Resonant-mass gravitational wave detectors are reviewed from the concept of gravitational
waves and its mathematical derivation, using Einstein's general relativity, to the present …

Stellar core collapse events are expected to produce gravitational waves via several
mechanisms, most of which are not yet fully understood due to the current limitations in the …

Superposition of gravitational waves generated by astrophysical sources is expected to give
rise to the stochastic gravitational-wave background. We focus on the background …

The Brazilian Mario Schenberg gravitational-wave detector was initially designed in the
early 2000s and remained operational until 2016 when it was disassembled. To assess the …

Abstract The Brazilian spherical antenna (Schenberg) is planned to detect high frequency
gravitational waves (GWs) ranging from 3.0 kHz to 3.4 kHz. There is a host of astrophysical …

There is in the literature a number of papers addressing the stochastic background of
gravitational waves (GWs) generated by an ensemble of astrophysical sources. The main …

Superconducting reentrant cavities may be used in parametric transducers for resonant-
mass gravitational wave detectors. When coupled to a spherical resonant antenna …
