Gravitational wave propagation in HoÅava-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 HoÅava-Lifshitz gravity, characterized by the modified tenso…
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…
Neutrino dynamics in a non-commutative spacetime
A. A. Araújo Filho, N. Heidari, Yuxuan Shi
We investigate neutrino dynamics in a spherically symmetric non-commutative black hole spacetime generated by a Lorentzian smeared matter distribution. We work with the leading-ord…
A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission
A. A. Araújo Filho, A. A. Araújo Filho, Arun Kumar +4
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…
Signatures of a de Sitter-core black hole in ringing, transmission and optical appearance
N. Heidari, A. A. Araújo Filho, V. Vertogradov and +1
We investigate a static, asymptotically flat black hole whose central region approaches a de Sitter vacuum. The geometry is controlled by the ADM mass and a core scale , a…
