LION :Laser Interferometer On the mooN
Pau Amaro-Seoane, Lea Bischof, Jonathan J. Carter +2
Gravitational wave astronomy has now left its infancy and has become an important tool for probing the most violent phenomena in our universe. The LIGO/Virgo-KAGRA collaboration op…
SWIGLAL: Python and Octave interfaces to the LALSuite gravitational-wave data analysis libraries
Karl Wette
The LALSuite data analysis libraries, written in C, implement key routines critical to the successful detection of gravitational waves, such as the template waveforms describing th…
Propagation of polarized gravitational waves
Lars Andersson, Jérémie Joudioux, Marius A. Oancea +1
The propagation of high-frequency gravitational waves can be analyzed using the geometrical optics approximation. In the case of large but finite frequencies, the geometrical optic…
Sourcing curvature modes with entropy perturbations in non-singular bouncing cosmologies
Anna Ijjas, Roman Kolevatov
The observed temperature fluctuations in the cosmic microwave background can be traced back to primordial curvature modes that are sourced by adiabatic and/or entropic matter pertu…
Frequentist versus Bayesian analyses: Cross-correlation as an (approximate) sufficient statistic for LIGO-Virgo stochastic background searches
Andrew Matas, Joseph D. Romano
Sufficient statistics are combinations of data in terms of which the likelihood function can be rewritten without loss of information. Depending on the data volume reduction, the u…
Convergence of hydrodynamic modes: insights from kinetic theory and holography
Michal P. Heller, Alexandre Serantes, Michał Spaliński +2
We study the mechanisms setting the radius of convergence of hydrodynamic dispersion relations in kinetic theory in the relaxation time approximation. This introduces a qualitative…
A low-mass binary neutron star: long-term ejecta evolution and kilonovae with weak blue emission
Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata +2
We study the long-term evolution of ejecta formed in a binary neutron star (BNS) merger that results in a long-lived remnant NS by performing a hydrodynamics simulation with the ou…
Diving below the spin-down limit: Constraints on gravitational waves from the energetic young pulsar PSR J0537-6910
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1589
We present a search for continuous gravitational-wave signals from the young, energetic X-ray pulsar PSR J0537-6910 using data from the second and third observing runs of LIGO and…
Helicity, Spin, and Infra-zilch of Light: a Lorentz Covariant Formulation
Sajad Aghapour, Lars Andersson, Kjell Rosquist
In this paper, a novel conserved Lorentz covariant tensor, termed the helicity tensor, is introduced in Maxwell theory. The conservation of the helicity tensor expresses the conser…
All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369
Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…
A worldsheet for Kerr
Alfredo Guevara, Ben Maybee, Alexander Ochirov +2
We show that the Newman-Janis shift property of the exact Kerr solution can be interpreted in terms of a worldsheet effective action. This holds both in gravity, and for the single…
Higher spins from exotic dualisations
Nicolas Boulanger, Victor Lekeu
At the free level, a given massless field can be described by an infinite number of different potentials related to each other by dualities. In terms of Young tableaux, dualities r…
Correlation functions and quantum measures of descendant states
Enrico M. Brehm, Matteo Broccoli
We discuss a computer implementation of a recursive formula to calculate correlation functions of descendant states in two-dimensional CFT. This allows us to obtain any -point f…
Dynamical descalarization in binary black hole mergers
Hector O. Silva, Helvi Witek, Matthew Elley +1
Scalar fields coupled to the Gauss-Bonnet invariant can undergo a tachyonic instability, leading to spontaneous scalarization of black holes. Studies of this effect have so far bee…
Elliptic modular graph forms I: Identities and generating series
Eric D'Hoker, Axel Kleinschmidt, Oliver Schlotterer
Elliptic modular graph functions and forms (eMGFs) are defined for arbitrary graphs as natural generalizations of modular graph functions and forms obtained by including the charac…
Gmunu: Paralleled, grid-adaptive, general-relativistic magnetohydrodynamics in curvilinear geometries in dynamical spacetimes
Patrick Chi-Kit Cheong, Alan Tsz-Lok Lam, Harry Ho-Yin Ng +1
We present an update of the General-relativistic multigrid numerical (Gmunu) code, a parallelized, multi-dimensional curvilinear, general relativistic magnetohydrodynamics code wit…
Up-down instability of binary black holes in numerical relativity
Vijay Varma, Matthew Mould, Davide Gerosa +3
Binary black holes with spins that are aligned with the orbital angular momentum do not precess. However, post-Newtonian calculations predict that "up-down" binaries, in which the…
Plasma-photon interaction in curved spacetime I: formalism and quasibound states around nonspinning black holes
Enrico Cannizzaro, Andrea Caputo, Laura Sberna +1
We investigate the linear dynamics of an electromagnetic field propagating in curved spacetime in the presence of plasma. The dynamical equations are generically more involved and…
Quantum Circuit Complexity of Primordial Perturbations
Jean-Luc Lehners, Jerome Quintin
We study the quantum circuit complexity of cosmological perturbations in different models of the early universe. A natural measure for the complexity of cosmological perturbations…
Deep learning for clustering of continuous gravitational wave candidates II: identification of low-SNR candidates
Banafsheh Beheshtipour, Maria Alessandra Papa
Broad searches for continuous gravitational wave signals rely on hierarchies of follow-up stages for candidates above a given significance threshold. An important step to simplify…
