Quasinormal-mode redshifts of black holes in galactic halos with radial pressures
Che-Yu Chen, Hassan Hassanabadi, Soroush Zare
We investigate the black-hole quasinormal mode redshifts induced by a galactic dark-matter halo with nonvanishing radial pressure. The halo is described by an anisotropic fluid wit…
Black holes in depleted Dehnen dark matter halos with physical inner edges and strong-field observables
Hassan Hassanabadi, Soroush Zare
We construct a static and spherically symmetric black hole (BH) spacetime surrounded by a depleted Dehnen dark matter (DM) halo. The model describes a final equilibrium configurati…
Imprints of core/cusp dark matter distributions on black hole signatures in galaxies
Hassan Hassanabadi, Che-Yu Chen, Soroush Zare +1
In galactic environments, a host dark matter (DM) halo can imprint weak but coherent corrections on black hole (BH) strong-field observables. We construct an exact family of static…
Constrained thermodynamics and geodesic observables of an effective non-commutative Kerr-like black hole
H. Hassanabadi, L. A. López, N. Bretón +2
We investigate the horizon structure, constrained thermodynamics, and geodesic properties of an effective Kerr-like black hole in a non-commutative background. Deformation modifies…
Schwarzschild-like Black Holes Submerged in an Exponential Density Dark Matter Profile
Kuantay Boshkayev, Yassine Sekhmani, Soroush Zare +3
We study a class of Schwarzschild black holes embedded in an exponential-spheroidal dark matter halo, modelled by a phenomenological density profile . By solvi…
Optical and thermodynamic properties of Kerr-Bertotti-Robinson black holes
Hassan Hassanabadi, Michael R. R. Good, Soroush Zare +2
We investigate the thermodynamic and optical properties of Kerr--Bertotti--Robinson black holes, namely rotating black holes immersed in an external Bertotti--Robinson electromagne…
