In this work, quantitative estimates are made of the gravitational wave background produced in typical frequency ranges from such sources emitting over a Hubble time and the fluctuations in the h values measured in the usual devices. Also estimates are made of the high frequency thermal background...

Increasing the sensitivity of a gravitational-wave (GW) detector improves our ability to measure the characteristics of detected sources. It also increases the number of weak signals that contribute to the data. Because GW detectors have nearly all-sky sensitivity, they can be subject to a ...
they may appear as a background created as a polyphonic chorus superposition of different voices: those of populations of astrophysical sources born and evolved in the past, or those coming from matter and energy fluctuations in the first instant of life of the Universe. In this paper we will...
The dimensionless string tension, Gμcs, significantly influences the stochastic gravitational wave background (SGWB) produced by cosmic strings post-inflation. The SGWB from cosmic strings is shaped by the energy scales of inflation and the string formation, with the amplitude of tensor mode ...
Wave generation and sourcesNumerical studies of black holes and black-hole binariesWe compute the gravitational wave background (GWB) generated by a cosmological population of (BH-BH) binaries using hybrid waveforms recently produced by numerical simulations of (BH-BH) coalescence, which include the...

The 100 years since the publication of Albert Einstein’s theory of general relativity saw significant development of the understanding of the theory, the identification of potential astrophysical sources of sufficiently strong gravitational waves and development of key technologies for gravitational-wave det...
