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…
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…
Search of the Early O3 LIGO Data for Continuous Gravitational Waves from the Cassiopeia A and Vela Jr. Supernova Remnants
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1411
We present directed searches for continuous gravitational waves from the neutron stars in the Cassiopeia A (Cas A) and Vela Jr. supernova remnants. We carry out the searches in the…
A general framework for gravitational charges and holographic renormalization
Venkatesa Chandrasekaran, Eanna E. Flanagan, Ibrahim Shehzad +1
We develop a general framework for constructing charges associated with diffeomorphisms in gravitational theories using covariant phase space techniques. This framework encompasses…
A scalable elliptic solver with task-based parallelism for the SpECTRE numerical relativity code
Nils L. Vu, Harald P. Pfeiffer, Gabriel S. Bonilla +10
Elliptic partial differential equations must be solved numerically for many problems in numerical relativity, such as initial data for every simulation of merging black holes and n…
Fractality in Cosmic Topology Models with Spectral Action Gravity
Pedro Guicardi, Matilde Marcolli
We consider cosmological models based on the spectral action formulation of (modified) gravity. We analyze the coupled effects, in this model, of the presence of nontrivial cosmic…
High Precision Ringdown Modeling: Multimode Fits and BMS Frames
Lorena Magaña Zertuche, Keefe Mitman, Neev Khera +12
Quasi-normal mode (QNM) modeling is an invaluable tool for characterizing remnant black holes, studying strong gravity, and testing GR. Only recently have QNM studies begun to focu…
All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…
Conservation of asymptotic charges from past to future null infinity: Lorentz charges in general relativity
Kartik Prabhu, Ibrahim Shehzad
We show that the asymptotic charges associated with Lorentz symmetries on past and future null infinity match in the limit to spatial infinity in a class of asymptotically-flat spa…
The NANOGrav 12.5-year data set: Search for Non-Einsteinian Polarization Modes in theGravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +68
We search NANOGrav's 12.5-year data set for evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity. We fi…
Simulating magnetized neutron stars with discontinuous Galerkin methods
Nils Deppe, François Hébert, Lawrence E. Kidder +33
Discontinuous Galerkin methods are popular because they can achieve high order where the solution is smooth, because they can capture shocks while needing only nearest-neighbor com…

Nils Deppe, François Hébert, Lawrence E. Kidder +1
We present a discontinuous Galerkin-finite-difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohy…

We study the oscillations modes of differential rotating remnants of binary neutron star inspirals by modeling them as incompressible Riemann ellipsoids parametrized by the ratio $…
Efficient simulations of high-spin black holes with a new gauge
Yitian Chen, Nils Deppe, Lawrence E. Kidder +1
We present a new choice of initial data for binary black hole simulations that significantly improves the efficiency of high-spin simulations. We use spherical Kerr-Schild coordina…
All-sky search for long-duration gravitational-wave bursts in the third Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
After the detection of gravitational waves from compact binary coalescences, the search for transient gravitational-wave signals with less well-defined waveforms for which matched…
Universal features of gravitational waves emitted by superkick binary black hole systems
Sizheng Ma, Matthew Giesler, Vijay Varma +2
We use numerical relativity to study the merger and ringdown stages of "superkick" binary black hole systems (those with equal mass and anti-parallel spins). We find a universal wa…
