Pulsar timing array projects
TL;DR: A review of current and future pulsar timing array projects can be found in this paper, where the authors review the goals and status of current pulsar array projects and compare observations of many such stable pulsars, which may allow direct detection of gravitational waves, improve the Solar System planetary ephemeris and provide a means to study irregularities in terrestrial time scales.

Abstract: Pulsars are amongst the most stable rotators known in the Universe. Over many years some millisecond pulsars rival the stability of atomic clocks. Comparing observations of many such stable pulsars may allow the first direct detection of gravitational waves, improve the Solar System planetary ephemeris and provide a means to study irregularities in terrestrial time scales. Here we review the goals and status of current and future pulsar timing array projects.

Signatures of the neutrino thermal history in the spectrum of primordial gravitational waves
TL;DR: In this paper, the authors studied the effect of the anisotropic stress generated by neutrinos on the propagation of primordial cosmological gravitational waves and calculated the maximum possible amount of damping, corresponding to the case of a flat universe completely dominated by ultrarelativistic collisionless particles.
