Higher derivative Hořava-Lifshitz fermions: from superconductivity to atomic spectroscopy
A. A. Araújo Filho, K. E. L. de Farias, N. Heidari +2
We investigate an isotropic Hořava-Lifshitz fermion theory supplemented by a dimension-six spatial derivative operator, preserving first order time evolution while modifying the ul…
A general static and spherically symmetric black hole in traceless metric-affine bumblebee gravity
A. A. Araújo Filho, N. Heidari, V. B. Bezerra +1
We construct and analyze a general exact static and spherically symmetric black hole solution in traceless metric-affine bumblebee gravity by considering a vacuum expectation value…
Exploring a phantom Dirac-Born-Infeld regular black hole via particle emission, wave scattering and geodesics
N. Heidari, A. A. Araújo Filho, Iarley P. Lobo +1
We examine particle creation, evaporation, scalar wave absorption and scattering, and geodesic motion in the asymptotically flat regular black hole supported by a phantom Dirac-Bor…
A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission
A. A. Araújo Filho, Arun Kumar, N. Heidari +3
We investigate the geometrical, thermodynamic, and quantum emission properties of a rotating black hole immersed in a Hernquist dark matter halo. Starting from a static black hole…
Gravitational wave propagation in Hořava-Lifshitz gravity
A. A. Araújo Filho, J. L. A. Silva, N. Heidari +3
We investigate the generation and propagation of gravitational waves in the leading parity-even infrared truncation of Hořava-Lifshitz gravity, characterized by the modified tensor…
Accelerating electrically charged ModMax black hole solutions in gravity
B. Eslam Panah, N. Heidari, A. Rincón
Using the metric in the context of gravity coupled with the ModMax nonlinear electromagnetic field (the ModMax theory), we derive an exact black hole solution in…
Shadows and lensing signatures of a rotating black hole in a Hernquist dark matter halo
A. A. Araújo Filho, Arun Kumar, N. Heidari +3
We investigate the optical properties of a rotating black hole immersed in a Hernquist dark matter halo. The spacetime is generated from a static Hernquist black hole through the n…
Gravitational wave signatures and periodic orbits of a charged black hole in a Hernquist dark matter halo
N. Heidari, A. A. Araujo Filho, Iarley P. Lobo
In this work, we study the motion of massive test particles and the gravitational--wave emission associated with periodic trajectories around a magnetically charged black hole imme…
Gravitational waves in a minimal gravitational SME
A. A. Araújo Filho, N. Heidari, Iarley P. Lobo
In this work, we investigate the generation and propagation of gravitational waves within a minimal gravitational SME (Standard Model Extension). Starting from the modified gravito…
Imprints of non-commutativity on charged black holes
N. Heidari
This work presents a comprehensive investigation of the gravitational phenomena that correspond to a non-commutative (NC) charged black hole, by incorporating NC geometry through a…
Propagation effects of Lorentz violation in gravitational waves
A. A. Araújo Filho, N. Heidari, Iarley P. Lobo
We investigate the propagation of gravitational waves in the presence of Lorentz- and diffeomorphism-violating operators within the linearized gravitational sector of the Standard…
Particle production, absorption, scattering, and geodesics in a Schwarzschild-Hernquist black hole
N. Heidari, A. A. Araújo Filho, P. H. M. Barros
We investigate quantum and classical signatures of a Schwarzschild black hole embedded in a Hernquist dark matter halo. Starting from the exact spherically symmetric solution descr…
