Spin doctors Meg Millhouse, Lucy Strang and Karl Wette are using gravitational-wave detectors to study rotating neutron stars. (Courtesy: OzGrav) The LIGO–Virgo observatories are three kilometre-scale ...

All sensors have a threshold, defined by the smallest signal amplitude that can be detected. The detection of sub-threshold signals, however, is possible by using the principle of stochastic resonance ...

Built upon the ubiquitous Fourier transform, the mathematical tools known as wavelets allow unprecedented analysis and understanding of continuous signals. In an increasingly data-driven world, ...
