Two shadows of a single black hole: Vacuum birefringence phenomena within Einstein-nonlinear-electrodynamics
Marco A. A. de Paula, Haroldo C. D. Lima, Pedro V. P. Cunha +2
The paper investigates photon propagation in black holes sourced by a nonlinear electrodynamics model, showing that vacuum birefringence leads to two distinct photon trajectories a…
Inspirals into bosonic dark matter stars and chirp mimickers
Caio F. B. Macedo, Haroldo C. D. Lima, Raissa F. P. Mendes +2
We investigate extreme-mass-ratio inspirals in which a stellar-mass compact object orbits a supermassive bosonic dark matter star, modeled as a boson star, using fully relativistic…
Spherical Einstein-Friedberg-Lee-Sirlin boson stars: Self-interacting solutions and their astrophysical appearance
Pedro L. Brito de Sá, Haroldo C. D. Lima, Carlos A. R. Herdeiro +1
We investigate boson stars within the framework of the self-interacting Einstein-Friedberg-Lee-Sirlin (E-FLS) model, constituted by a complex scalar field with a quartic self-inter…
