Ultra-High-Energy Particle Production in Binary Mergers Endowed with Magnetic Fields
Carlos H. Coimbra-Araujo, Rita C. Anjos, Jonas P. Pereira +1
We study the production of ultra-high-energy particles via the Bañados--Silk--West (BSW) mechanism in the pre-merger phase of binary systems detected by LIGO-Virgo-KAGRA. By solvin…
Binary coalescences as sources of Ultra-High Energy Cosmic Rays
Jonas P. Pereira, Carlos H. Coimbra-Araújo, Rita C. dos Anjos +1
Binary coalescences are known sources of gravitational waves (GWs) and they encompass combinations of black holes (BHs) and neutron stars (NSs). Here we show that when BHs are embe…
A connection between Lyapunov exponents and sensitive dependence on parameters of chaotic systems
Samuel Willian Schwertner Costiche, Carlos Henrique Coimbra-Araújo, Rodrigo André Schulz
The sensitive dependence of chaos on parameters is a topic of great interest in the study of integrability and stability of dynamical systems. Previous work has proposed ways to id…
