Cut-and-paste for impulsive gravitational waves with : The mathematical analysis
Clemens Sämann, Benedict Schinnerl, Roland Steinbauer +1
Impulsive gravitational waves are theoretical models of short but violent bursts of gravitational radiation. They are commonly described by two distinct spacetime metrics, one of l…
Well-posed non-vacuum solutions in Robinson--Trautman geometry
T. Tahamtan, D. Flores-Alfonso, O. Svitek
We study nonlinear matter models compatible with radiative Robinson--Trautman spacetimes and analyze their stability and well-posedness. The results lead us to formulate a conjectu…
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…
Algebraic classification of 2+1 geometries: a new approach
Matus Papajcik, Jiri Podolsky
We present a convenient method of algebraic classification of 2+1 spacetimes into the types I, II, D, III, N and O, without using any field equations. It is based on the 2+1 analog…
A novel classification method of 2+1 spacetimes based on the Cotton scalars
Jiri Podolsky, Matus Papajcik
A new effective approach to the algebraic classification of geometries in 2+1 gravity is presented. It uses five real Cotton scalars of distinct boost weights, which are 3D a…
Effective-one-body waveforms for extreme-mass-ratio binaries: Consistency with second-order gravitational self-force quasicircular results and extension to nonprecessing spins and eccentricity
Angelica Albertini, Rossella Gamba, Alessandro Nagar +1
We present a first complete implementation of an effective-one-body (EOB) model for extreme-mass-ratio inspirals (EMRIs) that incorporates aligned spins (on both the primary and th…
Torsion at different scales: from materials to the Universe
Nick E. Mavromatos, Pablo Pais, Alfredo Iorio
The concept of torsion in geometry, although known for a long time, has not gained considerable attention by the physics community until relatively recently, due to its diverse and…
Light Deflection in Plasma in the Hartle-Thorne Metric and in Other Axisymmetric Spacetimes with a Quadrupole Moment
Barbora Bezdekova, Jiri Bicak
The light propagation in plasma medium around stationary gravitating objects is studied in the geometrical optics limit. Static metrics with quadrupole moments are considered, howe…
Dynamics of redshift/blueshift during free fall under the Schwarzschild horizon
H. V. Ovcharenko, O. B. Zaslavskii
We consider a free-falling observer who crosses the event horizon in the Schwarzschild background. In the course of this fall, he/she can receive signals from an object (like a sta…
Plebanśki-Demiański à la Ehlers-Harrison: Exact Rotating and Accelerating Type I Black Holes
José Barrientos, Adolfo Cisterna, Konstantinos Pallikaris
Recently, it was shown that type D black holes, encompassed in the large Plebanśki--Demiański (PD) family, exhibit a wide class of algebraically general generalizations via the app…
Solutions with pure radiation and gyratons in 3D massive gravity theories
Ercan Kilicarslan, Ivan Kolář
We find exact solutions of topologically massive gravity (TMG) and new massive gravity (NMG) in dimensions (3D) with an arbitrary cosmological constant, pure radiation, and…
Charging Kerr-Schild spacetimes in higher dimensions
Marcello Ortaggio, Aravindhan Srinivasan
We study higher dimensional charged Kerr-Schild (KS) spacetimes that can be constructed by a KS transformation of a vacuum solution with an arbitrary cosmological constant, and for…
Quadrupolar radiation in de Sitter: Displacement memory and Bondi metric
Geoffrey Compère, Sk Jahanur Hoque, Emine Şeyma Kutluk
We obtain the closed form expression for the metric perturbation around de Sitter spacetime generated by a matter source below Hubble scale both in generalized harmonic gauge and i…
Symmetric Teleparallel Gauss-Bonnet Gravity and its Extensions
Juan Manuel Armaleo, Sebastian Bahamonde, Georg Trenkler +1
General Teleparallel theories assume that curvature is vanishing in which case gravity can be solely represented by torsion and/or nonmetricity. Using differential form language, w…
Analytic solutions for the motion of spinning particles near spherically symmetric black holes and exotic compact objects
Vojtěch Witzany, Gabriel Andres Piovano
Rapidly rotating bodies moving in curved space-time experience the so-called spin-curvature force, which becomes important for the motion of compact objects in gravitational-wave i…
Infinite derivative gravity resolves nonscalar curvature singularities
Ivan Kolář, Tomáš Málek
We explicitly demonstrate that the nonlocal ghost-free ultraviolet modification of general relativity (GR) known as the infinite derivative gravity (IDG) resolves nonscalar curvatu…
Carrollian limit of quadratic gravity
Poula Tadros, Ivan Kolář
We study the Carrollian limit of the (general) quadratic gravity in four dimensions. We find that in order for the Carrollian theory to be a modification of the Carrollian limit of…
Propagators in AdS for higher-derivative and nonlocal gravity: Heat kernel approach
Ivan Kolář, Tomáš Málek
We present a new covariant method of construction of the (position space) propagators in the -dimensional (Euclidean) anti-de Sitter background for any gravitational theory with…
Quasinormal modes of black holes encircled by a gravitating thin disk
Che-Yu Chen, Petr Kotlařík
The ringdown phase of gravitational waves emitted by a perturbed black hole is described by a superposition of exponentially decaying sinusoidal modes, called quasinormal modes (QN…
Critical phenomena in the collapse of gravitational waves
Thomas W. Baumgarte, Bernd Brügmann, Daniela Cors +6
Fine-tuning generic but smooth spherically-symmetric initial data for general relativity to the threshold of dynamical black hole formation creates arbitrarily large curvatures, me…
Frenemies with Physicality: Manufacturing Manifold Metrics
Sebastian Schuster
Physicality has the bad habit of sneaking up on unsuspecting physicists. Unfortunately, it comes in multitudinous incarnations, which will not always make sense in a given situatio…
Thermodynamics as a tool for (quantum) gravitational dynamics
Ana Alonso-Serrano, Marek Liška
The thermodynamics of local causal horizons has been shown to imply gravitational dynamics. In this essay, we discuss the principles underlying this observation, and its significan…
Bañados-Silk-West effect with finite forces near different types of horizons: general classification of scenarios
H. V. Ovcharenko, O. B. Zaslavskii
If two particles move towards a black hole and collide in the vicinity of the horizon, under certain conditions their energy in the center of mass frame can grow unbound…
