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…
Probing regular black holes with sub-Planckian curvature through periodic orbits and their gravitational wave radiation
Soroush Zare, Tao Zhu, Luis M. Nieto +2
Extreme mass-ratio inspirals (EMRIs) are among the key targets for future space-based gravitational wave detectors. The gravitational waveforms emitted by EMRIs are highly sensitiv…
Charged particle dynamics in singular spacetimes: hydrogenic mapping and curvature-corrected thermodynamics
Abdullah Guvendi, Semra Gurtas Dogan, Omar Mustafa +1
We analyze the dynamics of charged test particles in a singular, horizonless spacetime arising as the massless limit of a charged wormhole in the Einstein--Maxwell--Scalar (EMS) fr…
An algebraic approach to gravitational quantum mechanics
Won Sang Chung, Georg Junker, Hassan Hassanabadi
Most approaches towards a quantum theory of gravitation indicate the existence of a minimal length scale of the order of the Planck length. Quantum mechanical models incorporating…
Modified Kerr black holes surrounded by dark matter spike
Salvatore Capozziello, Soroush Zare, Luis M. Nieto +1
We study supermassive black holes (SMBH), surrounded by a dark matter (DM) spike, that can be found at the centers of Milky Way and galaxies and are accompanied by a s…
Hawking temperature of black holes using the EUP and EGUP formalisms based on the Einstein-Bohr's photon box
N. Farahani, H. Hassanabadi, W. S. Chung +2
In this paper, by studying the Einstein-Bohr's photon box for weighting a photon, we find that the effective Newton constant can be proposed by the extended uncertainty principle a…
Investigation of Unruh temperature of Black holes by using of EGUP formalism
Hassan Hassanabadi, Nasrin Farahani, Won Sang Chung +1
In this paper, we have used the extended generalized uncertainty principle to investigate the Unruh temperature and thermodynamic properties of a black hole. We started with a brie…
Spin-zero system of DKP equation in the background of a flat class of Gödel-type space-time
Faizuddin Ahmed, Hassan Hassanabadi
In this paper, we investigate the Duffin-Kemmer-Petiau (DKP) equation for spin-zero system of charge-free particles in the background of a flat class of Gödel-type space-times, and…
New generalized uncertainty principle from the doubly special relativity
Won Sang Chung, Hassan Hassanabadi
Based on the doubly special relativity we find a new type of generalized uncertainty principle (GUP) where the coordinate remain unaltered at the high energy while the momentum is…
Reply to "Comment on "Effects of cosmic-string framework on the thermodynamical properties of anharmonic oscillator using the ordinary statistics and the q-deformed superstatistics approaches""
Hadi Sobhani, Hassan Hassanabadi, Won Sang Chung
In this paper, we show the detail of our recent paper Effects of cosmic-string framework on the thermodynamical properties of an anharmonic oscillator using the ordinary statistics…
