Lensing and shadow of a black hole surrounded by a heavy accretion disk
Pedro V. P. Cunha, Nelson A. Eiró, Carlos A. R. Herdeiro +1
We consider a static, axially symmetric spacetime describing the superposition of a Schwarzschild black hole (BH) with a thin and heavy accretion disk. The BH-disk configuration is…
Search for Eccentric Binary Neutron Star Mergers in the first and second observing runs of Advanced LIGO
Alexander H. Nitz, Amber Lenon, Duncan A. Brown
We present a search for gravitational waves from merging binary neutron stars which have non-negligible eccentricity as they enter the LIGO observing band. We use the public Advanc…
Excited hairy black holes: dynamical construction and level transitions
Pablo Bosch, Stephen R. Green, Luis Lehner +1
We study the dynamics of unstable Reissner-Nordström anti-de Sitter black holes under charged scalar field perturbations in spherical symmetry. We unravel their general behavior an…
Hydrodynamic simulations unravel the progenitor-supernova-remnant connection in SN 1987A
S. Orlando, M. Ono, S. Nagataki +8
(Abridged) We aim at linking the dynamical and radiative properties of the remnant of SN 1987A to the geometrical and physical characteristics of the parent aspherical SN explosion…
The next decade of black hole spectroscopy
Miriam Cabero, Julian Westerweck, Collin D. Capano +3
Gravitational wave observations of the ringdown of the remnant black hole in a binary black hole coalescence provide a unique opportunity of confronting the black hole no-hair theo…
Matter Mixing in Aspherical Core-collapse Supernovae: Three-dimensional Simulations with Single Star and Binary Merger Progenitor Models for SN 1987A
Masaomi Ono, Shigehiro Nagataki, Gilles Ferrand +5
We perform three-dimensional hydrodynamic simulations of aspherical core-collapse supernovae focusing on the matter mixing in SN 1987A. The impacts of four progenitor (pre-supernov…
Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1245
Advanced LIGO and Advanced Virgo are actively monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this pape…
The correlation function of (1,1) and (2,2) supersymmetric theories with deformation
Song He, Jia-Rui Sun, Yuan Sun
In the paper, based on recent studies on deformation of 2D field theory with supersymmetry, we investigate the deformed correlation functions in and…
Amplitude recursions with an extra marked point
Johannes Broedel, Andre Kaderli
The recursive calculation of Selberg integrals by Aomoto and Terasoma using the Knizhnik-Zamolodchikov equation and the Drinfeld associator makes use of an auxiliary point and faci…
Gravitational-Wave Constraints on an Effective Field-Theory Extension of General Relativity
Noah Sennett, Richard Brito, Alessandra Buonanno +2
Gravitational-wave observations of coalescing binary systems allow for novel tests of the strong-field regime of gravity. Using data from the Gravitational Wave Open Science Center…
Dissipation in extreme-mass ratio binaries with a spinning secondary
Sarp Akcay, Sam R. Dolan, Chris Kavanagh +3
We present the gravitational-wave flux balance law in an extreme mass-ratio binary with a spinning secondary. This law relates the flux of energy (angular momentum) radiated to nul…
A note on the Drinfeld associator for genus-zero superstring amplitudes in twisted de Rham theory
Andre Kaderli
The string corrections of tree-level open-string amplitudes can be described by Selberg integrals satisfying a Knizhnik-Zamolodchikov (KZ) equation. This allows for a recursion of…
Field Theories on Null Manifolds
Arjun Bagchi, Rudranil Basu, Aditya Mehra +1
We argue that generic field theories defined on null manifolds should have an emergent BMS or conformal Carrollian structure. We then focus on a simple interacting conformal Carrol…
From spin chains to real-time thermal field theory using tensor networks
Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
One of the most interesting directions in theoretical high-energy and condensed-matter physics is understanding dynamical properties of collective states of quantum field theories.…
Newton-Hooke/Carrollian expansions of (A)dS and Chern-Simons gravity
Joaquim Gomis, Axel Kleinschmidt, Jakob Palmkvist +1
We construct finite- and infinite-dimensional non-relativistic extensions of the Newton-Hooke and Carroll (A)dS algebras using the algebra expansion method, starting from the (anti…
On average properties of inhomogeneous fluids in general relativity III: general fluid cosmologies
Thomas Buchert, Pierre Mourier, Xavier Roy
We investigate effective equations governing the volume expansion of spatially averaged portions of inhomogeneous cosmologies in spacetimes filled with an arbitrary fluid. This wor…
Astrometric Effects of Gravitational Wave Backgrounds with non-Luminal Propagation Speeds
Deyan P. Mihaylov, Christopher J. Moore, Jonathan Gair +2
A passing gravitational wave causes a deflection in the apparent astrometric positions of distant stars. The effect of the speed of the gravitational wave on this astrometric shift…
Circumbinary exoplanets and brown dwarfs with the Laser Interferometer Space Antenna
Camilla Danielski, Valeriya Korol, Nicola Tamanini +1
We explore the prospects for the detection of giant circumbinary exoplanets and brown dwarfs (BDs) orbiting Galactic double white dwarfs binaries (DWDs) with the Laser Interferomet…
Robust and resource-efficient microwave near-field entangling Be gate
G. Zarantonello, H. Hahn, J. Morgner +5
Microwave trapped-ion quantum logic gates avoid spontaneous emission as a fundamental source of decoherence. However, microwave two-qubit gates are still slower than laser-induced…
Axial gravity and anomalies of fermions
Fiorenzo Bastianelli, Matteo Broccoli
We consider a Dirac fermion in a metric-axial-tensor (MAT) background. By regulating it with Pauli-Villars fields we analyze and compute its full anomaly structure. Appropriate lim…
Kaluza-Klein Spectrometry for Supergravity
Emanuel Malek, Henning Samtleben
Exceptional field theories yield duality covariant formulations of supergravity. We show that they provide a highly efficient tool to compute the Kaluza-Klein mass spectra associat…
