Classical and Quantized General-Relativistic Angular Momentum
Geoffrey Compère, David A. Nichols
Angular momentum at null infinity has a supertranslation ambiguity from the lack of a preferred Poincaré group and a similar ambiguity when the center-of-mass position changes as l…
Definitions of (super) angular momentum in asymptotically flat spacetimes: Properties and applications to compact-binary mergers
Arwa Elhashash, David A. Nichols
The symmetries of asymptotically flat spacetimes in general relativity are given by the Bondi-Metzner-Sachs (BMS) group, though there are proposed generalizations of its symmetry a…
LOFAR 144-MHz follow-up observations of GW170817
J. W. Broderick, T. W. Shimwell, K. Gourdji +66
We present low-radio-frequency follow-up observations of AT 2017gfo, the electromagnetic counterpart of GW170817, which was the first binary neutron star merger to be detected by A…
Forecasts for detecting the gravitational-wave memory effect with Advanced LIGO and Virgo
Oliver M. Boersma, David A. Nichols, Patricia Schmidt
The detection of gravitational waves (GWs) from binary black holes (BBHs) has allowed the theory of general relativity to be tested in a previously unstudied regime: that of strong…
Persistent gravitational wave observables: Nonlinear plane wave spacetimes
Éanna É. Flanagan, Alexander M. Grant, Abraham I. Harte +1
In the first paper in this series, we introduced "persistent gravitational wave observables" as a framework for generalizing the gravitational wave memory effect. These observables…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1130
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis,…
