Data-Driven Acceleration of Eccentricity Reduction for Binary Black Hole Simulations

Vittoria Tommasini, Nils L. Vu, Mark A. Scheel +1

Reducing orbital eccentricity in numerical relativity simulations of binary black holes is essential for producing astrophysically relevant gravitational wave models, as many of th…

GW250114 reveals black hole horizon signatures

Neil Lu, Sizheng Ma, Ornella J. Piccinni +2

The horizon of a black hole, the "surface of no return", is characterized by its rotation frequency and surface gravity . A striking signature is that any infalling object…

White dwarf structure in gravity: beyond the Chandrasekhar mass limit

Edson Otoniel, Juan M. Z. Pretel, Clésio E. Mota +3

In this work, we investigate the relativistic structure of white dwarfs (WDs) within the framework of modified gravity theory , which introduces a non-mi…

Incorporation of model accuracy in gravitational wave Bayesian inference

Charlie Hoy, Sarp Akcay, Jake Mac Uilliam +1

Inferring the properties of colliding black holes from gravitational-wave observations is subject to systematic errors arising from modelling uncertainties. Although the accuracy o…

Geodesic Model of HF QPOs Tested for Black Holes in Spacetimes Reflecting the Effect of Surrounding Dark Matter

Zdeněk Stuchlík, Jaroslav Vrba

Using the simple but robust model of a shell of dark matter (DM) around a Schwarzschild black hole (BH), represented by the mass ratio of the shell and BH , the shell extensi…

Supermassive black holes surrounded by dark matter modeled as anisotropic fluid: epicyclic oscillations and their fitting to observed QPOs

Zdeněk Stuchlík, Jaroslav Vrba

Recently introduced exact solution of the Einstein gravity coupled minimally to an anisotropic fluid representing dark matter can well represent supermassive black holes in galacti…

Inverse-Chirp Imprint of Gravitational Wave Signals in Scalar Tensor Theory

Chao-Qiang Geng, Hao-Jui Kuan, Ling-Wei Luo

The scalar tensor theory contains a coupling function connecting the quantities in the Jordan and Einstein frames, which is constrained to guarantee a transformation rule between f…

Wavefronts and Light Cones for Kerr Spacetimes

Francisco Frutos-Alfaro, Frank Grave, Thomas Mueller +1

We investigate the light propagation by means of simulations of wavefronts and light cones for Kerr spacetimes. Simulations of this kind give us a new insight to better understand…

Quintessence with Kaluza-Klein type couplings to matter and an isotropy-violating vector field

Mikjel Thorsrud

We study the dynamics of a scalar field with Kaluza-Klein type couplings to cold dark matter and an isotropy-violating vector field. The vector coupling, , has been stud…

New Equations for Gravitation with Riemann Tensor and 4-Index Energy-Momentum Tensors for Gravitation and Matter

Zahid Zakir

A generalized version of the Einstein equations in the 4-index form, containing the Riemann tensor linearly, is derived. It is shown, that the gravitational energy-momentum density…
