Orbital evolution of asymmetric binaries within accreting environments
Albert Radulea, Marcelo E. Rubio, Konstantinos Kritos +1
Extreme mass-ratio inspirals embedded in accretion disks provide a natural arena for studying the interplay between relativistic orbital dynamics and environmental effects. In this…
Constraint evolution in first-order viscous relativistic fluids
Delfina Fantini, Marcelo E. Rubio
Relativistic hydrodynamics provides a solid framework for evolving matter and energy in a wide variety of phenomena. Nevertheless, the inclusion of dissipative effects in realistic…
Bekenstein bounds in maximally symmetric nonlinear electrodynamics
Juan Manuel Diaz, Marcelo E. Rubio
We explore dynamical features of the maximally symmetric nonlinear extension of classical electromagnetism, recently proposed in the literature as ``ModMax'' electrodynamics. This…
Fixing the dynamical evolution of self-interacting vector fields
Marcelo E. Rubio, Guillermo Lara, Miguel Bezares +2
Numerical simulations of the Cauchy problem for self-interacting massive vector fields often face instabilities and apparent pathologies. We explicitly demonstrate that these issue…
