Testing the limits of scalar-Gauss-Bonnet gravity through nonlinear evolutions of spin-induced scalarization
Daniela D. Doneva, Llibert Aresté Saló, Katy Clough +2
Quadratic theories of gravity with second order equations of motion provide an interesting model for testing deviations from general relativity in the strong gravity regime. Howeve…
Distinctive Features of Hairy Black Holes in Teleparallel Gauss-Bonnet Gravity
Sebastian Bahamonde, Daniela D. Doneva, Ludovic Ducobu +2
We examine the teleparallel formulation of non-minimally coupled scalar Einstein-Gauss-Bonnet gravity. In the teleparallel formulation, gravity is described by torsion instead of c…
Polarized image of equatorial emission in horizonless spacetimes: naked singularities
Valentin Deliyski, Galin Gyulchev, Petya Nedkova +1
We study the linear polarization from the accretion disk around weakly and strongly naked Janis-Newman-Winicour singularities. We consider an analytical toy model of thin magnetize…
Differentially rotating scalarized neutron stars with realistic post-merger profile
Kalin V. Staykov, Daniela D. Doneva, Lavinia Heisenberg +2
The merger remnant of a binary neutron star coalescence is initially strongly differentially rotating. Some properties of these remnants can be accurately modeled through building…
Dynamical Scalarization during Neutron Star Mergers in scalar-Gauss-Bonnet Theory
Hao-Jui Kuan, Alan Tsz-Lok Lam, Daniela D. Doneva +3
In certain classes of the scalar-Gauss-Bonnet theory strong spacetime curvature in the vicinity of neutron stars and black holes can spontaneously trigger scalarization in the comp…
