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…

Galactic Halos and rotating bosonic dark matter

Jorge Castelo Mourelle, Christoph Adam

Rotating bosonic dark matter halos are considered as potential candidates for modeling dark matter in galactic halos. These bosonic dark matter halos can be viewed as a dilute and…
