Journal Article
Thaalba, F., Franchini, N., Bezares, M., & Sotiriou, T. P. (2025). Dynamics of spherically symmetric black holes in scalar-Gauss-Bonnet gravity with a Ricci coupling. Physical Review D, 11(6), Article 064054. https://doi.org/10.1103/PhysRevD.111.064054

We study the dynamics of spherically symmetric black holes in scalar Gauss-Bonnet gravity with an additional coupling between the scalar field and the Ricci scalar using nonlinear simulations that employ excision. In this class of theories, black hol... Read More about Dynamics of spherically symmetric black holes in scalar-Gauss-Bonnet gravity with a Ricci coupling.

Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening (2024)
Journal Article
Cayuso, R., Kuntz, A., Bezares, M., & Barausse, E. (2025). Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening. Physical Review D, 110(10), Article 104071. https://doi.org/10.1103/physrevd.110.104071

We explore scalar radiation from neutron star-black hole binaries in scalar-tensor theories with kinetic screening (𝐾-essence). Using 3+1 numerical relativity simulations in the decoupling limit, we investigate scalar dipole and quadrupole radiation...

Large eddy simulations of magnetized mergers of black holes and neutron stars (2024)
Journal Article
Izquierdo, M. R., Bezares, M., Liebling, S., & Palenzuela, C. (2024). Large eddy simulations of magnetized mergers of black holes and neutron stars. Physical Review D, 110(8), Article 083017. https://doi.org/10.1103/PhysRevD.110.083017

The LIGO-Virgo-Kagra collaboration has observed gravitational waves consistent with the mergers of a black hole and a neutron star, namely GW200105 and GW200115, providing evidence for such cataclysmic events. Although no electromagnetic counterpart... Read More about Large eddy simulations of magnetized mergers of black holes and neutron stars.

Spherical collapse in scalar-Gauss-Bonnet gravity: Taming ill-posedness with a Ricci coupling (2024)
Journal Article
Thaalba, F., Bezares, M., Franchini, N., & Sotiriou, T. P. (2024). Spherical collapse in scalar-Gauss-Bonnet gravity: Taming ill-posedness with a Ricci coupling. Physical Review D, 109(4), L041503. https://doi.org/10.1103/physrevd.109.l041503

We study spherical collapse of a scalar cloud in scalar-Gauss-Bonnet gravity—a theory in which black holes can develop scalar hair if they are in a certain mass range. We show that an additional quadratic coupling of the scalar field to the Ricci sca... Read More about Spherical collapse in scalar-Gauss-Bonnet gravity: Taming ill-posedness with a Ricci coupling.
