More hints of Planet Nine Nat. Astron. (IF 14.1) Pub Date : 2024-05-17 Luca Maltagliati
One of the most debated issues in Solar System studies of the last decade is whether there is a massive body hidden beyond the orbit of Neptune, known as ‘Planet Nine’ (P9). Invisible to direct observations so far, its presence has been hinted at by its effects on the dynamics of the Trans-Neptunian Objects (TNO) population, and many works have been published to support or disprove the significance

Optical properties of germania and titania at 1064 nm and at 1550 nm Classical Quant. Grav.

One of the main noise sources in current gravitational-wave detectors is the thermal noise of the high-reflectivity coatings on the main interferometer optics. Coating thermal noise is dominated by the mechanical loss of the high-refractive index material within the coating stacks, mixed with . For upgrades to room-temperature detectors, a mixture of and is an interesting alternative candidate coating

De Sitter-like configurations with asymptotic quintessence environment Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-16 Roberto Giambò and Orlando Luongo
We examine a spherically-symmetric class of spacetimes carrying vacuum energy, while considering the influence of an external dark energy environment represented by a non-dynamical quintessence field. Our investigation focuses on a specific set of solutions affected by this field, leading to distinct kinds of spacetime deformations, resulting in regular, singular, and wormhole solutions. We thoroughly

Magnetism in massive stars from mergers Nat. Astron. (IF 14.1) Pub Date : 2024-05-16 Bishwanath Gaire
Magnetic fields in stars are mass dependent. Lower-mass stars like the Sun sustain a magnetic field, but only about 7% of the massive stars (with eight or more solar masses) have large-scale surface magnetic fields. The origin of such magnetic fields is unclear. Abigail Frost and colleagues investigate a binary system of two massive stars (HD 148937) using interferometric and spectroscopic methods

Cosserat elasticity as the weak-field limit of Einstein-Cartan relativity Phys. Rev. D (IF 5.0) Pub Date : 2024-05-16 Matthew Maitra, Jeroen Tromp
The weak-field limit of Einstein-Cartan (EC) relativity is studied. The equations of EC theory are rewritten such that they formally resemble those of Einstein general relativity (EGR); this allows ideas from post-Newtonian theory to be imported without essential change. The equations of motion are then written both at first post-Newtonian (1PN) order and at 1.5PN order. EC theory’s 1PN equations of

Suppression of spacetime singularities in quantum gravity Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-15 Johanna N Borissova
We investigate the requirement of suppressing spacetime geometries with a curvature singularity via destructive interference in the Lorentzian gravitational path integral as a constraint on the microscopic action for gravity. Based on simple examples of static spherically symmetric spacetimes, we demonstrate that complete singularity suppression in the path integral stipulates that the action for gravity

Cosmography with next-generation gravitational wave detectors Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-14 Hsin-Yu Chen, Jose María Ezquiaga and Ish Gupta
Advancements in cosmology through next-generation (XG) ground-based gravitational wave (GW) observatories will bring in a paradigm shift. We explore the pivotal role that GW standard sirens will play in inferring cosmological parameters with XG observatories, not only achieving exquisite precision but also opening up unprecedented redshifts. We examine the merits and the systematic biases involved

A trick for calculating surface gravities of Killing horizons Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-14 Jinbo Yang
We propose a trick for calculating the surface gravity of the Killing horizon, especially for cases of rotating black holes. By choosing nice slices, the surface gravity and angular velocities can be directly read from relevant components of the inverse metric. We give several cases to show how to apply the trick step by step.

Comment on ‘Index-free heat kernel coefficients’ Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-14 S A Franchino-Viñas
The article by van de Ven (1998 Class.

In this manuscript, we point out two errors and ambiguities in the coefficient, which may also affect the higher-order ones.

Neural network time-series classifiers for gravitational-wave searches in single-detector periods Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-13 A Trovato, E Chassande-Mottin, M Bejger, R Flamary and N Courty
The search for gravitational-wave (GW) signals is limited by non-Gaussian transient noises that mimic astrophysical signals. Temporal coincidence between two or more detectors is used to mitigate contamination by these instrumental glitches. However, when a single detector is in operation, coincidence is impossible, and other strategies have to be used. We explore the possibility of using neural network

Quick recipes for gravitational-wave selection effects Classical Quant. Grav. (IF 3.5) Pub Date : 2024-05-13 Davide Gerosa and Malvina Bellotti
Accurate modeling of selection effects is a key ingredient to the success of gravitational-wave astronomy. The detection probability plays a crucial role in both statistical population studies, where it enters the hierarchical Bayesian likelihood, and astrophysical modeling, where it is used to convert predictions from population-synthesis codes into observable distributions. We review the most commonly

Partially celestial states and their scattering amplitudes Phys. Rev. D (IF 5.0) Pub Date : 2024-05-14 Csaba Csáki, Ofri Telem, John Terning
We study representations of the Poincaré group that have a privileged transformation law along a p-dimensional hyperplane, and uncover their associated spinor-helicity variables in D spacetime dimensions. Our novel representations generalize the recently introduced celestial states and transform as conformal primaries of SO(p,1), the symmetry group of the p-hyperplane. We will refer to our generalized
