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…
Phase-space structure and nonlinear dynamics of a charged particle on a helicoidal manifold under a magnetic field
Abdullah Guvendi, Hassan Hassanabadi, Semra Gurtas Dogan +1
We analyze the classical dynamics of a charged particle constrained to a helicoidally embedded Riemannian manifold in under a uniform magnetic field in the ambient s…
