PhenomXO4a: a phenomenological gravitational-wave model for precessing black-hole binaries with higher multipoles and asymmetries
Jonathan E. Thompson, Eleanor Hamilton, Lionel London +4
In this work we introduce PhenomXO4a, the first phenomenological, frequency-domain gravitational waveform model to incorporate multipole asymmetries and precession angles tuned to…
Designing Gram-Scale Resonators for Precision Inertial Sensors
Jonathan J. Carter, Pascal Birckigt, Oliver Gerberding +1
Recent advances in glass fabrication technology have allowed for the development of high-precision inertial sensors in devices weighing in the order of grams. Gram-scale inertial s…
Linear vs. nonlinear modeling of black hole ringdowns
Yi Qiu, Xisco Jiménez Forteza, Pierre Mourier
The ringdown (RD) phase of gravitational waves is of prime interest for testing general relativity (GR). The modelling of the linear quasi-normal modes (QNMs) within the Kerr spect…
Magnetar-powered Neutrinos and Magnetic Moment Signatures at IceCube
Ting Cheng, Hao-Jui Kuan, Ying-Ying Li +1
The IceCube collaboration pioneered the detection of neutrino events and the identification of astrophysical sources of high-energy neutrinos. In this s…
Do black holes remember what they are made of?
Harshraj Bandyopadhyay, David Radice, Aviral Prakash +4
We study the ringdown signal of black holes formed in prompt-collapse binary neutron star mergers. We analyze data from numerical relativity simulations. We show that the $(\e…
Breaking black-hole uniqueness at supermassive scales
Astrid Eichhorn, Pedro G. S. Fernandes, Aaron Held +1
In general relativity, all vacuum black holes are described by the Kerr solution. Beyond general relativity, there is a prevailing expectation that deviations from the Kerr solutio…
Spectral method for metric perturbations of black holes: Kerr background case in general relativity
Adrian Ka-Wai Chung, Pratik Wagle, Nicolas Yunes
We present a novel approach, (METRICS), to calculate the gravitational metric perturbations and the quasinormal-mode frequenci…
Extreme mass-ratio inspirals in ultra-light dark matter
Francisco Duque, Caio F. B. Macedo, Rodrigo Vicente +1
Previous works have argued that future gravitational-wave detectors will be able to probe the properties of astrophysical environments where binary coalesce, including accretion di…
Emergent Time and Time Travel in Quantum Physics
Ana Alonso-Serrano, Sebastian Schuster, Matt Visser
Entertaining the possibility of time travel will invariably challenge dearly held concepts of fundamental physics. It becomes relatively easy to construct multiple logical contradi…
Massive black hole binaries in LISA: constraining cosmological parameters at high redshifts
Alberto Mangiagli, Chiara Caprini, Sylvain Marsat +3
One of the scientific objectives of the Laser Interferometer Space Antenna (LISA) is to probe the expansion of the Universe using gravitational wave observations. Indeed, as gravit…
Neutron stars more compact than black holes as a probe of strong-field gravity
Shoulong Li, H. Lü, Yong Gao +3
Probing gravity in its strongest regime is a central goal of modern physics, as the nature of the most compact objects reflects fundamental aspects of Einstein's theory of general…
Glued lattices are better quantizers than
Erik Agrell, Daniel Pook-Kolb, Bruce Allen
40 years ago, Conway and Sloane proposed using the highly symmetrical Coxeter-Todd lattice for quantization, and estimated its second moment. Since then, all published lis…
XKN: a Semi-analytic Framework for the Modelling of Kilonovae
Giacomo Ricigliano, Albino Perego, Ssohrab Borhanian +4
After GW170817, kilonovae have become of great interest for the astronomical, astrophysics and nuclear physics communities, due to their potential in revealing key information on t…
Phenomenological gravitational waveform model of binary black holes incorporating horizon fluxes
Samanwaya Mukherjee, Khun Sang Phukon, Sayak Datta +1
Subjected to the tidal field of its companion, each component of a coalescing black hole binary suffers a slow change in its mass (tidal heating) and spin (tidal torquing) during t…
New gravitational waveform model for precessing binary neutron stars with double-spin effects
Marta Colleoni, Felip A. Ramis Vidal, Nathan K. Johnson-McDaniel +3
We present two new frequency-domain gravitational waveform models for the analysis of signals emitted by binary neutron star coalescences: IMRPhenomXAS_NRTidalv2 and IMRPhenomXP_NR…
Gravitational wave populations and cosmology with neural posterior estimation
Konstantin Leyde, Stephen R. Green, Alexandre Toubiana +1
We apply neural posterior estimation for fast-and-accurate hierarchical Bayesian inference of gravitational wave populations. We use a normalizing flow to estimate directly the pop…
Efficient representations of upper limits and confidence intervals for experimental data
Vladimir Dergachev
Upper limits and confidence intervals are a convenient way to present experimental results. With modern experiments producing more and more data, it is often necessary to reduce th…
Charged rotating BTZ solution revisited: New coordinates and algebraic classifications
Hideki Maeda, Jiri Podolsky
We revisit the charged rotating Bañados-Teitelboim-Zanelli (BTZ) solution in the three-dimensional Einstein-Maxwell- system. After the erroneous announcement of its discovery at…
New and Robust Gravitational-Waveform Model for High-Mass-Ratio Binary Neutron Star Systems with Dynamical Tidal Effects
Adrian Abac, Tim Dietrich, Alessandra Buonanno +2
For the analysis of gravitational-wave signals, fast and accurate gravitational-waveform models are required. These enable us to obtain information on the system properties from co…
Integral of depth zero to three basis of Modular Graph Functions
Mehregan Doroudiani
Modular Graph Functions (MGFs) are SL(2,)-invariant functions that emerge in the study of the low-energy expansion of the one-loop closed string amplitude. To find the…
Effect of double spin-precession and higher harmonics on spin-induced quadrupole moment measurements
Divyajyoti, N. V. Krishnendu, Muhammed Saleem +4
We investigate the prospect of performing a null test of binary black hole (BBH) nature using spin-induced quadrupole moment (SIQM) measurements. This is achieved by constraining a…
