Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves
Fosca Al Roumi, Thomas Buchert, Alexander Wiegand
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the…
Cubic interactions of massless bosonic fields in three dimensions
Karapet Mkrtchyan
Parity-even cubic vertices of massless bosons of arbitrary spins in three dimensional Minkowski space are classified in the metric-like formulation. As opposed to higher dimensions…
Integrable lattice spin models from supersymmetric dualities
Ilmar Gahramanov, Shahriyar Jafarzade
Recently, there has been observed an interesting correspondence between supersymmetric quiver gauge theories with four supercharges and integrable lattice models of statistical mec…
Targeted numerical simulations of binary black holes for GW170104
James Healy, Jacob Lange, Richard O'Shaughnessy +22
In response to LIGO's observation of GW170104, we performed a series of full numerical simulations of binary black holes, each designed to replicate likely realizations of its dyna…
Assessing the Energetics of Spinning Binary Black Hole Systems
Serguei Ossokine, Tim Dietrich, Evan Foley +2
In this work we study the dynamics of spinning binary black hole systems in the strong field regime. For this purpose we extract from numerical relativity simulations the binding e…
The Einstein@Home Gamma-Ray Pulsar Survey II. Source Selection, Spectral Analysis and Multi-wavelength Follow-up
J. Wu, C. J. Clark, H. J. Pletsch +23
We report on the analysis of 13 gamma-ray pulsars discovered in the Einstein@Home blind search survey using Fermi Large Area Telescope (LAT) Pass 8 data. The 13 new gamma-ray pulsa…
Coincident detection significance in multimessenger astronomy
Gregory Ashton, Eric Burns, Tito Dal Canton +6
We derive a Bayesian criterion for assessing whether signals observed in two separate data sets originate from a common source. The Bayes factor for a common vs. unrelated origin o…
Gravitational-wave luminosity of binary neutron stars mergers
Francesco Zappa, Sebastiano Bernuzzi, David Radice +2
We study the gravitational-wave peak luminosity and radiated energy of quasicircular neutron star mergers using a large sample of numerical relativity simulations with different bi…
Construction of KAGRA: an Underground Gravitational Wave Observatory
T. Akutsu, M. Ando, S. Araki +222
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a m…
Numerical Relativity Simulations of Precessing Binary Neutron Star Mergers
Tim Dietrich, Sebastiano Bernuzzi, Bernd Bruegmann +2
We present the first set of numerical relativity simulations of binary neutron mergers that include spin precession effects and are evolved with multiple resolutions. Our simulatio…
Cancellation of divergences up to three loops in exceptional field theory
Guillaume Bossard, Axel Kleinschmidt
We consider the tetrahedral three-loop diagram in exceptional field theory evaluated as a scalar diagram for four external gravitons. At lowest order in momenta, this diagram…
Simplex-like Structures of Maximally Supersymmetric Scattering Amplitudes
Junjie Rao
We elaborate the two-fold simplex-like structures of tree amplitudes in planar maximally supersymmetric Yang-Mills (N=4 SYM), through its connection to a mathematical structure kno…
All-loop Mondrian Diagrammatics and 4-particle Amplituhedron
Yang An, Yi Li, Zhinan Li +1
Based on 1712.09990 which handles the 4-particle amplituhedron at 3-loop, we have found an extremely simple pattern, yet far more non-trivial than one might naturally expect: the a…
4-particle Amplituhedron at 3-loop and its Mondrian Diagrammatic Implication
Junjie Rao
This article provides a direct calculation of the 4-particle amplituhedron at 3-loop order, by introducing a set of practical tricks. After delicately rearranging each piece of thi…
Low significance of evidence for black hole echoes in gravitational wave data
Julian Westerweck, Alex B. Nielsen, Ofek Fischer-Birnholtz +6
Recent detections of merging black holes allow observational tests of the nature of these objects. In some proposed models, non-trivial structure at or near the black hole horizon…
Frame- and Metric-like Higher-Spin Fermions
Rakibur Rahman
Conventional descriptions of higher-spin fermionic gauge fields appear in two varieties: the Aragone-Deser-Vasiliev frame-like formulation and the Fang-Fronsdal metric-like formula…
Parameterized tests of the strong-field dynamics of general relativity using gravitational wave signals from coalescing binary black holes: Fast likelihood calculations and sensitivity of the method
