The sensitivity of gravitational waves detectors keeps improving and we should expect to find gravitationally lensed gravitational waves soon. Since the number of detections is [...]

Rapidly spinning, non-axisymmetric neutron stars (NSs) are expected to emit continuous gravitational waves (CWs). Detecting such signals would significantly improve our understanding of the galactic [...]

The increase in sensitivity and detector upgrades planned in the coming years will challenge existing waveform models and demand considerable improvements in accuracy, parameter space [...]

The current phenomenological waveform models for binary black hole mergers do not include the (l=2, m=0) spherical harmonic, which is the only mode with l=2 [...]

Precessing binaries exhibit complex dynamics that significantly modulate the emitted gravitational waveform. Describing such systems is challenging due to the lack of a canonical choice [...]

Solutions to the Einstein Equations that are close to the threshold of black hole formation exhibit features that resemble critical phenomena in statistical mechanics. We [...]

Gravitational wave memory is characterized by a signal component that persists after a transient signal has decayed. Treating such signals in the frequency domain is [...]

State-of-the-art gravitational waveform models need input from many frameworks tackling the relativistic two-body problem. Among them are the gravitational self-force approach, which was designed to [...]

There are a wide variety of phenomena in solar prominences, such as waves, instabilities or mass flows. Observations have shown the ubiquitous presence of MHD [...]
