We anticipate noise from the Laser Interferometer Space Antenna (LISA) will exhibit nonstationarities throughout the duration of its mission due to factors such as antenna repointing, cyclostationarities from spacecraft motion, and glitches as highlighted by LISA Pathfinder. In this paper, we use a surrogate data approach to test the...

Gravitational wave detectors like the Einstein Telescope and LISA generate long multivariate time series, which pose significant challenges in spectral density estimation due to a number of overlapping signals as well as the presence of correlated noise. Addressing both issues is crucial for accurately interpreting the signals detected by these...

The eventual detection of gravitational waves from core-collapse supernovae (CCSNe) will help improve our current understanding of the explosion mechanism of massive stars. The stochastic nature of the late postbounce gravitational wave signal due to the nonlinear dynamics of the matter involved and the large number of degrees of freedom of the...
