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…

Multi-photon ring structure of reflection-asymmetric traversable thin-shell wormholes
Caio F. B. Macedo, João LuÃs Rosa, Diego Rubiera-Garcia +1
We consider the observational signatures of thin accretion disks around a reflection-asymmetric traversable thin-shell wormhole. This wormhole, built in the framework of Palatini $…

Twinkle twinkle dark star: Oscillating profiles from dark matter scalar solitons
Nicolas Aimar, Caio F. B. Macedo, João LuÃs Rosa +1
Real scalar fields, e.g. the axion, cannot condensate into stationary solitonic configurations to form starlike structures, eventually either dispersing or collapsing. However, by…
