Dark-to-black super-accretion as a spin-imprinting mechanism for supermassive Kerr black holes
Saeed Fakhry, Nicolas Sanchis-Gual, Jorge Castelo Mourelle +2
The existence of supermassive black holes with masses and large dimensionless spins at high redshift remains a challenge to our understand…
Rotating Fermion-Boson Stars in -squared Gravity
Saeed Fakhry, Jorge Castelo Mourelle, Nicolas Sanchis-Gual +3
Fermion-boson stars are compact equilibrium configurations composed of ordinary fermionic matter and a bosonic dark component interacting only through gravity. Such systems provide…
Testing bosonic dark matter through white dwarf mass measurements
Jorge Castelo Mourelle, Nicolas Sanchis-Gual, José A. Font +1
Mass estimates of white dwarfs via electromagnetic methods, often differ from those obtained through gravitational redshift measurements, in some cases with discrepancies ranging i…
Reproducing galactic rotation curves with a two-component bosonic dark matter model
Jorge Castelo Mourelle, Nicolas Sanchis-Gual, José A. Font
Bosonic stars,hypothetical astrophysical entities, are generally categorized into two primary classes based on the nature of their constituent particles: Einstein Klein Gordon star…
Spinning boson stars in nonlinear sigma models and Universal Relations
Christoph Adam, Jorge Castelo Mourelle, Alberto García Martín-Caro +1
Boson stars are hypothetical compact objects derived from solutions of a self-gravitating complex scalar field. In this study, we extend the traditional models by generalizing the…
Universal Relations for Rotating Scalar and Vector Boson Stars
Christoph Adam, Jorge Castelo Mourelle, Etevaldo dos Santos Costa Filho +2
Bosonic stars represent a hypothetical exotic type of compact stellar objects that could be observed from the gravitational signal of coalescing binaries in current and future grav…
