs and discuss the basic characteristics of present and future GW detectors, including advanced LIGO, advanced Virgo, the Einstein telescope, KAGRA, and LISA.

Sensitivity curves for searches for gravitational-wave backgrounds

TL;DR: In this article, the authors proposed a graphical representation of detector sensitivity curves for stochastic gravitational-wave backgrounds that takes into account the increase in sensitivity that comes from integrating over frequency in addition to integrating over time.

The construction and use of LISA sensitivity curves

TL;DR: In this paper, the authors describe how the sensitivity curve is constructed, and how it can be used to compute the signal-to-noise ratio for a wide range of binary systems.

Nonperturbative Dynamics Of Reheating After Inflation: A Review

TL;DR: In this article, the authors provide an overview of the current understanding of the nonperturbative, nonlinear dynamics at the end of inflation, some salient features of realistic particle physics models of reheating, and how the universe reaches a thermal state before BBN.

Semianalytic calculation of gravitational wave spectrum nonlinearly induced from primordial curvature perturbations

TL;DR: In this paper, the integral integral in the expression of the power spectrum of the induced GWs, which is a universal part independent of the spectrum of primordial curvature perturbations, is analyzed.

Detection of $B$-Mode Polarization at Degree Angular Scales by BICEP2

TL;DR: An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.

Gravitational radiation from point masses in a Keplerian orbit

TL;DR: In this paper, the total rate, angular distribution, and polarization of the radiated energy are discussed for arbitrary eccentricity of the relative orbit, but assume orbital velocities are small.
