Narrowband searches for continuous and long-duration transient gravitational waves from known pulsars in the LIGO-Virgo third observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1658

Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully-coherent s…

Gravitational Lensing in the Charged NUT-de Sitter Spacetime

Torben C. Frost

It is a long-standing open question if a gravitomagnetic charge, the gravitational analogon to a hypothetical magnetic charge in electrodynamics, exists in nature. It naturally occ…

Turbulent magnetic field amplification in binary neutron star mergers

C. Palenzuela, R. Aguilera-Miret, F. Carrasco +5

Magnetic fields are expected to play a key role in the dynamics and the ejection mechanisms that accompany the merger of two neutron stars. General relativistic magnetohydrodynamic…

Tests of General Relativity with GWTC-3

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1682

The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensiti…

Model systematics in time domain tests of binary black hole evolution

Shilpa Kastha, Collin D. Capano, Julian Westerweck +3

We perform several consistency tests between different phases of binary black hole dynamics; the inspiral, the merger, and the ringdown on the gravitational wave events GW150914 an…

Two body dynamics in a quadratic modification of general relativity

Soham Bhattacharyya

It is shown in this study that deviations from the Einstein-Hilbert action at the quadratic level using a proper analyses and suitable dynamical variables lead to a tiny modificati…
