Addressing the gravitational collapse of a massless scalar field with Physics-Informed Neural Networks
Antonio Ferrer-Sánchez, Nino Villanueva-Espinosa, Carlos Hernani Morales +4
The gravitational collapse of a massless scalar field remains a demanding benchmark for numerical methods in numerical relativity, as it exhibits critical behavior at the boundary…
Dynamics of gauged Q-balls in three spatial dimensions
Michael P. Kinach, Matthew W. Choptuik
We investigate the dynamics of gauged Q-balls using fully three-dimensional numerical simulations. We consider two different scenarios: first, the classical stability of gau…
Relativistic head-on collisions of gauged Q-balls
Michael P. Kinach, Matthew W. Choptuik
We investigate the collision dynamics of gauged Q-balls by performing high-resolution numerical simulations in axisymmetry. Focusing on the case of relativistic head-on coll…
Universality in the Critical Collapse of the Einstein-Maxwell System
Gray D. Reid, Matthew W. Choptuik
We report on critical phenomena in the gravitational collapse of the electromagnetic field in axisymmetry using cylindrical coordinates. We perform detailed numerical simulations o…
RCCZ4: A Reference Metric Approach to Z4
Gray D. Reid, Matthew W. Choptuik
The hyperbolic formulations of numerical relativity due to Baumgarte, Shapiro, Shibata & Nakamura (BSSN) and Nagy Ortiz & Reula (NOR), among others, achieve stability through the e…
Stability of Non-Minimally Coupled Topological-Defect Boson Stars
Gray D. Reid, Matthew W. Choptuik
As shown by Marunovic and Murkovic, non-minimal d-stars, composite structures consisting of a boson star and a global monopole non-minimally coupled to the general relativistic fie…
