Relativistic tidal divergences in circular orbits and the dynamics of light rings
Victor F. C. Vieira, Rafael P. Bernar, Caio F. B. Macedo
Tidal forces acting on orbiting bodies arise from inhomogeneities in the gravitational field, generating stresses that can deform or even disrupt these objects. In this work, we an…
Axial perturbations of hairy black holes in generalised scalar-tensor theories
Georgios Antoniou, Caio F. B. Macedo, Andrea Maselli +1
Gravitational wave observations can test the validity of General Relativity (GR) in the strong field regime. Certain classes of scalar-tensor theories indeed predict that compact o…
Extreme mass-ratio inspirals in ultra-light dark matter
Francisco Duque, Caio F. B. Macedo, Rodrigo Vicente +1
Previous works have argued that future gravitational-wave detectors will be able to probe the properties of astrophysical environments where binary coalesce, including accretion di…
Eternal binaries
Jaime Redondo-Yuste, Vitor Cardoso, Caio F. B. Macedo +1
The two-body problem is extensively studied in open systems and asymptotically flat spacetimes. However, there are many systems where radiation is trapped: they range from radiatin…
Imaging compact boson stars with hot-spots and thin accretion disks
João Luís Rosa, Caio F. B. Macedo, Diego Rubiera-Garcia
In this work we consider the observational properties of compact boson stars with self-interactions orbited by isotropically emitting (hot-spot) sources and optically thin accretio…
Tidal forces in dirty black hole spacetimes
Haroldo C. D. Lima Junior, Mateus M. Corrêa, Caio F. B. Macedo +1
Black holes can be inserted in very rich astrophysical environments, such as accretion disks. Although isolated black holes are simple objects in general relativity, their accretio…
