Nonlinear evolution in Galileon EFTs: Regularization and screening
Farid Thaalba, Aaron Held, Ramiro Cayuso +1
In a scalar effective field theory (EFT) with Galileon symmetry, we distinguish the strong-field expansion from the derivative expansion and study spherically symmetric classical n…
Scalar emission from binary neutron stars in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Thiago Assumpcao +2
We investigate the scalar emission from binary neutron stars in shift-symmetric scalar-tensor theories with kinetic screening (-essence), using 3+1 numerical simulations in the…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening
Ramiro Cayuso, Adrien Kuntz, Miguel Bezares +1
We explore scalar radiation from neutron star-black hole binaries in scalar-tensor theories with kinetic screening (-essence). Using 3+1 numerical relativity simulations in the…
Deep Learning solutions to singular ordinary differential equations: from special functions to spherical accretion
R. Cayuso, M. Herrero-Valea, E. Barausse
Singular regular points often arise in differential equations describing physical phenomena such as fluid dynamics, electromagnetism, and gravitation. Traditional numerical techniq…
Gravitational collapse in Quadratic Gravity
Ramiro Cayuso
This study explores the gravitational collapse of a massless scalar field within Quadratic Gravity treated as a dimension-four operator Effective Field Theory extension to General…
Modelling self-consistently beyond General Relativity
Ramiro Cayuso, Pau Figueras, Tiago França +1
The majority of extensions to General Relativity display mathematical pathologies (higher derivatives, character change in equations that can be classified within PDE theory, and e…
Nonlinear/non-iterative treatment of EFT-motivated gravity
Ramiro Cayuso, Luis Lehner
We study a higher derivative extension to General Relativity and present a fully nonlinear/non-perturbative treatment to construct initial data and study its dynamical behavior in…
Astrophysical jets from boosted compact objects
Ramiro Cayuso, Federico Carrasco, Barbara Sbarato +1
We perform full 3D numerical simulations of compact objects, such as black holes or neutron stars, boosted through an ambient force-free plasma that posses a uniform magnetization.…
