New black hole solutions with a dynamical traceless nonmetricity tensor in Metric-Affine Gravity

Sebastian Bahamonde et al.

Summary: In the framework of Metric-Affine Gravity, the correspondence between the Einstein tensor and the energy-momentum tensor of matter is extended towards a post-Riemannian description in terms of torsion and nonmetricity fields. The dynamical role of the traceless part of the nonmetricity tensor and its connection with shears are investigated, resulting in a new black hole solution with shear charges. The extension in the presence of dynamical torsion and Weyl vector leads to the broadest family of black hole solutions with spin, dilation, and shear charges in Metric-Affine Gravity so far.

Teleparallel gravity: from theory to cosmology

Sebastian Bahamonde et al.

Summary: In this Review, the development of teleparallel gravity as a gauge theory of translations is comprehensively introduced. The construction of consistent teleparallel theories that respect physical conditions such as local Lorentz invariance is described. Various modified teleparallel theories of gravity are discussed and connected into general classes of covariant gravitational theories. The cosmological consequences and observational implications of teleparallel gravity are also explored, along with the application of machine learning to gravity research.

Where and why does Einstein-scalar-Gauss-Bonnet theory break down?

K. R. Abhishek Hegade et al.

Summary: We present a systematic exploration of the loss of predictivity in Einstein-scalar-Gauss-Bonnet (ESGB) gravity in spherical symmetry. Using a gauge covariant method, we show that the breakdown of hyperbolicity in the theory is related to strong geodesic focusing, rather than the violation of the null convergence condition. Numerical studies on two specific ESGB gravity theories reveal that they remain predictive for a small range of Gauss-Bonnet couplings, indicating the need for fine-tuning of initial data for the existence of scalarized black holes. Our results cast doubt on the realistic realization of scalarized black hole solutions in nature even if ESGB gravity is the correct gravitational description.

Perturbations in non-flat cosmology for f(T) gravity

Sebastian Bahamonde et al.

Summary: This study focuses on the cosmological perturbation theory in f(T) gravity, which is a simple extension of the teleparallel equivalent of general relativity. The authors examine the possibility of a non-flat FLRW background solution and perform perturbations for different spatial geometries.

Well-Posedness of the Four-Derivative Scalar-Tensor Theory of Gravity in Singularity Avoiding Coordinates

Llibert Areste Salo et al.

Summary: This study demonstrates that the most general scalar-tensor theory of gravity with four derivatives in 3+1 dimensions can be well-posed in a modified version of the CCZ4 formulation of the Einstein equations in singularity-avoiding coordinates.

Compact objects of spherical symmetry in beyond Horndeski theories

A. Bakopoulos et al.

Summary: We analyze the shift symmetry of Horndeski theories in a static and spherically symmetric spacetime. By introducing auxiliary functions, we simplify the field equations. We find that assuming parity symmetry allows for direct integrability and multiple families of black-hole solutions. In the absence of parity symmetry, we propose a general method to integrate the field equations by choosing a specific form for one coupling function and an auxiliary quantity. This method leads to asymptotically flat and AdS black hole solutions with different properties. We also discuss disformal transformations as a means of obtaining wormhole and black hole solutions in different theories.

Gravitational wave birefringence in spatially curved teleparallel cosmology

Manuel Hohmann et al.

Summary: This study investigates tensor perturbations around the most general cosmologically symmetric backgrounds in a class of teleparallel gravity theories known as New General Relativity. The findings reveal the existence of gravitational wave birefringence and dispersion in these theories for a particular class of cosmological background geometries. The strength of this effect is determined by the spatial curvature of the cosmological background and the deviation parameter from General Relativity. The possibility of observing this effect in gravitational wave experiments is discussed.

Testing Born-Infeld f (T) teleparallel gravity through Sgr A* observations

Kimet Jusufi et al.

Summary: We use observational data to constrain a black hole solution of extended teleparallel gravity models based on the S2 star orbiting the Galactic Center. We construct the shadow images of the Sgr A* black hole and find that the shadow radius increases with the parameter alpha. The observables, such as the deflection angle and angular diameter, are close to the Schwarzschild case. However, the electromagnetic intensity observed in the shadow images is smaller compared to General Relativity (GR), indicating differences in the Born-Infeld f(T) gravity.

Summary: In this paper, we study various forms of diagonal tetrad solutions in f(T) gravity with specific symmetries. We find that constant torsion scalar is required for all possible horizon topologies, regardless of spherical, hyperbolic, or planar. We provide a full classification of vacuum static solutions and discuss the addition of time-dependence. Furthermore, we discover that the presence of matter is necessary for non-trivial solutions in the case of planar symmetry.

Radial perturbations of scalar-Gauss-Bonnet black holes beyond spontaneous scalarization

Jose Luis Blazquez-Salcedo et al.

Summary: In scalar-Gauss-Bonnet gravity, black holes can acquire scalar hair through the phenomenon of spontaneous scalarization, while leaving the weak field regime of the theory practically unaltered. A new type of nonlinear scalarization beyond the standard one has been shown to be possible by allowing for a different form of coupling between the scalar field and the Gauss-Bonnet invariant. This paper studies the stability of these scalarized black hole phases and demonstrates that one of them can be stable and hyperbolic for sufficiently large black hole masses, making them viable astrophysical candidates.

Summary: A recently study shows that a scalar field coupled to the Gauss-Bonnet invariant can experience a spin-induced linear tachyonic instability near a Kerr black hole, only when the dimensionless spin j is greater than or equal to 0.5. Results demonstrate that black hole solutions do have scalar hair once the spin-induced instability threshold is exceeded, supporting the idea of spin-induced black hole scalarization.

Eikonal quasinormal modes of black holes beyond general relativity. III. Scalar Gauss-Bonnet gravity

Albert Bryant et al.

Summary: In a recent series of papers, the authors have demonstrated the use of the eikonal/geometrical optics approximation to analytically calculate the fundamental quasinormal mode frequencies associated with coupled systems of wave equations. They focused on the quasinormal modes of nonrotating black holes in scalar Gauss-Bonnet gravity, showing deviations from general relativistic results at quadratic order in the coupling constant. The small-coupling expansion allowed for the identification of the quasinormal modes of the scalar-tensor coupled system of wave equations, with analytical frequencies agreeing with numerical results within an error of O(10%) for small coupling constants.
