A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

Gravitational waves from binary black hole and neutron star mergers are being regularly
detected. As of 2021, 90 confident gravitational wave detections have been made by the …

The global network of gravitational-wave observatories now includes five detectors, namely
LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected …

We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

The Advanced LIGO and Advanced Virgo gravitational-wave (GW) detectors will begin
operation in the coming years, with compact binary coalescence events a likely source for …

Between July 2009 and October 2010, the Laser Interferometer Gravitational-Wave
Observatory (LIGO)[1] operated two 4 km laser interferometers as part of a global network …

A central challenge in gravitational wave astronomy is identifying weak signals in the
presence of non-stationary and non-Gaussian noise. The separation of gravitational wave …

Around the globe several observatories are seeking the first direct detection of gravitational
waves (GWs). These waves are predicted by Einstein's general theory of relativity and are …

We present a detailed, three-dimensional hydrodynamic study of the neutrino-driven winds
emerging from the remnant of a neutron star merger. Our simulations are performed with the …

Advanced gravitational wave detectors, currently under construction, are expected to directly
observe gravitational wave signals of astrophysical origin. The Einstein Telescope (ET), a …
