Neutron stars in extended scalar-Gauss-Bonnet gravity: the richness of the solution spectrum
Kalin V. Staykov, Peter Y. Yordanov, Daniela D. Doneva +1
Neutron stars are natural laboratories for testing gravity in the strong field regime. That is why the full spectrum of neutron star solutions in different modified theories should…
Crystallized white dwarf stars in scalar-tensor gravity
Sofía Vidal, Aneta Wojnar, Laur Järv +1
We study the effects of massive scalar-tensor theories on the internal properties, crystallization, and cooling process of white dwarf stars that might potentially solve observatio…
3+1 non-linear evolution of Ricci-coupled scalar-Gauss-Bonnet gravity
Daniela D. Doneva, Llibert Aresté Saló, Stoytcho S. Yazadjiev
Scalar-Gauss-Bonnet (sGB) gravity with an additional coupling between the scalar field and the Ricci scalar exhibits very interesting properties related to black hole stability, ev…
Quasinormal Modes in Modified Gravity using Physics-Informed Neural Networks
Raimon Luna, Daniela D. Doneva, José A. Font +2
In this paper, we apply a novel approach based on physics-informed neural networks to the computation of quasinormal modes of black hole solutions in modified gravity. In particula…
Testing disformal non-circular deformation of Kerr black holes with LISA
Eugeny Babichev, Christos Charmousis, Daniela D. Doneva +2
There is strong observational evidence that almost every large galaxy has a supermassive black hole at its center. It is of fundamental importance to know whether such black holes…
LISA Definition Study Report
Monica Colpi, Karsten Danzmann, Martin Hewitson +108
The Laser Interferometer Space Antenna (LISA) is the first scientific endeavour to detect and study gravitational waves from space. LISA will survey the sky for Gravitational Waves…
