Sonification of gravitationally lensed gravitational waves / Sonificació de l'efecte de lent gravitatòria en ones gravitacionals [PDF]
Gravitational waves are oscillations of space-time that are created, for example, in black hole mergers. If these waves travel through another massive astrophysical object, they will undergo an effect called gravitational lensing, that will distort and deflect them.

Freezing-in gravitational waves
The thermal plasma in the early Universe produced a stochastic gravitational wave (GW) background, which peaks today in the microwave regime and was dubbed the cosmic gravitational microwave background (CGMB). In previous works, only single graviton production processes that contribute to the CGMB have been considered.

• On the Polarization of Gravitational Waves
Physical properties of gravitational waves, belonging to the larger class of exact solutions of Einstein field equations which are invariant for a non-Abelian two-dimensional Lie algebra of Killing fields, are described. It is shown that in the would be quantum theory of gravity they correspond to spin $−1$ massless particles.

On the Detectability of Relic (Squeezed) Gravitational Waves [PDF]
The expected amplitudes and spectral slopes of relic gravitational waves, plus their specific correlation properties associated with the phenomenon of squeezing, may allow the registration of relic (squeezed) gravitational waves by the first generation of sensitive gravity-wave detectors.
