Self-force on a static scalar charge in traversable wormholes
Jerome P. Mecca, Ian Vega
The self-force acting on a charged particle is sensitive to the global structure of curved spacetime and can serve as a probe of geometry beyond local curvature. We compute the sta…
Waveform degeneracy of binary systems and Lagrange three-body systems
Carlos Jaimel Doctolero, Ian Vega
A particular solution to the three-body problem is the circular Lagrange three-body system, where the masses move in circular orbits such that they always constitute an equilateral…
Extreme-mass ratio inspirals in Schwarzschild - de Sitter spacetime I: Weak-field orbits
John Adrian N. Villanueva, Ian Vega
The inspiral of a compact object into a black hole is a key source of low - frequency gravitational waves for future space-based detectors like LISA. While models of this process h…
Analytic force-free jet from disk-fed rotating black holes
Luis Villarin, Ian Vega
We present a new analytic model of a force-free electromagnetic jet launched from a disk-fed rotating black hole. The jet solution is force-free to first order in the black hole sp…
Imprints of a galactic environment on TDEs: Suppressed peaks, shallower decays and late-time rebrightening episodes
Cedric Oña, Sean Fortuna, Ian Vega
Classic models of tidal disruption events (TDEs), employing a purely Keplerian description of stellar debris dynamics, have proven remarkably successful in describing the observed…
Interacting systems with zero thermodynamic curvature
Juan Rodrigo, Ian Vega
We review a conjecture by Ruppeiner that relates the nature of interparticle interactions to the sign of the thermodynamic curvature scalar , paying special attention to the cas…
